What is the ecological environment of the Three Gorges Reservoir area including climate pollution,

1. The migratory route of some fish, such as the Chinese sturgeon, has been cut off, but it is said that this migratory route has been cut off when Gezhouba was built, and the Three Gorges has only aggravated it. 2. The interception of the Three Gorges Dam led to a decrease in sediment in the estuary. Since the seventies and eighties of the last century, Shanghai's land area has been quietly "expanding", especially in the tidal flats.

Fifteen percent of Shanghai's land area was reclaimed by sediment accumulation in the Yangtze River. However, in the future, as the amount of sediment accumulation decreases, not only will Shanghai's "expansion" slow down, but even the existing area may be eroded by the sea. 3. It is said that it is also a very controversial point, that is, the Three Gorges Dam has improved the flood control standards downstream, but in fact, in recent years, you can see from the ** that the flood control standards of the Three Gorges have been lowered from once in 10,000 years to once in 100 years.

The Three Gorges Reservoir area has accumulated a large amount of water, and a very large amount of water will no longer come downstream, and the entire water cycle balance downstream will be broken. The decrease in the flow of water in the Yangtze River and the reduction of the water level in the lower reaches of the Yangtze River will inevitably lead to a drop in the groundwater level along the Yangtze River. When the amount of water vapor evaporation decreases, the air dries out, and the water vapor mass from the ocean is naturally overabsorbed as it passes through the lower reaches of the Yangtze River, so many places inland are likely to be inaccessible.

The air mass cannot reach the interior, which naturally affects the local rainfall. At the same time, due to the decrease in upstream water, the downstream Yangtze River channel often lacks water depth, which affects the passage of ships. 4. The Three Gorges Reservoir has a huge storage capacity and a huge amount of water storage, so it will inevitably increase the frequency of reservoirs in the reservoir area and even downstream.

Adjusting the local microclimate reduces the annual temperature difference, increases the water vapor content, and increases the probability of precipitation, which alleviates the urban heat island effect.

Beneficial effects: water storage and flood control capacity, regulating the uneven spatial and temporal division of water resources, bringing convenience to river transportation, power generation will improve energy consumption structure, environmental protection and emission reduction, improving agricultural irrigation conditions and water for daily life, air humidity, etc.

Unfavorable: Groundwater infiltration is strengthened, groundwater level rises, and the probability of geological disasters such as ** increases.

The impact on our climate is severe.

1. The Three Gorges water storage is in place, expanding the surface of the Gaoxia Lake from Chongqing to Yichang, and increasing the upward water vapor flow from the ground in this area, which hinders the southward movement of Siberian cold air and the northward movement of warm and humid Pacific air, which is important to China's climate, and the original climatic law balance is broken.

2. As a result, the northward advance of the Pacific Ocean warm and humid airflow in winter is blocked, and a large number of them are concentrated in southern central China, southern Chongqing, Guizhou, northern Guangxi, Hunan and Hubei land, northern Fujian, and most of western Zhejiang, resulting in an increase in the frequency of frost and snow disasters in this area in winter, while the north of Qinba Mountain, northern Sichuan, Henan, Shaanxi, and Gannan areas in China are significantly less than in winter because of the warm and humid airflow that can form rainfall, and the winter performance is high temperature and drought.

3. In summer, north of Qinba Mountain, northern Sichuan, Henan, Shaanxi, and Gannan regions in China, the cold air from the south of Siberia and the rising water vapor of the Three Gorges form a front to produce more rainfall, while drought occurs in Central China, South China, East China, Chongqing, and Guizhou during the same period.

4. In a state of drought, the Three Gorges is bound to open the sluice gates to release water, and as the lake shrinks, the rising water above it will decompress and sink for a short time, which will cause a strong convection opportunity for the cold air to the south and the warm and humid air flow to the north.
