| 摘 要： | 2006年初对广东省大镜山水库实施了生态修复工程,工程运行一年后,对该生态修复工程的效果进行了分析,结果表明：生态修复技术实施一年后,大镜山水库富营养化水平明显降低。与进水口（C区）相比,生态修复工程区（A、B区）透明度增加,氮、磷营养盐含量都有不同程度的降低。生态修复工程区TN、NH4-N与C区同期比最大降幅分别达19.6%、90.4%,TP、PO4-P同期比最大降幅分别达49.5%、67.5%,同时生态修复工程区内的叶绿素浓度也明显低于C区。

| Abstract: | An ecological restoration engineering was conducted for eutrophication control in the Dajingshan Reservoir of Zhuhai city in Guangdong province.After ecological engineering,the water quality turned better.The water Secchi depth increased 50%;TN and NH4-N concentration in reservoir water decreased 19.6%and90.4% respectively;TP,chlorophyll concentration and nutrition state index reduced too. The results indicated that ecological restoration engineering is an ideal method to control the eutrophication of reservoir. |
