What water control projects have been built in the Yangtze River Basin?

Yangtze Three Gorges Water Control Project.

The largest water control project on the main stream of the Yangtze River is the Three Gorges Project, which is located at the junction of the second and third steps. The Three Gorges Project, referred to as the Three Gorges Project for short, is a large-scale water conservancy project in the middle and upper reaches of the Yangtze River in China, the largest hydropower station in the world and the largest project in China.

Distributed in the main stream of the Yangtze River from Chongqing, China to Yichang, Hubei. The dam is located in Sandouping, Yiling District, Yichang City, in the Xiling Gorge of the Three Gorges, and forms a cascade dispatching power station with Gezhouba Hydropower Station not far downstream. It is the largest hydropower station in the world and the largest engineering project in China.

Impact on ecology and environment.

The impact of the Three Gorges Reservoir on the ecological environment mainly includes two aspects. The beneficial effects are mainly in the middle reaches of the Yangtze River, including reducing the damage of floods to the ecological environment, reducing the pollution of coal burning to the environment and reducing the siltation of Dongting Lake. The adverse effects are mainly in the reservoir area. In addition to flooding cultivated land, changing landscape, and mass migration, it also affects rare species, weather, reservoir bottom floods, landslides, earthquakes, terrestrial plants and so on.
