Abstract
Donghu Lake in Wuhan is a multipurpose complex water body. However, its eutrophication phenomenon becomes increasingly serious. By making use of detailed and accurate contamination monitoring data and several mathematics models, we probe into the dynamic state of water quality. The year’s average value of major contamination index in Donghu Lake from 2001 to 2008 and fuzzy complex index are used to assess its short-term state of water quality. The results show that its water quality is basically stable in the 4th class of water quality standard GB3838-2002.

The increase in resident population, and the rapid development of high-tech industries surrounding the lake have resulted in deterioration in water quality in Donghu Lake, serious eutrophication phenomenon, increasing degree of water pollution, aquatic ecosystem structure and function disorders and inverse succession, which affects people’s lives and health
