Reasons for the formation of Qinghai Lake:

Qinghai Lake is the largest inland saltwater lake in China and an important water body for maintaining the ecological security in the northeast of Qinghai-Tibet Plateau. Located in the northeast of Qinghai-Tibet Plateau and in Qinghai Province, it is the largest inland lake in China. The tectonic fault of Qinghai Lake has depressed the lake, and the edge of the lake basin is mostly connected with the surrounding mountains by faults. At the early stage of lake formation, 211 ~ 2 million years ago, it was originally a large fresh water lake, which was connected with the Yellow River system. At that time, the climate was mild and rainy, and the lake was discharged into the Yellow River through the Daotang River in the southeast, which was an outflow lake.

Up to 1.3 million years ago, due to neotectonic movement, the surrounding mountains rose strongly. From the end of Pliocene, Sun Moon Mountain and Bison Mountain in the east of the lake rose rapidly, which blocked the Daotang River, forcing it to flow into Qinghai Lake from east to west, resulting in Gahai and Erhai, and then separated into sub-lakes such as Haiyan Lake and Shadao Lake.
