摘　　要：2008年至2009年对贵州红枫湖(HF)、百花湖(BH)、阿哈水库(AH)的桡足类和枝角类动物进行4次采样调查,共发现桡足类5科11属19种,其种包含一未定种。枝角类5科9属14种。三个水库中都存在的桡足类优势种为绿色近剑水蚤、叶片剑水蚤、短尾温剑水蚤;枝角类的优势种为长刺溞、长额象鼻溞;角突网汶溞。桡足类和枝角类的总密度在红枫湖为春季最高,秋季次之,夏季最低;在百花湖为夏季最高,秋季次之,冬季最低;在阿哈水库为春季最高,秋季次之,夏季最低。三个水库季节生物多样性比较:春季的多样性是AH>BH>HF;夏季和冬季是BH>AH>HF;秋季是AH>HF>BH。季节性气候变化和污染是影响桡足类和枝角类动物群落变化的重要因素。Copepida and cladocera community is investigated for four times in the Hongfeng, the Baihua and the Aha lakes from 2008 to 2009. It is found that the copepod consists of 5 families, 11 genera, 19 species with one species is not identified and the cladocera consists of 5 families, 9 genera, and 14 species. Dominant species of copepoda are T.prasinus（Fischer）, C.uicinus lobosus Kiefer and T.breuifurcatus Harada. Dominant species of cladocera are D.longispina（O.F.M.）, C.cornuta Sars and B.longirostris（O.F.Müller） in all lakes. Total density of copepoda and cladocera is highest in spring, lower in autumn, lowest in summer in both the Hongfeng and the Aha lakes; the highest in summer, lower in autumn, lowest in winter in the Baihua lake. Seasonal biodiversity ordering ranks as AH〉BH〉HF in spring, BH〉AH〉HF in summer and winter, and AH〉HF〉BH in autumn. Seasonal weather change and pollution is important factor affecting copepida and cladocera community change.
