Epstein-Barr virus (EBV) is one of the most common viruses in the world. EBV is easily transmitted through body fluids (mainly saliva), such as kissing and sharing drinks or tableware. According to statistics, 90%-95% people around the world have been infected, usually in childhood.

EBV infection can cause infectious mononucleosis or similar diseases, but it usually has no symptoms. Most EBV infection symptoms are mild and will disappear, but these viruses will persist and lurk in the body, and will be reactivated. In recent years, some studies have shown that long-term latent EBV virus is related to some chronic inflammation and various cancers, and some studies have found that EBV may be the pathogenic factor of multiple sclerosis (MS).

On April 12th, 2023, the team of Professor Don Cleveland from the University of California, San Diego published a research paper entitled Chromosomal Fragile Site Breakage by EBV-Encoded EBNA 1 at clustered repeats in Nature.

This study describes for the first time how Epstein-Barr virus (EBV) uses the fragile sites in the human genome to cause chromosome breakage, cause cancer, and reduce the human body’s ability to suppress cancer.

There are fragile sites in everyone’s genome, and these specific chromosome regions are more prone to mutation, breakage or deletion during DNA replication. These changes may be related to disorders and diseases, which may lead to genetic diseases and cancer.

Professor Don Cleveland

Professor Don Cleveland, the correspondent of the paper, said that this study revealed how EBV induced the breakage of human chromosome 11 and caused a series of genomic instability, which may activate the oncogene that causes leukemia and inactivate the main tumor suppressor gene. This also proves for the first time how to selectively induce the breakage of fragile DNA sites.

In this latest study, the research team focused on EBNA1 protein, a viral protein that persists in human cells infected with EBV. Previous studies have shown that EBNA1 will bind to a specific genome sequence at the beginning of EBV genome replication. This study found that EBNA1 also combined with a cluster of EBV-like sequences at a fragile site of human chromosome 11, where the increase of protein abundance would lead to chromosome breakage.

Previous studies have shown that EBNA1 can inhibit p53 gene, and p53, known as the "genome guardian", plays a key role in controlling cell division and cell death. Under normal circumstances, p53 can inhibit the occurrence and development of tumors, while mutant p53 is related to the growth of cancer cells.

The research team also examined the genome-wide sequencing data of 2,439 cancers of 38 cancer types from the genome-wide pan-cancer analysis project. They found that tumors with EBV infection showed higher levels of chromosome 11 abnormalities, especially head and neck cancer cases.

Julia Su Zhou Li

Julia Su Zhou Li, the first author of the paper and a postdoctoral fellow, said that for a virus that is ubiquitous and harmless to most people, it is still an ongoing effort to identify high-risk groups susceptible to latent infection-related diseases. This study shows that the susceptibility to EBNA1-induced chromosome 11 breakage depends on the control of the level of EBNA1 protein produced in latent infection and the genetic variation of the number of EBV-like sequences on chromosome 11 in each individual. Looking ahead, this discovery paves the way for screening the risk factors for the development of diseases related to EBV infection. In addition, blocking the combination of EBNA1 and EBV-like sequence on chromosome 11 can be used to prevent the development of EBV-related diseases.

The modern idol drama "Love in Spring", co-starred by Li Xian and Zhou Yutong, has officially ended. This drama was broadcast during the prime time of CCTV 8, and the ratings have been poor. Whenever there is no high-rated drama milk in front, it drops to 0.9 on average, and the lowest peak is about 0.7. Under the chassis of CCTV eight sets, it is a very low achievement to start with 1 casually and break 2 easily.

However, after it opened in Douban, everyone found that its score was not low, and 7.7 was a qualified modern idol drama. Therefore, Zhou Yutong, the heroine, is also said by everyone that no matter how popular she is, even after a circle of hot male artists cooperate, she is still cold.

The continuous ratings of Shangxing are all countdown.

If anyone’s brother and sister can have works to meet with you on CCTV, fans will inevitably take them out and brag about them. Especially under the background of the times when everyone shouts that broadcasting is victory, it is not easy to go to the stars, let alone be able to go to CCTV.

For example, even for top-class users like Andy and Dilraba, their TV series can be broadcast on Shangxing Channel, and it will take a long time for fans to set off firecrackers. Not to mention that if other idol artists can participate in the drama released by CCTV, they can’t walk sideways, because it shows that the drama is recognized from the production company to the content.

From last year to now, Zhou Yutong is an artist who has exported a lot. A modern idol drama "It’s just love", a costume drama "Young Tales of the Great Song Dynasty II", and then the just-concluded "Lover in Spring". Without kicking, there are new dramas, and all three of them met with you in front of the TV. However, the result of meeting is not so happy.

She and Leo starred in "Just Love", the hit period was Yunhe in 1875, and CVB was released in the eighth year. Well, let’s just say that the drama of falling in love is not in line with the audience of CCTV 8, and it is not to their appetite.

Then, a minority drama with a very good reputation, called the original team, was the same screenwriter as Joy of Life, and met with you at Hunan Satellite TV, the place with the largest young audience. In the end, CVB ratings are in the top five in the history of Hunan Satellite TV.

The just-concluded "Spring Lovers", eight sets of CVB of CCTV fell below 0.8, and the webcasting was not too bad, and it should be able to break 20 million. Although less than half a year has passed in 2024, it is obviously a countdown of CCTV eight sets. For two years, it’s the countdown of CCTV’s eight sets. I don’t know what Zhou Yutong thinks in his heart. Satellite TV itself is probably a sweat.

Acting skills pass CP is not enough.

Practically speaking, Zhou Yutong’s acting skills are not too bad. She even has the title of "chosen migrant worker" on a small book platform. Because most of the performances are modern dramas, the smell of social animals on my face makes everyone feel very real. She doesn’t have the grounding gas of a female star, and she has a badge around her neck, as if she really is an urban white-collar worker in the cubicle of an office building. In other words, people think that Zhou Yutong’s acting skills are up to standard, and people don’t play in the process of chasing plays. Zhou Yutong’s mouth spit out opinions and experiences about the workplace, which is not very contrary. However, we don’t think that the CP between Zhou Yutong and others is very impressive.

