The long-term drought has led to a rapid drop in the water level of Poyang Lake, the drying up of the riverbed, the serious degradation of the surrounding grassland, and the great impact on agricultural irrigation, which has also caused irreparable damage to the Poyang Lake ecosystem.
The average precipitation in Jiangxi is about 30% less than normal, and the water level of lakes in Jiangxi is generally lower than normal, and the water quality of lakes has deteriorated sharply. The deterioration of the ecological environment of Poyang Lake is more serious than that of the same period in previous years, and a large number of fish in Poyang Lake have died. It is reported that the drought has brought extinction to the local aquatic life in Poyang Lake, and a large number of aquatic life is waiting for rescue in the dry lake.
The water area of Poyang Lake stopped falling and rebounded.
On October 17, 2012, local authorities issued a statement saying that after three months of continuous drought, the water area of Poyang Lake had stopped falling and rebounded. The water level of Xingzi Station, the landmark hydrological station of Poyang Lake, is meters, and the water body of Tongjiang River in the lake area is 301 square kilometers. At present, it seems that the local ecological environment has been effectively improved.
The reasons for the deterioration of the ecological environment of Poyang Lake.
Global warming is the main environmental problem faced by human society today, which is mainly manifested in the increase of carbon dioxide in the atmosphere and the concentration of CO2 in the atmosphere, thereby increasing the greenhouse effect. and contribute to an increase in global temperatures. Due to the influence of human activities, the soil in the Poyang Lake area has been damaged to a certain extent. In addition, some human activities will also have a certain impact on the water quality of Poyang Lake, such as a large number of fish deaths in the lake, and the pollution of other pollutants will have a certain impact on the water quality, which will eventually lead to the deterioration of the water environment and the imbalance of ecological balance in the waters of Poyang Lake, resulting in a sudden climate change in the Poyang Lake area.
With the deterioration of the ecological environment of Poyang Lake, a large number of fish have died in Poyang Lake, which has had a positive impact on the aquaculture industry. According to incomplete statistics, the area of Pohu Lake in Jiangxi Province has decreased by about 1 3, accounting for about 1 3 of the total area of lakes in the country. Aquaculture in the Poyang Lake area not only causes economic losses, but also directly affects the normal life of residents.
-
It will cause local ecological imbalance. So the impact of drought on the overall environment is still very large, but fortunately, this phenomenon has been alleviated a lot.
-
It may cause the death or even extinction of some organisms in the water, thus affecting the entire biological chain.

Poyang Lake is the first freshwater lake in China, which has a role in regulating water level, conserving water sources, regulating local climate and maintaining ecological balance. Under the high temperature conditions this year, the former Poyang Lake is in a state of dryness and has entered the dry period ahead of schedule. Poyang Lake has shrunk by nearly 7% in January, what impact will it have on the local ecological environment?
First, the amount of water in Poyang Lake has decreased, the local climate has been affected, the temperature has risen, and the living environment is difficult to survive.
Water sources play a role in regulating local climate, and Poyang Lake, as the first freshwater lake in China, also has a certain positive effect on climate regulation. With the decrease in the amount of water in Poyang Lake, the local climate has also been affected to a certain extent, the temperature continues to rise, and the daily life of residents has also been greatly affected.
Second, the reduction of water levels affects local biodiversity, and fish stocks are starved of water, resulting in no fish to catch.
Poyang Lake is the largest freshwater lake in China, and at the same time, the fishery resources are also quite abundant, Poyang Lake is extremely famous for its shrimp and crabs, and the reduction of water level may affect the sharp decline of local biodiversity. As the water level continues to decline, the lack of water and oxygen for fish may lead to no fish to catch in the fishing machine, the reduction of fishery resources, and the income of residents will also be affected to a certain extent.
Third, the water level drops, affecting the local ecological environment, and migratory birds may have no food to eat in winter.
Spring goes to autumn, cold comes to summer, is an unchanging natural law, and the water level drops, may have an impact on the local ecological environment, fish and shrimp are difficult to survive, trees are difficult to grow, and wait until winter migratory birds may have nowhere to take refuge from the cold, may also cause no food to eat. Therefore, the change of water resources has a huge impact not only on human beings, but also on animals and plants, which affects the whole body.
Water resources are indispensable for our survival, so in our daily life, we must develop a good habit of saving water, and in the face of such a severe environment in the hot summer, we should cherish water.

Poyang Lake "shrunk" by nearly 7% in January, and the riverbed became "grassland". Poyang Lake is one of the four major freshwater lakes in China, and Poyang Lake has a huge wetland area. It stores a large amount of fresh water every year, and there are also a large number of plants and fish living in Poyang Lake.
-
It will have a very big impact on the local ecological environment, and not only has a bad impact on the ecological environment, but also has a very bad impact on the local economy and crops.
-
Severe blows to the local ecological environment may lead to the loss of local biodiversity and affect people's daily lives.

