Environmental Benefit of Three Gorges Project
Three Gorges project will not only produce huge economic benefit, but also play great role in improving the ecological environment of Yangtze River areas.

First Target of Three Gorges Project is Flood Control.

The project can effectively adjust the upstream flood of Yangtze River, which will assure a flood control standard of the Jingjiang section, a downstream reach to Three Gorges of Yangtze River, arise from currently preventing 10-year flood to controlling 100-year flood. Even in case of a rare occurrence of 1000-year flood, mass damages or injuries can still be prevented. At the same time, social problems such as environmental deterioration and epidemics related to the flood or flood diversion can also be avoided. Thus the project will protect 1.5 million hectare of farmland and towns, and 15 million of people from flood damage at Jianghan Plain and Dongting Lake area. And also the project will raise the reliability of flood control in the mid and lower reach of Yangtze River, relieve the sand silt of Dongting Lake and create favorable conditions for dredge of the lake, and prevention and cure of the schistosomiasis epidemics in the lake area.

Three Gorges Power Plant will Provide Clean Energy.

Compared to the coal-fired power stations with equivalent electricity generation, Three Gorges Power Plant will decrease emission of 100 million tons of CO2, 2 million tons of SO2, 0.37 million tons of nitrogen oxide and a lot of waste water and solid waste. It will bring a great benign influence in improvement of environment, especially preventing acid rain and greenhouse effect in East and Central China.

Other Benefit of T hree Gorges Project

The Three Gorges reservoir, after the project is completed, will improve the weather in this area, be favorable for agriculture, and improve water quality in the mid and lower reach, which will relieve the invasion of saline tide in the river's mouth to East China Sea.
