摘　　要：2009年4月～2009年12月对滇池海东湾地区12个点位的轮虫群落结构进行了调查研究,共鉴定7科11属23种轮虫,龟甲轮虫属的数量最多,臂尾轮虫属的种类最多;轮虫密度:夏季>秋季>冬季;离湖岸越远轮虫数量越少。This study researched of rotifer community structure of 12 sites in Dianchi Lake from Apr. 2009 to Dec. 2009. 23 species, 11 categories and 7 families of rotifers were identified. The abundance of the Keratella was the highest and species number of the Branchionus was the highest. The average density of rotifer was the peak in summer, the second highest in autumn and the lowest in winter. The sites near the lakeshore had more rotifers than farther.
