摘 要: | The majority of lakes in the eastern part of China are shallow and in various stages of decaying.Chaohu Lake is a typical example and was chosen as a case study in the Cooperative Ecological Research Project(CERP).Through various observations and sample analyses,the environmental impact of heavy nutrient load was assessed,and a multi-dimensional picture of the eutrophication state was obtained.Chaohu Lake is in hypertrophk state and has many typical symptoms:high concentrations ofphosphorus and nitrogen,frecluent algal bloom,dominance of bluegrecn algae,high content of chlorophyll-a,low Secehi Disk depth and abnormal siltation of the lake.The lake pollution is still developing and in recent years has affected the city water supply and the regional economy.
