| 摘 要： | 对三峡库区重庆段干流4个断面和支流2个断面的浮游动物群落结构、种类组成进行了初步调查。调查发现,浮游动物112种,其中原生动物36种,占总种数的32.14%;轮虫30种,占总种数的26.79%;节肢动物46种,占总种数的41.07%。浮游动物密度和数量均为支流大于干流。利用香农-威纳指数评价了水质状况,Shannon-Wiener多样性指数值范围在2.65~3.12,支流污染程度大于干流。

| Abstract: | The community construction and species of zooplankton from Three Gorges reservior in Chongqing zone was investigated from April to May in 2003.The results show that there are 112 species of zooplankton in Three Gorges reservior of Chongqing zone and the species of protozoan,rotifera and arthropoda are 36(32.14%),30(26.79%) and 46(41.07%) respectively.The density and amount of zooplankton in the tributaries is higher than that in the mainstreams.The pollution degree of tributaries is more serious than the mainstreams by the Shannon-Wiener evaluation method. |
