What are the advantages and disadvantages of the Three Gorges Dam?

1 to solve the power shortage problem in China.

After the completion of the Three Gorges Dam, it can provide 654.38+000 billion kWh of power generation every year, which provides the impetus for the rapid economic growth of China. It provides lighting for countless families, otherwise, there will be power outages for three days and two days as before.

2. Excellent flood control capability.

After the completion of the Three Gorges Dam, the reservoir water level can be effectively regulated. When the downstream area needs water, the water flow can be increased. When there is a flood danger downstream, the downstream water flow in the reservoir area can be controlled.

3. Promote local economic development.

After the completion of the Three Gorges Dam, it has become a 5A-level scenic spot. Every year, a large number of tourists visit the Three Gorges Dam, creating many employment opportunities and increasing economic benefits.

Construction significance

1. The Three Gorges Project is by far the most comprehensive water conservancy control project in the world, which is exerting great flood control benefits and shipping benefits. After the completion of the Three Gorges Dam, a 600-kilometer-long reservoir will be formed, which will store water in stages and become a rare new landscape in the world.

2. After the project is completed, the normal water level of the reservoir is1.75m, the flood control capacity is 2.21.50 billion cubic meters, and the total storage capacity is 39.3 billion cubic meters, which can give full play to its key role in the flood control system in the middle and lower reaches of the Yangtze River, and will significantly improve the 660km waterway from Yichang to Chongqing, with a fleet of 10,000-ton ships reaching Chongqing Port directly.
