摘　　要：建设人工调蓄区暂存处理城市内涝废水可以缓解城市内涝压力,但随之形成浅水型人工湖泊,湖水与底泥中的污染物交换剧烈,比较容易发生水体富营养化,生态系统比较脆弱。广州市增城区新塘镇永和河调蓄区建设工程在整体施工中,通过改良及活化调蓄区底泥,构建沉水植物群落及水生动物群落和调蓄区水面,进而形成满足生态净水鸟类游禽水上栖息要求的复合型湿地。以该水利工程为例,探索了调蓄区草型湖泊生态系统的构建方法,分析了良性草型湖泊生态系统对水质的净化效果。The construction of artificial regulation and storage area for temporary treatment of urban waterlogging and wastewater can alleviate the pressure of urban waterlogging,resulting in shallow artificial lakes.The exchange of pollutants between lake water and sediment is intense,which is prone to water eutrophication and fragile ecosystem.Based on the Construction project in Yonghe River regulation and storage area,Xintang Town,Zengcheng District,Guangzhou,a compound wetland that meets the requirements of ecological water purification birds and swimming birds is formed by improving and activating the sediment in regulation and storage area,constructing submerged plant community,aquatic animal community and water surface.The construction method of macrophytic lake ecosystem in regulation and storage area is explored and the purification effect of benign macrophytic lake ecosystem on water quality is analyzed.