Far away, let’s take a recent play with Li Xian. There are a lot of kissing scenes between them, which is definitely a mutual pull between adults. Do what you have to do, it’s unambiguous. When the two actors went to sweep the building together during the TV series, Zhou Yutong and innocent girl, who had slightly curly hair and slim and beautiful figure, stood beside Li Xian, and the two men were beautiful. Do you feel CP? Absolutely, but it is far from the level of letting everyone go to the top, and it lacks the feeling of indescribable chemistry.

It is no wonder that people often say that CP sense is a kind of metaphysics, which is mysterious and wonderful. No matter what the audience does between two actors, a little subtle spark can make everyone intoxicated. Zhou Yutong, there is no such feeling, she is beautiful, she looks very tasty, and she stands with Li Xian very tasteful. However, this smell is not enough to make everyone feel infatuated and unable to stop.

The resources are ok, and sooner or later, the fire will come out.

Fortunately, Zhou Yutong’s resources are quite good. The reason for such a dense broadcast is that there has always been a drama at hand, and the cooperation is all popular actors, and the popular traffic of Leo, Li Xian and Song Weilong has swept past one by one.

The problem is that at this stage, everyone may be persistent actors, and they have to rely on CP to get angry. In fact, slowly, everyone will find that some people are not angry, which is also a way of fire. Everyone insists that they can’t spit out the fire, which is another kind of fire.

　　Xinhua News Agency, Beijing, August 28th (Reporter Leon, Zhang Manzi) As of 22: 00 on August 26th, the summer box office of China film market in 2023 exceeded 20 billion yuan, setting a new record for the summer box office. China’s summer box office jumped from nearly 17.8 billion yuan in 2019 to a new height of 20 billion yuan, injecting more confidence into the recovery of China and the global film industry.

　　China film industry is used to calling the three natural months from June to August every year as summer files. As the first summer file after China adjusted and optimized epidemic prevention and control measures, why did this summer file break the record? Analysts pointed out that cultural consumption, including movies, has gradually recovered. The types and themes of summer movies this year are diverse and rich, and popular works frequently appear, meeting the diverse needs of watching movies.

　　Yu Chao, deputy general manager of Capital Cinema, has the most outstanding feeling that "there are more outstanding films".

　　According to the data of the Lighthouse Professional Edition of the film data platform as of the morning of August 27th, the suspense film "She Disappeared" and the crime film "Put All Your Eggs on One Egg" ranked first and second in the summer box office list with 3.5 billion yuan and 3.3 billion yuan, followed by the mythical epic film "Goddess Part I" and the realistic film "The Octagon Cage", with box office of 2.4 billion yuan and 2.2 billion yuan respectively.

　　On April 21st, the cast members of "She Disappeared" were at the red carpet ceremony for the opening of the 13th Beijing International Film Festival. Xinhua News Agency reporter Chen Zhongyu photo

　　In the eyes of the industry, such a box office array is more healthy and stable than the box office champion of previous years, and the box office of the second or third place on the list has dropped to more than 1 billion yuan, showing that the overall quality of this summer’s movies is higher.

　　Chen Xuguang, director of Peking University Film and Television Drama Research Center, believes that the biggest feature of this year’s summer file is that the types and themes of films are more diverse, meeting the needs of audiences of different ages, "instead of simply focusing on student groups as before".

　　There are movies based on myths, legends and history, such as "The First Goddess" and "Three Wan Li in Chang ‘an", and there are movies with realistic themes, such as "Put all your eggs in one basket" and "In an octagonal cage", which play the role of "window" and let the audience better understand the society and protect themselves.

　　A good box office first stems from the excellent quality of the film. "China filmmakers pay more attention to ‘ Use money on the cutting edge ’ It also pays more attention to the quality of movies, and a number of domestic masterpieces have emerged. " Chen Xuguang said that there are a large number of movie audiences in China, and the types of movies should be as diverse as possible. "We are not afraid of no audience, but we are afraid that there are not enough good works.".

　　From June 21st to August 27th, the single-day box office of China film market broke through 100 million for 68 consecutive days, reaching a new high. Chen Jin, a data analyst of Lighthouse Professional Edition, pointed out that this sustained and stable box office performance has laid a sufficient foundation for the market to restore confidence, and the film industry has obvious signs of accelerating recovery. As of the afternoon of August 27th, the total number of screenings of this year’s summer file reached 33.7 million, setting a new record for the summer file.

　　The top six films in China’s summer box office this year are all domestic films, accounting for about 70% of the total box office. "Both the audience and the upstream and downstream of the industry have more confidence in the China film market after this summer file." Chen Jin said.

　　The Fifth Plenary Session of the 18th Central Committee of the Communist Party of China (CPC) was held in Beijing from October 26th to 29th, 2015, and General Secretary of the Supreme Leader made an important speech. The plenary session stressed that to achieve the development goals during the Thirteenth Five-Year Plan period, we must firmly establish and earnestly implement the development concept of innovation, coordination, green, openness and sharing.

　　This year is an important year for the implementation of the 13 th Five-Year Plan and the deepening of supply-side structural reform.

　　Whether the development goals of the "Thirteenth Five-Year Plan" can be achieved, there are 10 words that are crucial — — Five development concepts of "innovation, coordination, green, openness and sharing".

　　How important are the five development concepts for the current and future development of China? According to the Supreme Leader, the new development concept is baton and traffic light, which embodies the development ideas, development direction and development focus of China in the "Thirteenth Five-Year Plan" and even in a longer period.

　　Since the 18th National Congress of the Communist Party of China, the five development concepts have run through the economic and social development of China, and have really influenced our lives.

　　Advocating innovation: "China artifact" swipes the screen network, which has greatly improved my country.

