摘　　要：大宁河是三峡库区一条重要的支流,是著名的小三峡旅游胜地,2003年6月三峡水库蓄水后,大宁河水质出现了异常现象。2003年9月课题组对三峡135m蓄水后的大宁河回水段进行了富营养化监测。通过监测结果评价,发现大宁河双龙银窝滩段水体处于中营养中富营养状态。针对这种情况分析了水质变化原因,提出了5项防治对策。Daninghe River is a very important tributary in the area of Three Gorges reservoir. It is also a famous scenic spot. An abnormal phenomena appeared after the storage of the reservoir in June 2003. In September 2003, eutrophication monitoring in the 135m backwater reach of Daninghe River was conducted and the data were simply analyzed. The assessment conclusion is that reach backwater from Shuanglong to Longmen Gorge is in a mesotrophic or eutrophic condition. At the same time, the causes and countermeasures of its nutrition change has been discussed.
