在2014年春季（4月份）、夏季（7月份）、秋季（9月份），对宁夏沙湖8个采样点进行了采样调查。对沙湖浮游动物的种类组成、群落结构及物种的多样性进行了研究。调查中共鉴定出浮游动物31种，其中轮虫的种类最多，为13种，占总数的42％；桡足类为8种，占总数的26％；原生动物为7种；枝角类共鉴定出3种。在3次采样中，桡足类优势种最多，分别为英勇剑水蚤（Cyclops strenuuss）、广布中剑水蚤（Mesocyclops leuckarti）、无节幼体、透明温剑水蚤（ Thermocyclops hyalinus）、爪哇小剑水蚤（ Microcyclops javanus）。分析了不同样点浮游动物的群落多样性特征。夏季各样点群落组成的相异性最大，春季相异性最小。采用Shannon－Weaver指数（ H′）和Pielou均匀度指数（ J）评价水质，生物多样性指数最高的站点是7＃，最低的是8＃，水质的综合评价结果均为中度污染。

We studied the community structure and diversity of zooplankton in Sha Lake , Ningxia Province , in April, July and September 2014.We identified 31 zooplankton species totally , among which 13 Rotifera as predominant species accounting for 42%, 8 Copepoda accounting for 26%, 7 species of protozoan , and 3 species of protozoon .The Cladocera was the most dominant species including Cyclops trenuuss, Mesocyclops leuckarti, Naupil i, Thermocyclops hyalinus and Microcyclops ja-vanus after three surveys .We analyzed the diversity of zooplankton at different sampling sites .The dissimilarities of commu-nity composition were the highest in winter and the lowest in spring .We used Shannon-Weiner index and Pielou index to eval-uate the water quality, the highest biodiversity index was 7#, and the lowest was 8#among the sampling sites , and the com-prehensive evaluation of water quality was moderate polluted .