　　In recent years, China’s economic growth has slowed down and its development has entered a "new normal", but some people think that China’s economy is dying! In response to this question, the attitude of the supreme leader is very clear. "I have firm confidence in the sustained and healthy development of China’s economy." At the same time, he also gave a "prescription" for the problems in development: the fundamental way out for China’s economic development to break through the bottleneck and solve deep-seated contradictions and problems lies in innovation.

　　How effective has this medicine been in the past five years? For ordinary people, the China artifacts that have been swiped on the Internet may have the deepest feelings: Beidou, the world’s most accurate navigation satellite system; Tiangong-2, the first real space laboratory; the world’s fastest supercomputer, Shenwei Light of Taihu Lake; Mozi, the world’s first quantum science experimental satellite; C919, a large domestic aircraft with international mainstream standards; and advanced world level. …

　　When we sigh "awesome, my country" again and again, we really feel the "welfare" brought by innovation and development. People in China who have these "artifacts" have a more convenient life, a more secure life and a harder waist abroad!

　　In the ranking of global innovation index published by the World Intellectual Property Organization in 2017, China rose from 35th in 2013 to 22nd, ranking first among middle-income economies.

　　Whether China’s economy will work or not, don’t fight a war of words, just prove it to you with tangible innovation achievements!

　　Pay attention to coordination: a well-off society in an all-round way is indispensable, and the promise to the people must be fulfilled.

　　In history, there are many examples of countries falling into a "trap" and stagnating because of unbalanced development. After China’s economic development has entered the "new normal", all kinds of speculations and worries about the "middle income trap" are rampant!

　　Undeniably, there are some unbalanced problems in the development of China, for example, in some places, "cities are like Europe, and rural areas are like Africa", and in some places, people are "pocketed and empty-headed" and so on. The proposal of coordinated development is an effective way to face up to and solve problems.

　　In the past five years, many achievements in the coordinated development of regions, urban and rural areas, economy and society can be personally experienced by ordinary people: the construction of rural teachers has been placed in a strategic position of giving priority to development, benefiting more than 3.3 million rural teachers and more than 40 million rural students; More than 31 provinces have introduced implementation plans for household registration system reform, and generally proposed to cancel the distinction between agricultural registered permanent residence and non-agricultural registered permanent residence and relax restrictions on settlement; The reimbursement rate of medical insurance for employees and residents is above 80% and 50% respectively … …

　　Coordinated development is not only to avoid falling into the trap, but also a solemn commitment made by the party to the people — — Build a well-off society in an all-round way by 2020. I believe that as long as we implement the concept of coordinated development and make up the weak areas, weak areas and weak links, an all-round well-off society will be realized as scheduled.

　　Advocating Green: "Lucid waters and lush mountains are invaluable assets" has become the consensus of the whole people.

　　While China has become the second largest economy in the world, the deteriorating ecological environment has also become the biggest "worry" for the people.

　　For economic growth, sacrifice the environment and ecology! For Jinshan Yinshan, I lost green mountains and green hills! This "GDP-only" development concept will never be agreed by ordinary people.

　　The supreme leader saw the crux of the problem and decisively put forward that "it is better to have green mountains and green hills than Jinshan Yinshan".

　　On the one hand, we will remove the curse from leading cadres at all levels. "Even if the GDP slips to the seventh and eighth places, it has made progress in green development and contributed to controlling air pollution and solving smog, then you can hang red flowers and be a hero."

　　On the other hand, the central environmental protection inspector has covered 23 provinces, put 1,183 cases on file for investigation, detained 1,103 people and held 11,390 people accountable.

　　Although, there is still a long way to go to solve environmental problems. But fortunately, after five years of hard work, the concept of "Lucid waters and lush mountains are invaluable assets" has become the consensus of the whole people. As long as China society continues to exert its strength from top to bottom, the "beautiful China" with clear sky and clear water will not be far away.

　　Thick planting and opening up: China has gained consensus and won respect in the international community

　　Nearly 40 years of reform and opening up, China’s social outlook, people’s living standards and international status … … Have undergone earth-shaking changes. And the occurrence of this series of changes, as the supreme leader said, "depends on unremitting efforts to promote reform and opening up."

　　How much does reform and opening up weigh in the hearts of the supreme leader? After taking office as general secretary, he left Beijing for his first inspection tour and came to Guangdong. At that time, he clearly pointed out that "reform will not stop and opening up will not stop". In the past five years, from the implementation of the FTZ strategy to the construction of the Belt and Road Initiative, from the G20 Hangzhou Summit to the upcoming meeting of BRICS leaders in Xiamen, from becoming one of the largest foreign investors in the world to China, which has contributed over 30% to the world economic growth annually and is already the "first engine of world economic growth", the pace of opening up has never stopped.

　　Adhering to the concept of open development has also enabled China to gain consensus and win respect in the international community. After the Belt and Road Initiative was launched, more than 100 countries (regions) and international organizations expressed their active support and participation, and 40 countries and international organizations signed cooperation agreements with China.

　　China’s opening to the outside world does not seek hegemony or expansion, but seeks win-win cooperation. At the same time of its rapid development, it has also provided development opportunities for all countries in the world and promoted world economic growth.

　　Promote sharing: strive to turn the "concern" of ordinary people into reality.

　　"Sense of gain" is a word that people are very concerned about now. The working class is concerned about whether the salary can be higher, the retirees are concerned about whether the pension can be higher, and the rural people are concerned about whether the income gap with the city people can be smaller … …

　　In fact, these are not only the concerns of ordinary people, but also the concerns of the CPC Central Committee.

　　In the past five years, the CPC Central Committee with the Supreme Leader as the core has never forgotten the solemn commitment of "making people have more sense of reform" and strived to turn the "care" of the people into reality: in 2016, the per capita disposable income of the national residents increased by 44.3% compared with 2012; Pensions have achieved "twelve consecutive rises"; The income gap between urban and rural residents has dropped to about 2.8 times; The rural poor population is decreasing by more than 10 million people every year … …

　　China’s economic development has achieved today’s achievements thanks to more than 1.3 billion people, and the fruits of development should be shared by more than 1.3 billion people. In the future, whether it is to build a well-off society in an all-round way or to realize the great rejuvenation of the nation, it is inseparable from the support of the concept of shared development.

