| 中文摘要: |
| ２００５～２００７年在长江上游通天河至重庆江段干支流设６０个采样站，２００３～２００７年在重庆以下至三峡水库坝前水域设３３个采样断面进行轮虫调查，结果在长江上游（通天河至重庆）江段共采集到１３８种（含亚种）轮虫，隶属于２纲、３目、２２科、４０属；重庆以下至三峡水库坝前共采集到１６７种轮虫，隶属于２纲、３目、２３科、４７属；三峡水库蓄水后的第１年、第２年，重庆以下至三峡水库坝前水域轮虫种类数迅速增长，到蓄水后的第３年开始下降。通过不同区域轮虫群落相似性比较，水电开发强度较大的金沙江下游与三峡库区轮虫群落相似性明显高于金沙江上中游江段，表明水电开发对金沙江下游、长江上游宜宾至重庆段轮虫群落产生了较为明显的影响。

| 英文摘要: |
| Rotifers were sampled along the upper reaches of the Yangtze River, with 60 sampling sites on main stream from the source （Tongtian River） to Chongqing in 2005 -2007, and 33 sites in the Three Gorges Reservoir （from Chongqing to the Dam） in 2003 - 2007. There were I38 species of rotifers （including subspecies） collected in the upper reaches （from Tongtian River to Chongqing） , belonging to 2 classes 3 orders 22 families and 40 genera while 167 species were collected in the reaches from Chongqing to the Dam, belonging to 2 classes 3 orders 23 families and 47 genera. The number of rotifer species increased rapidly in TGR during the first and second year after the impoundment, but decreased from the third year. The analysis of Percentage Similarity of Community （PSC） between different reaches shows that the rotifer communities have been affected by the hydropower development in the lower reaches of Jinsha River and the upper reaches of Yangtze River from Yibin to Chongqing. |
