摘　　要：2011年3月对夜郎湖水库后生浮游动物及水质情况进行了调查。共鉴定出后生浮游动物17种,其中,桡足类2种,枝角类3种,轮虫类12种。优势种为针簇多肢轮虫（Polyarthra trigla Ehrenberg）、矩形龟甲轮虫（Keratella quadrata（Müller））、螺形龟甲轮虫（Keratella cochlearis Gosse）、曲腿龟甲轮虫（Keratella valga Ehrenberg）、透明溞（Daphnia hyalina Leydig）、长额象鼻溞（Bosmina longirostris（O.F.Müller））和近邻剑水蚤（Cyclops vicinus Uijanin）。后生浮游动物数量为0.2~570.0 ind/L。利用后生浮游动物群落结构、理化指标及生物多样性指数进行综合评价,该水库水质为Ⅰ类。Meta-zooplankton in Yelanghu reservoir was investigated;and the water quality was assessed in March 2011.The results indicated that 17 species of meta-zooplanktons were identified,consisting of 12 species of Rotifera,2 Species of Cladocera,and 3 species of Copepoda.The dominant species were Cyclops vicinus Uijanin,Daphnia hyalina Leydig,Bosmina longirostris（O.F.Müller）,K.quadrata（Müller）,K.cochlearis Gosse,Keratella valga Ehrenberg and Polyarthra trigla Ehrenberg.The abundance of meta-zooplankton ranged from 0.2 to 570.0 ind/L.The community structure of meta-zooplankton,physical and chemical indicators and diversity indexes were used to evaluate the water quality;and it was revealed that the water quality belonged to classⅠ.