　　In the past five years, China has solved many problems through development, but it still faces some problems. The five development concepts are put forward in view of the outstanding contradictions and problems in China’s development. Unswervingly implementing the five development concepts will surely lead China to approach the goal of national rejuvenation step by step and step by step to the center of the world stage.

Native tree species refers to the natural distribution of trees in this area or the long-term growth of local trees. National Forestry and Grassland Administration recently released that China actively adopts native tree species and grass species to carry out afforestation and greening. At present, all the artificial afforestation in China basically uses native tree species.

National artificial afforestation basically uses native tree species.

Since 2021, National Forestry and Grassland Administration has approved 47 improved varieties of forest trees, all of which are native species. At present, 670 indemnificatory nurseries have been built in China, focusing on cultivating fine varieties and strong seedlings of native broad-leaved tree species, shrub species and high-quality economic forest species, with an additional seedling production capacity of nearly 100 million plants, thus ensuring the demand for native tree seedlings for national greening.

In promoting the construction of forest cities, National Forestry and Grassland Administration requires that native tree species should be the main species, and the utilization rate of urban native tree species should reach more than 80%, so as to increase the application of native tree species and grass seeds in urban greening.

National Forestry and Grassland Administration has instructed 29 provinces to issue a list of main native tree species, and made clear the suitable areas and suitable greening types of native tree species, which provided a basis for popularizing the use of native tree species. The "Reference List of Major Cultivated Precious Tree Species (2022)" was issued to guide all localities to actively cultivate local precious tree species.

Wangkui, Heilongjiang: Native Tree Species in Urban Greening and Forestry Engineering "Playing the Leading Role"

Wangkui County, Suihua, Heilongjiang Province, is an important commodity grain base in China and a key area for the construction of the "Three North" shelter forest system project. The local area combines urban greening with key forestry projects, afforesting according to local conditions, and building ecological barriers with native tree species.

CCTV reporter Shi Yuyu:The tree species used in the "Three North" shelter forest in Wangkui County, Suihua City, Heilongjiang Province is the native tree species Larix gmelinii, which has the characteristics of evergreen all the year round and tall trees, and can provide effective shelter for the farmland next to it.

Entering Wangkui County, a series of "landscape green corridors" came into view. Since it was incorporated into the "Three North" shelter forest construction project system, according to the long, cold and dry climate characteristics of northeast winter, the local area mainly planted native tree species with cold resistance, drought resistance and easy growth, and the utilization rate reached over 90%.

Zhang Jingbing, director of afforestation station of Forestry and Grass Bureau of Wangkui County, Suihua City, Heilongjiang Province:In the past, there was no such shelter forest. Because the wind blew our corn down, this phenomenon was called "wind scraping the ground". Now, with the shelter forest, this "wind scraping the ground" phenomenon has been greatly reduced.

After years of "Three North" shelterbelt construction, the farmland shelterbelt area in Wangkui County has reached 4,900 hectares, effectively sheltering 135,000 hectares of farmland, accounting for more than 95% of the county’s farmland area.

Not only did the "Three North" project choose native tree species, but also Wangkui basically used native tree species in urban greening. With the goal of "the city is in the forest, the road is in the green, the building is in the garden, and the people are in the landscape", the local green garden projects such as Wangkui Botanical Garden have been implemented.

Wang Shuqi, Deputy Director of Wangkui Garden Construction Service Center, Suihua City, Heilongjiang Province:The Botanical Garden covers an area of 450,000 square meters, all of which are local varieties, including spruce and Pinus sylvestris var. mongolica. It adapts to the local climate and grows vigorously.

At present, the urban greening coverage rate in Wangkui County is 40.38%, ranking first in Pingyuan County of Heilongjiang Province.

Sun Chenggang, Deputy Director of Wangkui Garden Construction Service Center, Suihua City, Heilongjiang Province:In combination with the construction of the "Three North" shelterbelt project, we adhere to the principle of respecting nature and adapting trees in suitable places, giving priority to the selection of excellent native tree species, so that urban residents can feel real benefits.

Shijiazhuang, Hebei province: strengthening scientific research and cultivation to improve the quality level of native tree species

In Shijiazhuang, Hebei Province, the research and application of local native tree species have been strengthened, new tree species and new strains have been cultivated, and the quality level of local tree species has been continuously improved.

The recent high temperature weather in North China has made the Woods in the park a good place for many citizens to enjoy the cool.

Shijiazhuang citizen Li Xupeng:The park is also tree-lined. Even in a high temperature day of more than 30 degrees Celsius, you won’t feel particularly hot and sunburned if you come here for a walk and enjoy the cool.

Shijiazhuang citizen Qiao Jing:Because its flowers in spring are very beautiful, I was attracted by this flower, and then I looked it up and found it was called a neem tree.

The neem tree mentioned by the citizens is an ancient native tree species, which was recorded in Qi Min Yao Shu in the 6th century A.D. and widely distributed in northern China.

However, in the long-term growth and development process, problems such as single variety and loose wood have also appeared in neem. In order to fully explore the excellent characteristics of this ancient native tree species, foster strengths and avoid weaknesses, a "research team for the development and application of neem germplasm resources" was established in the local area.

Tian Guoying, Dean of Shijiazhuang Agricultural and Forestry Research Institute, Hebei Province:Together with China Academy of Forestry, Hebei Normal University and other scientific research units and universities, we formed a research team to excavate and utilize the native tree species Melia azedarach, and cultivated 8 new varieties and strains successively.

