| 摘 要： | 基于2006年4月至2006年12月对白洋淀浮游甲壳动物进行采样调查，分析了白洋淀浮游甲壳动物的群落结构及多样性。本次调查共记录到浮游甲壳动物34种，隶属于9科19属，其中枝角类（Cladocera）19种，桡足类（Copepoda）16种。物种多样性季节性明显：枝角类优势种在春、夏和秋冬季依次为微型裸腹溞（Moina micrura）、长额象鼻溞（Bosmina longirostris）、长肢秀体溞（Diaphanosoma leuch）；而桡足类优势种在冬春季为英勇剑水蚤（Cyclopidae strenuus），在夏秋季为锯缘真剑水蚤（Eucyclopinae macruroides）和台湾温剑水蚤（Thermocyclops tsihokurnsis）。物种多样性春秋季较高，夏季和冬季较低。浮游甲壳类个体密度以春季最高，冬季最低。根据生物多样性指数综合判定白洋淀的水质为中营养化水平。

| Abstract: | Based on the crustacean zooplankton survey from April to December 2006 in Lake Baiyangdian, 19 Cladocera and 16 Copepoda were recorded, which belong to 9 family and 19 genera.
The biodiversity index revealed significant seasonal variation of the crustacean diversity. The dominant Cladocera species in spring, summer and autumn-winter were Moina micrura, Bosmina longirostris, Diaphanosoma leuch, respectively. Cyclopidae strenuus was the dominant Copepoda species in winter-spring while Eucyclopinae macruroides and Thermocyclops tsihokurnsisin summer-autumn. Similarly, species diversity remained high in spring and autumn, but decreased in summer and winter. The highest dividual density was in spring, and the lowest was in winter. According to integrated biological diversity index, water quality of Baiyangdian was mesotrophication. |
