Characteristics of Water Environment in Regions of zhaling and Eling lakes near Water head of Yellow river

摘要

Conditions of the water environment in the region of the zhaling and Eling lakes, which are loca- ted in the frozen earth zone on the Qingzang plateau, are unique. The equilibrium of the water quantity of the two lakes is maladjustment under the condition of a dry and cold climate in which evaporation is greater than precipitation. The Zhaling and Eling lakes have been atrophying, leaving three lake ter- races and star-studded lagoons around the two lakes since Holocene.