Nowadays, in Shijiazhuang, there are more than 20 native tree species such as Melia azedarach, which are widely used. These native tree species have strong adaptability and resistance to the local growth environment, especially to extreme low temperature or high temperature. At the same time, it is easy to plant and has a high survival rate, which can maximize its own characteristics and meet the greening effect.

Fangchenggang, Guangxi: Casuarina equisetifolia, the "guardian of the sea", greening the city and coast.

Fangchenggang, Guangxi, located at the southernmost tip of Chinese mainland coastline, is a typical coastal city with Beibu Gulf in the south. Usually, the wind and sand in coastal cities are relatively heavy, so greening should not only pay attention to beauty, but also consider wind and sand fixation. Casuarina is an excellent tree species with three characteristics. Let’s get to know it together.

On the sea side of the West Bay in Fangchenggang City, Guangxi, rows of Casuarina trees grow along the coastline, forming a shelterbelt and a unique urban landscape. Casuarina equisetifolia is an evergreen tree of Casuarina, which is salt-tolerant and sand-resistant. It is a pioneer tree species in coastal shelterbelts and is known as a loyal "guardian of the sea".

Zhong Yu, Head of Garden Department of Fangchenggang City Management Supervision Bureau, Guangxi:Because its root system is very developed, it has a very good protective effect on wind, and its leaves are very thin, and it is a scale leaf, so its demand for water is much smaller than that of other broad-leaved trees, so its wind-proof and sand-fixing ability is very good.

Not only that, Casuarina grows rapidly, with a height of 30 meters. Coupled with its beautiful tree shape, Casuarina is also used as a street tree and has a good performance in urban greening.

Su Xuepeng, Director of Nursery of Forest Seed Breeding Center in Fangchenggang City, Guangxi: Especially in our coastal city, if it is a seawall or a beach, this kind of Casuarina tree is really beautiful.

According to the data provided by the garden department of Fangchenggang City, at present, more than 60% of the urban greening trees in Fangchenggang City are native trees like Casuarina. Because of their strong adaptability and strong resistance to natural disasters, native tree species are gradually showing their value with the increase of dosage.

Zhong Yu, Head of Garden Department of Fangchenggang City Management Supervision Bureau, Guangxi:The salinity and alkalinity in the urban mudflats are very high, and it is very difficult to survive by planting other trees. However, if Casuarina equisetifolia is planted, it can effectively form a certain green barrier, which can effectively increase the green quantity of our coastal cities.

　　Researchers at the University of Colorado recently published the latest research results in the journal Nature Earth Science, pointing out that global warming will have a far-reaching impact on the distribution of wind energy resources around the world. By the middle and late part of this century, the available wind energy resources in the northern hemisphere will be greatly reduced, while the wind energy resources in some areas in the southern hemisphere may increase sharply, and the overall wind power development potential will shift to the south.

　　1. Distribution or transfer of wind energy resources to the southern hemisphere

　　The polar regions are cold and the equator is warm, and the westerly winds prevail all the year round in the mid-latitudes of the northern and southern hemispheres, which is also called thermal wind. In this wind belt, the average wind speed is greater than other places, and a large number of wind energy resources are gathered, covering many countries in the northern hemisphere, including China. Under the background of climate change, the change of mid-latitude westerly belt will directly affect the utilization potential of wind energy resources.

　　The latest research results of the University of Colorado in the United States believe that global warming will have a far-reaching impact on the distribution of wind energy resources around the world. By the middle and late part of this century, the available wind energy resources in the northern hemisphere will be greatly reduced, while the wind energy resources in some areas in the southern hemisphere may increase sharply.

　　Using the simulation results of supercomputer, the researchers discussed the evolution of wind energy resources in two different scenarios of greenhouse gas emission in the future. The first is a medium emission scenario, assuming that carbon emissions reach the highest in the middle of this century and then remain stable; By the end of this century, the concentration of carbon dioxide in the atmosphere is about 1.5 times of the current concentration, and the global average temperature is warming by 1.1 to 2.6 degrees Celsius. The second scenario is a high emission scenario, corresponding to the development mode of slow improvement of energy structure and lack of climate response measures, carbon emissions will continue to increase, the concentration of carbon dioxide in the atmosphere will exceed the current three times by the end of this century, and the global temperature will rise by 2.6 to 4.8 degrees Celsius.

　　The results show that the wind energy resources in the northern hemisphere will be significantly reduced in both moderate and high emission scenarios, especially in the mid-latitude areas including northwest China, Siberia, Northeast Asia, the United States, Canada, Britain and the Mediterranean coast, that is, along the westerly belt of the northern hemisphere. Under the high emission situation, by the end of this century, the wind energy resources from Inner Mongolia to Northeast China will even be reduced by 10% to 20%.

　　The wind energy resources in the southern hemisphere will not change much under the medium emission scenario, but will increase greatly under the high emission scenario. Especially in the high emission scenario, by the end of this century, the wind energy resources in eastern Brazil and northeastern Australia will increase rapidly by more than 40%.

　　2. The reason is that the warming ranges of the North and South poles are different.

　　This difference may be attributed to the fact that global warming affects the evolution of wind belts in the northern and southern hemispheres in different ways. In the northern hemisphere, arctic warming and sea ice melting are a positive feedback process that promotes each other, so that under the background of global warming, polar warming is more obvious; As a result, the temperature gradient between the equator and the polar regions is weakened, and the wind speed in the mid-latitude westerly belt is reduced as a whole. Some simulation results also point out that due to the significant warming at high latitudes, the cold-warm confrontation between the north and south sides of the mid-latitude region is weakened, and the activity of the storm system is reduced as a whole, which is also a reason for the decrease of wind energy resources.

　　In the southern hemisphere, especially in high emission scenarios, Antarctic warming is not as obvious as land warming in central South America, southern Africa and Australia. The temperature gradient between this part of the continent and the ocean at the same latitude increases, which becomes the dominant factor in the change of wind belt intensity. Land warming is faster, land thermal depression is enhanced, land-sea pressure gradient is increased, wind speed is increased, and wind energy resources are increased. Except Antarctica, the southern hemisphere continent is mainly distributed in tropical and subtropical regions, so the overall increase of wind energy resources is also most obvious in tropical and subtropical regions. It is worth mentioning that in the middle and high latitudes of South America and Australia, wind energy resources still tend to decrease, similar to the northern hemisphere.

