Community structure of phytoplankon and its relation with water quality in Xixi Wetland for the frist project aera, Hangzhou
摘要
Abstract
Studies on community structures of phytoplankon, including genus richness, density and biodiversities, and regression analysis between community index of phytoplankon and water quality parameters were carried out from Jan. to Dec. of 2007 in Xixi Wetland of the first project-circled aera, Hangzhon. 56 genus of algae were found, of which 73.21% were Chlorophyta and Bacillariophyta. The annual mean density of algae from Ⅰ station to Ⅳ station were 2.88×10~8, 0.37×10~8, 0.47×10~8 and 0.71×10~8 cells/L respectively, of which 93.76% were Chlorophyta and Cryptophyta, and the Chlorella, Cryptomonas and Chamydomonas were dominated in the algae community. The algae diversity indexes of Genus Marglef from Ⅰ station to Ⅳ station were 1.17, 1.10, 1.08 and 1.06 respectively. According to values of algae comprehensive index, Xixi Wetland has suffered serious pollution and can be regarded as eutrophication status. Logarithm density of algae was positively correlated with COD_(Mn) value in station Ⅰ and station Ⅲ (P< 0.01), and positively correlated with water conductivity value from Ⅰ station to Ⅳ station(P< 0.01).关键词
