Gerencuo is a lake in Shenzha County, Xizang Autonomous Region. Ge Rencuo (Tibetan:? Willie: ske ring mtsho, Thl: Keringtso) is located in Shenzha County, Naqu Prefecture, Tibet, in the west of Shenzha County, at the northern foot of Gangdise Mountain and at the southern foot of Kangbaduoqin Mountain. The lake is 4650 meters above sea level and covers an area of 475.9 square kilometers.
The shape of the lake is a northeast-southwest strip. The lake water is mainly supplied by Shenzha Zangbo on the southeast coast and Balu Zangbo on the southwest coast, and the lake water is injected into Zigui Cuo through Xiajia Zangbo on the northwest coast. The lake area belongs to the semi-arid climate of alpine grassland, with an average annual precipitation of about 200 ~ 300mm and an average annual temperature of 0℃.
Saltwater lake, as its name implies, refers to a lake that accumulates on the surface in the form of salt water. The existence of saltwater lake needs certain geological and climatic conditions. First of all, there is a basin that collects water to form a lake in the internal flowing basin.
Secondly, the evaporation of the lake exceeds the recharge, and the lake needs to have a certain inflow. Because there is no surface runoff in extremely arid areas, lakes cannot be formed, so semi-arid and semi-humid areas are most conducive to the formation of saline lakes; Finally, the inflow of river water or wind brings a large amount of salt in the surrounding rock into the lake, which makes it possible for salt to accumulate.
Due to the special formation conditions, most of the salt lakes in China are distributed in the Qinghai-Tibet region. Salt lake is a kind of saltwater lake, which is the product of the development of the lake into old age. Its salinity is very high, often more than 35 g/L.