　　3. The probability of extreme gale in northern Europe has increased.

　　The confrontation between the cold and warm air masses in the north and south is common in the westerly belt, which is also called the front. If there is a small disturbance in the atmosphere, for example, one side of the air mass moves to the other side actively, and the trajectory of the air mass deflects under the action of geostrophic deviatoric force, it will induce a large-scale atmospheric vortex, which is also called frontal cyclone. From the climate point of view, the area where frontal cyclones frequently occur and pass through is the area "located on the storm track", and the average wind speed is usually larger than other areas.

　　But if you want to use wind energy, the bigger the wind, the better. Extremely violent gusts will actually cause damage to windmills. The design of windmills is generally based on the criteria such as the maximum wind that can cope with a few years (for example, 50 years), which is directly related to the statistical data of local climate background.

　　Scientists use supercomputers to simulate northern Europe. The results show that if the global climate warms, the mid-latitude "storm track" will move northward as a whole, and the number of frontal cyclones will decrease, but the intensity of a single storm will increase. As a result, the frequency and intensity of extreme winds in northern Europe will increase. This is not good news for windmills designed according to past climate data standards, and it also means that new wind farms must consider the possibility of withstanding stronger storms in the future.

　　Corresponding to the extreme wind that may increase, the extreme waves at sea will also increase. The research on the future evolution of wind and waves in the North Atlantic shows that the current "once in 20 years" big waves may appear every 4 to 12 years in 2080; The climate simulation of the North Sea in Europe shows that by the end of the 21st century, the average height of waves will rise by 5% to 8%. Because of the limited land space and greater friction resistance, offshore wind power generation is the hot direction of current development; The double test of wind and waves poses a new challenge to the construction of offshore wind farms in mid-latitude areas. However, in areas with lower latitudes, such as the Mediterranean coast, because the storm track moves northward, the wind and waves in the future climate outlook will be reduced.

　　4. Warming is a double-edged sword for high latitudes.

　　In high latitudes or arctic regions, cold weather is one of the reasons that hinder the popularization and application of wind power generation. Windmill blades are exposed to humid air with sub-zero temperature, and once they are frozen, the blades will lose their balance, the resistance will increase, the efficiency of wind power conversion will be reduced, and there are potential safety hazards. According to statistics, in Finland, 9%-45% of windmill stalling events are related to icing. Of course, the problem of icing can be overcome to some extent by designing blades that are not easy to gather ice and snow and using current heating, but it will also make the cost of operation and maintenance higher.

　　Climate warming may be good news for these areas. Supercomputer simulation results show that at the end of this century, the frost period in high latitudes will be obviously shortened and the frequency of icing will be greatly reduced, regardless of the assumed temperature rise. In some parts of Scandinavia, the icing frequency will even drop by 100%. At the same time, because the storm track moves northward, the high latitude zone will be more frequently affected by the frontal cyclone system, and the potential wind energy resources will become more abundant. As a result, some areas that are not suitable for the layout of wind farms may become new territories for opening up wind energy resources in the future.

　　Corresponding to the temperature rise, the permafrost zone in high latitudes will be reduced, which will bring both advantages and disadvantages. First, because the scope and depth of frozen soil layer are reduced, it will be more convenient to lay transmission lines and build wind farms. Secondly, if the frozen soil layer continues to melt, how to design the windmill base becomes a problem, because the stress and support relationship between the windmill and the soil will continue to change, and there will be the risk of lodging if it is slightly unbalanced. How to weigh the gains and losses, reduce risks and expand benefits depends on the wisdom of engineers.

　　Not only for onshore wind farms, but also for offshore wind farms in high latitudes, especially for the region with the fastest growing number of offshore wind farms — — For Europe. The study of future sea ice evolution shows that the number of days covered by sea ice in the North Baltic Sea and the Gulf of Bosnia will be reduced from the current 130-170 days to 0-90 days in the later part of this century, and many areas will not even be frozen all year round. However, the decrease of sea ice will make the foundation stability of offshore windmills worse, and it is more vulnerable to the damage of strong winds and waves. At the same time, rising sea level will also increase the risk that the windmill base will be flooded. However, the melting of glaciers will reduce the salinity of seawater, which will help to slow down the corrosion of seawater to the windmill base and transmission line materials.

　　Extended reading

　　The potential of wind farms such as Jiuquan may decline.

　　At present, the world’s largest wind power base is located in Jiuquan, Gansu, China. By 2012, the installed capacity of wind power has exceeded 6,000 megawatts, which is equivalent to supplying the electricity demand of the whole UK, and this figure is still rising. Gansu is located in the wind energy-rich zone in northwest China-Mongolia, with high wind speed all year round and wind energy density exceeding 150 watts per square meter. It is an ideal place for China to build wind power plants, and it has also played an important role in promoting local employment, taxation and economic development. If the climate warming continues, the potential of wind power in this region is likely to decline, and the potential of existing wind power equipment cannot be fully exerted. Many countries in the mid-latitude zone of the northern hemisphere, including China and the United States, will face the same problems, which will also add more pressure to the realization of human energy conservation and emission reduction goals.

　　The researchers pointed out that the current assessment and layout of wind power generation capacity are mostly based on past climate data statistics, but rarely consider the impact on the distribution of wind energy resources after the future atmospheric circulation changes due to human activities. The new research provides a new reference for the economy and sustainability of wind power plant layout in the future, and for decision makers to measure and plan alternative energy strategies.