Poyang Lake is the largest freshwater lake in China, and the lake is vast. The lake roughly stretches from Sanyang in the south, to the mouth of the river in the north, to Wucheng in the west, and to Boyang in the east. It is 123 kilometers long from north to south, 23 kilometers wide from east to west, and has a circumference of about 433 kilometers.
With a maximum depth of 14 meters and a surface area of about 5,675 square kilometers during normal water periods, it is the largest freshwater lake in China. Located on the south bank of the Yangtze River, Poyang Lake resembles a giant gourd and is connected to the Yangtze River ring. It is bounded by Songmen Mountain between Duchang and Museong, and can be divided into two lakes.
On the shore of the North Lake Mountain, the water is very narrow, it is a narrow river channel, and the South Lake is wide and boundless, and the endless blue waves are like endless green satin covering the sky, which is the main body of Poyang Lake.
The waters here are vast, the lake is flat, the lake is rich in fish and shrimp, and the rice along the shore is full of fragrance. As early as the beginning of the 6th century A.D., the Poyang Lake area has been "reclaimed for fertile fields" and has become an important grain area in the Southern Dynasties. Poyang Lake feeds the people of Jiangxi with its abundant milk.
Poyang Lake is also a buffer zone for flooding in the middle reaches of the Yangtze River. Its water volume can reach 12.3 billion cubic meters, which is almost equivalent to the water volume of four Liujiaxia reservoirs, and is the largest "natural reservoir" in China. In addition to playing cards in the park for entertainment, there are also a large number of anglers who flock to Poyang Lake to fish.
Anglers move around the lake, accompanied by the sounds of cars and people. These can destroy the habitat of migratory birds. The garbage left behind by anglers poses a threat to the ecology of the lake.
Every time I go to the lake, I pick up used fishing nets and plastic waste, reminding anglers to take their trash with them when they leave. Zhan Zaolong is an old fisherman on Poyang Lake. After the ban on fishing, he became part of the finless porpoise rescue team, patrolling the lake every day.
Now, rescuing stranded or injured finless porpoises, reminding anglers to stay away from protected waters, has become his main job. He is also concerned that too many anglers could harm areas where finless porpoises congregate. The city of Lushan and Huhu County on the shores of Poyang Lake are carrying out special conservation actions to prevent tourists and vehicles from damaging the wetlands.
The relevant departments of Lushan City have set up blocking piles and warning signs at the intersection of the observation deck leading to Luoxingtun. The Lushan Forestry Bureau recently issued a recommendation calling for banning motor vehicles from entering the Poyang Lake wetland and severely punishing illegal acts of destroying the wetland.
-
It will directly affect the local ecological environment, and will lead to the drying up of water sources, the death of organisms, resulting in the local plants not growing normally, and there will be a lack of water sources**.
-
As a result, their lakes will become less and less water, some agriculture and food will be reduced, and people's drinking water will be limited.
-
Drought will definitely affect the balance of the ecological environment, first of all, it will have a certain impact on the destruction of the ecological environment.
-
Drought may damage the local ecological environment and affect the local ecological balance.

In the past 20 years, the large reduction in the wetland area of Poyang Lake is due to natural causes: sediments fill the lake and swamps; Global warming, climate warming and drying. Human causes:
soil erosion, which leads to large deposits of sediment; The reclamation of lakes and seas has led to the reduction of the area of lakes and coastal tidal flats. environmental pollution, leading to eutrophication of water bodies; Diversion of water for irrigation, the direction of the river, leads to a decrease in the amount of water.
The average annual siltation of Poyang Lake is about 100 million m3, and the sediment sedimentation rate is 54%. Obviously, the increasing sediment accumulation is an important reason for the shrinkage of wetlands and the decay of water regulation function.
The Poyang Lake Wetland is flat, vast and fertile. However, in order to expand the area of cultivated land, blind and unlimited reclamation and reclamation of wetlands have led to the large-scale loss of natural wetlands, and consequently the loss of wetland biodiversity and ecological functions.
In addition to the impact of dry climate and decreasing precipitation, the most direct reason for the water shortage in the Poyang Lake wetland is that the water storage and diversion projects built in the upper reaches of the river and the embankment projects along the river have cut off the hydraulic connection between the river and the floodplain swamp.
Pollutants brought in by runoff from the lake area, precipitation and dust reduction from the atmosphere on the lake surface, breeding bait and sewage discharge from ships traveling in the lake. Large-scale pollution and deterioration of the Poyang Lake wetland.
-
1. People continue to build fields around the lake.
2. Fish cage farming reduces the speed of water flow and increases sediment accumulation.
3. The upstream water is decreasing, which reduces the impact of sediment. 4. The most fundamental reason is man-made.

Since July this year, Poyang Lake has entered a dry period, and the water level of Poyang Lake has been declining due to the continuous hot weather. The drop in the water level of Poyang Lake has also attracted the attention of many professionals in the field, and everyone is worried about the current situation of Poyang Lake. After all, Poyang Lake is also the largest freshwater lake in China, which is of great significance to China.
In addition, the drop in the water level of Poyang Lake will also have a great impact on the domestic water supply of nearby residents, and if Poyang Lake dries up, it will affect the development of many aspects.
After October, the Jiangxi Ecological Meteorological Center finally brought good news to everyone, according to monitoring, Poyang Lake has rebounded to 105 square meters of water area. This is very good news for Poyang Lake, which has been declining in water levels. It also relieved nearby residents and local professionals, after all, the drought situation in Poyang Lake has been going on for a long time.
However, the rise in water levels does not mean the end of the drought period, and it is understood that the main reason for the rise in water levels is the remedial work of the upstream Three Gorges Dam to remediate the Poyang Lake. Although the water level has increased visibly a lot, this method is only a "palliative, not a cure". If you want Poyang Lake to really get out of the drought period, you still have to wait for the temperature to drop and there will be heavy rain.
The dry period in Poyang Lake should continue until November, and it rarely rains in the Poyang Lake area due to the cold air. In addition, due to the influence of sea pressure in the Poyang Lake area, there is still little rainfall in late October. The Jiangxi Meteorological Bureau released a report that Jiangxi will continue to have sunny days, and the temperature will gradually rise.
According to experts' speculation about the drought situation in Poyang Lake, the drought in Poyang Lake may last until November. This year's drought in Jiangxi is a huge test for Poyang Lake, and many people are worried about whether Poyang Lake will be able to survive. The water level of Poyang Lake continues to decrease, which has a huge impact on farmland irrigation, production and life.
Migratory birds in Poyang Lake include white cranes, white-headed cranes, black storks, and Baer's Pochard. >>>More
