Abstract: In three typical waters——the purfication waters,the aquaculture waters,and the Pro village waters,in Baiyangdian Lake,from April to November in 2013,the phytoplankton was investigated,the community structure characteristics were compared and the water quality was evaluated,using phytoplankton ecological index and water quality factors to evaluate the water quality.The results showed:the first dominant group was Chlorophyta in the three typical waters in Baiyangdian Lake,the second dominant group was Bacillariophyta in both the purfication waters and the aquaculture waters, but was Cyanophyta in the Pro village waters;the purfication waters was in the mesotrophic position,the aquaculture waters was in the eutrophic position,the Pro village waters was in the eutrophic position.In the purfication waters,the relationship between Bacillariophyta distribution and environmental factors was complex,the distribution of Chlorophyta was correlated with total phosphorus,total nitrogen,pH and dissolved oxygen.In the aquaculture waters,the distribution of Bacillariophyta was related to total phosphorus and total nitrogen,the growth of Cyanobacteria was inhibited by nitrogen and phosphorus.In the Pro village waters,the distribution of Cyanobacteria had a high correlation with nitrogen and phosphorus,the distribution of Bacillariophyta- was related to pH,temperature and total phosphorus.As a result of redundancy analysis(RDA),phytoplankton distribution was significantly affected by environmental factors in the three typical waters in Baiyangdian Lake.
