摘要 本研究于2019年4月对独木河流域开展浮游生物调查及多样性分析。结果表明:该流域内浮游植物7门35属71种,优势种为小环藻、舟形藻、微小色球藻和衣藻;浮游动物3门26属36种,颈沟基合溞为绝对优势种。浮游植、动物的Shannon-Wiener多样性指数分别为3.84(3.45~4.22)、2.28(1.97~2.71),Pielou均匀度指数分别为0.88(0.81~0.91)、0.94(0.89~0.98)。独木河流域浮游生物群落结构较简单,水体呈富营养化趋势,水质处于清洁至β-中污染之间,这为该流域水生态环境及水生生物研究和保护提供了本底资料。 This study conducted a survey on plankton diversity in the Dumu River Basin in April 2019.The results showed that there were 71 species of phytoplankton belonged to 35 genera and 7 phyla in the watershed,and the dominant species were Cyclotella,Navicula,Chroococcus minutus and Chlamydomonas,respectively.Simultaneously,there were 36 species of zooplankton belonged to 26 genera and 3 phyla,and Bosminopsis deitersi Richard wasa dominant species.Moreover,the Shannon-Wiener diversity index were 3.84(3.45~4.22)and 2.28(1.97~2.71),respectively,and the Pielous evenness index were 0.88(0.81~0.91)and 0.94(0.89~0.98).The structure of the plankton community in the Dumu River Basin was relatively simple.However,the water quality was between clean and beta-medium pollution,and it showed a trend of eutrophication,which could provide essential data for the research and protection of aquatic ecological environment and aquatic biodiversity in the future.
