The hottest Poyang Lake cries out for thirst. Thou

Poyang Lake is thirsty, and thousands of people are in danger: natural disaster or man-made disaster

with the arrival of early spring 2008, Poyang Lake, the largest freshwater lake in China, has reduced its water area from 4000 square kilometers to less than 50 square kilometers. Once the vast water surface with blue waves disappeared. According to statistics, tens of millions of people in the cities along the Poyang Lake suffered from the severe drought. Poyang Lake is thirsty. In addition to the irresistible factors such as the persistent drought along the lake area and the lack of upstream water since 2006, it seems that the man-made harm is even more terrible

building weirs around the lake can be seen everywhere

in the cold spring, Tan Gengen, an old fisherman in Duobao Township, Duchang County, Jiangxi Province, sat by the dry lake with a blank face. At the beginning of the year, I wanted to catch more fish and sell them at a good price, but after several times, there were only a few small fish. He said that in previous years, big fish could catch hundreds of kilograms a day. It was more difficult to catch fish year by year, and the income was also less year by year

the peak fishing season every year is August and September, and many fishermen collected it in August 2007. Tan Gensheng believes that the reason for the income is that the income from fishing is not enough to cover the expenses of the day, and many fishermen are ready to seek other businesses

when visiting the counties around Poyang Lake, many directors of the Fishery Bureau believed that the cofferdam cutting the lake was a major reason, and Poyang Lake was partitioned and dried up

illegal damming of Poyang Lake waters continues to occur, and a wave has formed in some places. Taking advantage of the exposure of the lake bottom in the dry season, some farmers built a 1-5 meter high Cofferdam at the bottom of Poyang Lake to enclose and occupy the waters of rivers and lakes. After the lake water gradually retreats in the dry season, the cofferdam owners reap the benefits

some cofferdams, which are more than 20 kilometers long and two to five meters high, occupy nearly 5000 mu of water. This was especially true at the end of 2006

Fu Qionghua, a member of the National Committee of the Chinese people's Political Consultative Conference, said that the essence of building a weir around Poyang Lake today is the same as that of building a farmland around the lake in those days. It is a single valve that eats the lake by the lake. In order to accurately judge whether the solenoid valve has a fault or not and whether it has a fault, try to avoid disassembly. First, remove the four hoses connecting the upper and lower collets, and connect them with each other to destroy the ecology. Illegal cofferdams not only destroy the competitiveness of the fishery market in the lake area and further improve resources, but also seriously affect the flood discharge on the lake. Measures must be taken to stop them as soon as possible

relevant aquatic scientific researchers also pointed out that this is illegal. Building weirs around the lake is a barbaric plunder of the wild fishery resources in Poyang Lake, which destroys the normal migration and reproduction of wild fish and the food source of migratory birds in Poyang Lake

fast growing poplar devours Poyang Lake Wetland

since 2000, in the wave of investment attraction, a poplar planting storm has swept 11 of the 12 counties and cities in Poyang Lake District, reaching 198300 mu. 11 counties and cities in Poyang Lake District have planted a large number of fast-growing poplar in Poyang Lake wetland through investment attraction. The more important reason for the rapid growth of poplar in wetland lies in the huge economic benefits it brings

the consequences of planting poplar soon became apparent. There are continuous Poplar Forests on the wetlands along the lake, with more poplar trees and significantly fewer birds. At that time, opposition began to appear. Experts pointed out that planting a large number of poplar trees would change the nature of the wetland, make the wetland dry, and be detrimental to the safe migration of migratory birds

some counties and cities in kehu district have a strong interest in attracting investment from foresters. Poyang Lake Nature Reserve Administration and other relevant departments have been raising objections. The Bureau found this problem in June 2004, and then reported it. The provincial forestry department and other departments specially sent a letter to the local government to prohibit the planting of poplar below 802 million tons and 8 meters of Wusong elevation 1 of Poyang Lake

in 2005, poplar planting was basically stopped in all regions, but it began to rebound in 2006

relevant experts pointed out that this behavior of planting poplar is a short-sighted behavior, which gains immediate benefits and damages the ecological environment of Poyang Lake

and the design of the carton meets the requirements; If the strength of the tested cartons fails to meet the safety and pressure resistance standard, disorderly sand mining intensifies lake bottom desertification

in the toad stone section of Poyang Lake, we see sand lifting boats, sand mining boats, and sand carriers, which block the surface of the Yangtze River, and some boats even invade the main channel of the Yangtze River. From Xingzi to Hukou waterway, countless sand dredgers shuttle by. Poyang Lake, once a vast expanse of blue water, was stirred into a pot of porridge. Passing the Hukou waterway for many times, you can see the scene of sand digging everywhere

according to the analysis of Poyang Lake fishery management personnel, sand dredgers generally first lift off a layer of fertile silt at the bottom of Poyang Lake, and then excavate the exposed sand and gravel. This layer of fertile silt is the breeding place for underwater microorganisms, including the main bait of fish. Sand excavation has aggravated the desertification at the bottom of Poyang Lake

disorderly sand mining and supervision in Poyang Lake have become a major persistent disease of Poyang Lake's resources and environment. It is learned that some governments along the lake have publicly auctioned the sand mining rights of the lake area for local interests, and there is a problem that they only charge money or are difficult to manage

it is understood that from 1998 to 2003, relevant departments in Jiangxi began to plan and harness Poyang Lake, and the situation was under control, but this disorder was not fundamentally curbed

Zhang Jilin, director of the Yugan County Fisheries Administration Branch in Jiangxi Province, believes that sand mining has had a great impact on the survival of fish. The sand sucking king has destroyed the entire riverbed, and the delicacies of fish such as snails and mussels in microorganisms have been sucked away. In addition, the site was destroyed, and there was no place for fish to spawn

according to the local fishery administration personnel, a large sand dredger with a power of several thousand horsepower can absorb all the sand and stones within a water depth of 30 meters and a radius of 60 meters in one operation, forming a 100 meter wide pit. Hundreds of sand dredgers shuttle on Poyang Lake, and the motor sound keeps ringing day and night

Wang Xinggan, director of the Poyang County Fisheries Branch of Jiangxi Province, also believes that disorderly sand mining does great damage to the growth environment of fish

with fewer fish, there was an embarrassment of people and birds competing for food by the lake. When fishermen frantically catch only the remaining fry for their livelihood, the migratory birds on the bank also have no food to find. At the edge of Poyang Lake, a large number of lakeside wetlands have completely dried up, even cracked and hardened. Some lakes are full of enchantment arrays, a special fishing tool. As long as you enter, the fry cannot escape

if there are no fish and migratory birds, the ecological food chain of the wetland will be interrupted. Within a few years, Poyang Lake, the largest freshwater lake in China, will disappear. A staff member of the Poyang Lake National Nature Reserve Administration was worried

if sand mining is one of the major reasons why lakes are affected, the balanced development of the ecological chain cannot be ignored. In an interview, director Chen of Jiangxi Wetland Management Center said that in the face of natural disasters, man-made disasters are the most terrible, and we need to work together to protect this ecological chain. To protect this ecological chain is to protect ourselves
