What is the function of the Three Gorges Project?

There are frequent floods in the upper reaches of the Yangtze River and its tributaries. Every time a serious flood occurs, the Jingzhou section of the Yangtze River (Jingjiang River) below Yichang should take flood diversion measures to ensure the safety of Wuhan.

Step 2 generate electricity

The economic benefits of the Three Gorges Project are mainly reflected in power generation. This project is a giant power supply point in the middle line of china xd East Power Transmission Project, and the power generated will be mainly sold to Hubei, Henan, Hunan, Jiangxi and Chongqing in Central China Power Grid.

3. Ships

Before the impoundment of the Three Gorges, the annual one-way traffic volume of Chuanjiang River was only 6.5438+million tons, and 10,000-ton ships could not reach Chongqing at all. The Three Gorges Project ended the history that "Sichuan has never sailed at night since ancient times". Through several impoundments of the Three Gorges, the navigation conditions of the Sichuan River have been improved day by day.

Impact of the Three Gorges Project:

Environmental effect

The environmental impact of the Three Gorges Project comes from reservoir pollution. Sewage and domestic garbage discharged by towns and tourists on both sides of the Three Gorges are directly discharged into the Yangtze River without treatment. After water storage, because the water flow is still, pollutants can't flow down in time and accumulate in the reservoir, which causes water quality deterioration and garbage floating, and may cause infectious diseases. Some towns collect domestic water from other sources, and at the same time, a large number of immigrants reclaim wasteland, which also aggravates water pollution and causes soil erosion.

Humanistic influence

After the impoundment of the reservoir, the canyon feeling of the Three Gorges will be weakened, and the surrounding area of the Three Gorges was the intersection of Ba culture and Chu culture in ancient times. More than 200 cultural relics/kloc-0 have been found in the flooded area of the reservoir. Since 1992, the cultural relics department has started to carry out rescue excavation, and it is expected to complete rescue protection before water storage in 2009.
