Abstract

A lake wetland is the production of humans and nature. It has the functions of a natural lake wetland and an artificial reservoir. Lake wetland ecosystem health is an important symbol of humans and nature harmoniously using water. The study of water quantity threshold is important to the management of a lake wetland. Therefore, this paper explores the calculation method of water quality threshold value of protection of lake wetland ecosystem health from two aspects of non-biological and biological water which are formed by a lake, using Xinghai Lake as an example and using methods of water balance and minimum water level. Finally, the threshold value of water supply is 2462.35 million m3 and the minimum water requirement is 2778 million m3. Water quality requirements must be better than Class III.
