The reason for the high salinity of Lake Dabusu

The water salinity of Dabusu Lake is high. On the one hand, it is due to the influx of sodium ions from the surface runoff from all sides, and the sodium ion content in the lake increases. On the other hand, it is due to the hot climate, strong wind and strong evaporation. , causing the lake water to evaporate quickly, the lake water to decrease, and bicarbonate of calcium carbonate and sodium magnesium bicarbonate to form water in the lake. Dabusu Lake

Dabusu Lake is located southwest of Qian'an County, Jilin Province, in the center of the western subsidence zone of Songliao Plain. The total area of ​​Dabusu Lake is 56 square kilometers.

The water storage capacity of Dabusu Lake is 603.27 million cubic meters. During the wet season, the water depth of Dabusu Lake can reach 1.5 meters, but during the dry season, the water depth is only 0.5 meters.

Dabusu Lake was a freshwater lake in the early days, but in the late Holocene, the fresh water in Dabusu Lake changed to alkaline water. The reason for the change was not only topographic factors, but also climatic factors.
