Correlation Analysis of Spring Phytoplankton Community and Environmental Factors in Hazihu Lake
摘要
Abstract
Community structure of phytoplankton and the associated environmental factors were investigated in Haiz -ihu, Changhu Lake in the spring of 2012, and their relationship was also analyzed by canonical correspondence a-nalysis(CCA).Results showed that 93 species of phytoplankton were identified , among which Chlorophyta accoun-ted for 46.76%, followed by Bacillariophyta (22.65%)and Cyanophyta (15.00%).There were 6 dominant spe-cies and the most dominant species was Chlorella vulgaris with the dominance index of 0.36.The phytoplankton a-bundance ranged from 86.21 ×105 to 410.12 ×105 cells/L with the average value of 232.85 ×105 cells/L.Biodi-versity index and evenness index were 1.82-3.28 and 0.40-0.63, respectively.As a result, the water in Haiz-ihu was in a state of severe eutrophication according to the level of phytoplankton abundance , as well as the degree of dominance and the diversity index .Canonical correlation analysis ( CCA) suggested that NO 3-N, COD, Chl.a, PO4-P were the main environmental factors which affected the spatial distribution of phytoplankton community , meanwhile , geographical feature , human activities and hydrodynamic features were also the important influencing factors.关键词
