和睦湿地浮游植物群落结构特征及环境因子分析
Phytoplankton Community Structure and its Relationships with Environmental Factors in Hemu Wetland
摘要
Abstract
Fifteen typical sampling sites were chosen to investigate the phytoplankton community structure and its relationships with the environmental variables in Hemu wetland between July ,2011 and April ,2012 .The study identified 101 species that belonged to 61 genera ,36 families ,20 orders and 8 phyla .Among the species ,Chlorophyta was the dominant class ,followed by Bacillariophyta and then Euglenophyta .The cell abundance of phytoplankton changed in the range of 17 .47 × 106 ~41 .55 × 106 ind ./L ,and the average cell abundance was 27 .99 × 106 ind ./L .The values of the Margelef index ,Pielou index ,Shannon index and Simpson index of the phytoplankton community were 0 .60~1 .68、0 .59~0 .81、1 .21~2 .51 and 0 .62~0 .86 ,respectively .Pearson correlation analysis and PCA analysis were used to indicate the relationships between environmental variables and the seasonal succession of phytoplankton community .The results showed that TN ,COD ,pH and temperature were the main dominant variables and contributed to the seasonal changes in the phytoplankton community .关键词