　　In recent years, with the description of real life and the restoration of hot spots of the times, realistic works often detonate social topics and enjoy high ratings. Among them, the industry drama that reveals the inside story of the industry and tells the story of the workplace is a hot topic, covering many types of industries such as finance, lawyers, real estate, brokerage and public relations, but it is still a minority that can truly present the industry ecology and break through the expression boundary. Recently, the public relations industry drama "Emergency Public Relations", which was broadcasted on CCTV-8 and Youku platform, achieved a breakthrough.

　　As the saying goes, "amateurs watch the excitement and experts watch the doorway". From the perspective of watching the excitement, the work with gorgeous appearance and rich content is often the type targeted by industry drama creators, and public relations is one of them. Public relations, in the public’s cognition, is often well-dressed, complicated, powerful and mysterious. Public relations industry dramas seize the public’s curiosity, often start with hot events that focus on disputes and multi-party games, create story scenes with strong conflicts and strong dramatic reactions, and devote themselves to showing the decisive strength and resolute action of public relations people, thus mobilizing the audience’s enthusiasm for watching. For example, last year’s hit public relations industry drama "Perfect Relationship" started with the star derailment event that netizens are most keen on watching, showing how public relations people can help artists avoid being tracked by reporters in a short time, give the best plan, coordinate the relationship among the three, and finally calm down the whole process of public opinion crisis. The whole process is both exciting and realistic, and it is very enjoyable to watch. However, after watching it, how to dig deep into the industry and show the doorways of the workplace is often overlooked, which is why domestic industry dramas are often criticized for being vain and ungrounded.

　　Domestic public relations industry, as a new industry with the development of China’s modern economy, has gone through 40 years of initial and development before it came out of the misunderstanding of colored glasses. Behind it, countless public relations people fought day and night to vindicate it. The efforts and struggles behind them, their ordinary and greatness need to be presented more in public relations dramas, and there are more stories to be seen in this industry. Taking the story of crisis public relations expert Lin Zhongshuo as an incision, Emergency Public Relations tells the hardships behind his game with all parties and the resolution of the crisis, showing the ideal light of "Lin Zhongshuo" sticking to purity and justice and keeping the pulse at the bottom line, and opening up a new height of public relations type TV drama creation.

　　First, the integration of small details and big events makes the story more credible. Good details are the nectar of the story, which can expand the connotation of the story. Emergency Public Relations mostly involves big brands and big events, but in creation, it pays great attention to the control of details, thus reducing the sense of distance and strangeness between the public relations industry and the public and making it more sensible. For example, in the second case of the play, a middle-aged man who was under the pressure of supporting his family died of cancer, and the fact that he had been overworked under the wolf culture for a long time was also exposed, but he was dismissed because he could not meet the KPI requirements. Subsequently, an article by WeChat official account, Anxiety of the Quasi-Middle Class, triggered further fermentation of public opinion, and the content of this article, for example, caused a sensation in reality many times, which made the audience feel strongly substituted. Many netizens even discussed hot topics such as 996, 007 and middle-aged unemployment in the barrage area, just like the debate scene. There are many details like this. For example, every time a crisis occurs, netizens who seem to copy Weibo’s comments comment on the scene, such as various workplace concerns. Lin Zhongshuo joined the company as an airborne leader, and his colleagues who were forced to transfer to other departments were dissatisfied. Some colleagues clamored that they would rather leave their jobs than enter the new department, while savvy colleagues said: We are just surprised. Come and find out the situation. Others are making trouble, which has nothing to do with us. Netizens commented, "It’s too real. Who installed a camera in our company?" These vivid details pave the way for the conflict trend of every major event, which makes the play have a real sense of modern workplace.Characters are also more representative.

　　Second, individuals and groups reflect each other, showing the complex humanity behind multiple games. Public relations, also known as public relations, also means that it involves both individuals and the public as a whole, and is closely related to everyone in society. How to show the complexity of human nature behind it is the key to the deep development of the play. As a crisis public relations agent, Lin Zhongshuo should safeguard the interests of customers, but at the same time he also insists on justice in his heart. As a media person who upholds justice, Xu Wenwen also needs to consider that one of her articles may become a knife that hurts people. Lawyer Yuan Wei often has conflicts between truth and jurisprudence. The public, too, was able to avenge the victims in anger yesterday, but it may also change its direction in tomorrow’s changing information and become the perpetrators of cyber violence. "Emergency Public Relations" presents the struggles and thoughts of different individuals and groups in one case after another, and also makes the off-screen audience further reflect on themselves, how to make their own choices and whether their ideas are objective enough before complicated situations. For example, the third case of the play. The case revolves around the sexual assault of a guest in Diyun Hotel by a waiter. Through investigation, Lin Zhongshuo found that behind it was a "rape performance" made by his competitor Fang Li and Yizhuang Hotel. His assistant tracked down the actress in this incident. The actress was upset because of the public opinion of the incident and thought of her ideal decision to be an actor. However, the actor in this incident would rather admit sexual assault than confess because the other party paid off his gambling debts.Considering that the incident has no room for change, in order to calm the crisis as soon as possible, Lin Zhongshuo and Diyun Hotel can only choose to bear the consequences of the incident, and the relevant responsible persons voluntarily resign and strengthen further rectification. Among them, the incident is not without a chance to make a comeback. Xu Wenwen wanted to reverse public opinion through interviews with actresses, but she chose to give up considering that the fate of an actress was ruined. Lin Zhongshuo’s assistant found evidence that Fang Li and Yizhuang Hotel joined forces, but this incident would affect her good friend’s ability to stand in the industry from now on, and Lin Zhongshuo also gave up. In this incident, human nature is facing many tests, and finally it can only seek a compromise balance. The proposition left to the public is that if public opinion is more rational, there may be better choices. "This drama is a panoramic observation of social events from the perspective of crisis public relations industry, such as domestic violence, hotel safety accidents, lack of emotional education, cyber violence, etc., which is more or less connected with the social hotspots I usually pay attention to. We hope to guide the audience to look at and discuss these hot events rationally, get some insights, and make some changes in action. "As Huang Xiaoming said in an interview, changes in groups will give individuals more possibilities.

