[Objective] The aim was to explore effects of environmental factors on the content of Chlorophyll a in ShaHu Lake. [Method] Based on the data in Shahu Lake from November in 2007 to September in 2008, the relationship between chlorophyll a and environmental factors like water temperature, pH, secchi-depth (SD), total nitrogen, total phosphorus and potassium permanganate index was studied by grey relational analysis method. [Result] The main environmental factors affecting the content of Chlorophyll a in ShaHu Lake were in order of water temperature potassium permanganate index total nitrogen pH total phosphorus SD. [Conclusion] The research provides reference for the control of eutrophication and the reasonable development and utilization of Shahu Lake.
