What are the characteristics of Dongting Lake in China?

Dongting Lake is an important storage lake in the Yangtze River basin, with strong flood storage capacity. It has saved the Yangtze River floods many times, and Jianghan Plain and Wuhan three towns have been able to survive the floods safely.

Dongting Lake is an important strategic place in history and the birthplace of China traditional culture. There are many scenic spots in the lake area, and the historic site represented by Yueyang Tower is an important tourism cultural resource. It is also the birthplace of Chinese traditional agriculture, the famous land of plenty, the most important commodity grain and oil base and aquaculture base in Hunan Province and even the whole country.

Dongting Lake is a faulted basin on the Tainan axis of the Yangtze quasi-ground, which was formed in Yanshan movement and continued to Himalayan movement. Cretaceous is a period of basin development and expansion. Since the Quaternary, Dongting Lake depression basin has completely sunk again under the action of neotectonic movement and accepted sedimentation, becoming the area with the widest distribution, the largest thickness and the most complete sedimentary sequence in the Quaternary in Hunan Province. There have been more than four evolution processes of lake formation and land uplift, and the corresponding depressed basins disintegrated to form fault basins.