　　Third, the industry is related to industry values, and the ideals and beliefs of the workplace are tapped. The significance of the existence of industry drama is not limited to telling some dramatic stories, but should show the values and professional ideals that the industry should have and give everyone who works hard in ordinary posts a sense of identity. This is the energy that industry drama should have. This is also the reason why "Emergency Public Relations" is different from ordinary public relations dramas. The whole drama has always been committed to the transmission of industry values. At the beginning, the play put forward the meaning of public relations. "What’s the point of public relations if it only considers the interests of customers and doesn’t consider the public interests?" In the first incident, international airlines ignored the rights and interests of customers and blindly pursued interests. Facing this incident, reporter Xu Wenwen mentioned the issue of values in a conversation with Lin Zhongshuo. If everyone ignored the positive values for the benefit, what would the world be like? In the end, due to the high profile and interest-oriented values of international aviation, Lin Zhongshuo gave up this customer, and also guided Xu Wenwen to attack international aviation from the perspective of monopoly, and finally made it withdraw from the Asia-Pacific market. In the second case, the corporate wolf culture was criticized for overemploying people. General manager Hua made no apologies for the dismissal of middle-aged employees, and even accused the employees’ families of extortion after their death from cancer, which made public opinion stunned. Lin Zhongshuo tried his best after the notice of termination was issued by General Manager Hua, and finally persuaded him to withdraw the charges against his family members by showing General Manager Hua that it was not easy for middle-aged employees to take care of their relatives.All this has long gone beyond the scope of public relations, but this is the humanistic care that public relations people should have. As the opposite of the drama’s values, Fang Li has dealt a fatal blow to many enterprises through unfair competition by unscrupulous means for profit, but he has sold clients’ stocks through securities lending and illegally made profits. Therefore, both his father-in-law and his former boss look down on him. His existence highlights the value of people like Lin Zhongshuo, and further emphasizes the importance of a sense of justice and responsibility in the workplace. I believe that with the development of the plot, he will also be reviled.

　　360 lines, all lines are wonderful. I believe that with the breaking of high-quality industry dramas such as Emergency Public Relations, more creators will be awed by the creation of industry dramas, respect the ordinary persistence of everyone in the workplace, show every effort behind success, and light a beam of light for those who are struggling silently.

　　Cctv newsIn Tongzi County, Zunyi City, Guizhou Province, there is such a rural teacher. In the past thirty years, he has made unremitting efforts to raise money for poor local students. Thanks to his efforts, none of the local poor students dropped out of school because of family financial difficulties. Up to now, he has helped thousands of poor students.

　　This is Chloe Wang, a caring person in Zhejiang, and cost of living allowance, who gave this (child) subsidy. This is 400 yuan in May.

　　At present, the person who is handing over the donation from caring people to Zhou Xiaoqiang, a villager in Shuihe Village, Jiuba Town, Tongzi County, is called Huang Jinlong. Zhou Xiaoqiang is an accurate poverty alleviation household in the village. There are four people in the family. His eyes and face are sick, his wife is mentally handicapped, and his elderly mother fell to the cervical vertebra a few years ago. All three adults are on subsistence allowances, and the remaining one is a child who just attended kindergarten. Due to the difficulties of life, Huang Jinlong helped to contact a caring person in Zhejiang and began to support his family in December last year.

　　Villager Zhou Xiaoqiang:It’s difficult for little kids to go to school. We need this money every half semester. Teacher Huang needs caring people to help us, so it’s better. I really want to thank him and Mr. Huang for finding caring people to help us.

　　It is understood that this year is the 30th year for Huang Jinlong to raise money for poor local students.

　　In 1988, Mr Huang Jinlong began to help poor students for the first time. At that time, his monthly salary was two or three hundred yuan, and every year he had to pay several thousand yuan in tuition for poor students. Sometimes even his salary is not deductible. Although his family understood and supported him after his persuasion, after several years, Mr. Huang felt that this was not a long-term solution.

　　Jinlong HuangIn 1988, I did it alone. Later, there were too many poor students. I thought that one person’s strength was too thin, so I thought of foreign aid and let more caring people lend a helping hand.

　　Running around for half your life is only for one and you can’t be less.

　　Since 1991, while teaching, Huang Jinlong has officially started the road of asking for foreign aid. And there is only one belief in his heart: no less for one.

　　With the information of poor students from his own field survey, Huang Jinlong asked around where there were good people who were willing to help them go to school. After finding individuals, Huang Jinlong began to look for unit funding.

　　Jinlong HuangSometimes the door is closed, but there are still many good people in the world, and many people lend a helping hand.

　　In order to make his love action open and transparent, from the very beginning, he always sought one-on-one support from caring people or organizations for poor students, leaving contact information with each other. Except for a few poor families who don’t withdraw money or are handed over by their loved ones at their request, most of the subsidies are directly paid to the bank cards of poor students or their parents.

　　Funded student Xu MeimeiWhen I first entered the first year of high school, Mr. Huang began to support me (contact caring people). I am very grateful to Mr. Huang for helping me.

　　Supported student Yao ZhengchaoSometimes I feel that parents and relatives help us because of blood relationship, which seems to be an obligation, but in fact, these caring people who help me, whether they are sisters or aunts, I feel that their hearts are particularly touching me. Especially those like Mr. Huang, have been doing it all the time.

　　In 2006, Huang Jinlong retired as a teacher of Pujia Primary School in Jiuba Town, Tongzi County. However, the search for caring people for poor students has not stopped.

　　After 30 years’ continuous efforts in Huang Jinlong, he connected more than 1,000 poor students with caring people and organizations, and raised more than 1.5 million yuan in total, which enabled them to successfully complete their studies.

　　Jinlong HuangI am happy as soon as they are well, because they can stand out and change their destiny with knowledge. As long as they can finish their studies, study hard and go to work, my heart will be put down. Of course I’m happy.
