| 中文摘要: |
| 为了对三峡库区26条主要河流及长江干流浮游甲壳动物群落结构进行调查，2010年4月至2011年6月分四次对三峡库区主要河流进行浮游甲壳类进行定量和定性采集标本。152个采样点四次采样共鉴定出浮游甲壳动物50种，其中枝角类36种，桡足类14种。浮游甲壳类主要是以常见的广温性种类为主，四次调查中发现的种类均为长江流域常见种。三峡库区浮游甲壳类动物具有明显的季节性变化特征，四月份（春夏季）的存量和种类明显高于十月份（秋冬季）；也具有明显的纵向分布特征，相同支流上游的存量和种类一般低于回水区的数值。 |

| In order to investigate the crustacean zooplankton community structure of the major tributaries in Three Gorges Reservoir Area(TGRA)，four times samplings in 26 tributaries of TGAR were carried out from April 2010 to June 2011. 152 samples were identified and 50 species were collected，including 34 species of cladocera，and 16 species of copepod. The major species of the crustacean zooplankton could live in the wide temperature. And all of species were common in Yangtze River. Species composition，distribution and density of planktonic crustacean showed significant seasonal and spatial variations. The densities and species numbers in Spring were higher than those in Winter obviously. The densities and species numbers in upstream of tributaries were generally lower than those in back water region. |
