摘要
通过修建拦河闸(坝)形成城市河道人工水面,是一项蓄泄兼顾的水利工程,具有美化环境、防洪、调节区域小气候及休闲娱乐的生态服务、社会、经济多种功能.以渭河宝鸡市区段防洪及生态治理工程为例,分析了城市河道人工水面水质污染的原因和变化规律,指出其污染类别主要包括降雨形成的地表径流、大气沉降、合流制管道溢流及底泥二次污染等,在此基础上提出相应的污染防治措施,旨在对城市人工水面的建设及运行管理提供一定的参考价值.
It is a significant hydraulic project to build a dam to form a man-made lake in a river. The many advantages include：flood control, local weather modification, entertainment,and environmental purification. A case of ecological engineering of Weihe River which runs through the city of Baoji was investigated. The results showed that water pollution in the man-made lake was caused by the storm runoff, combined with sewer overflows, air pollution, river sediment, etc. Then some engineering measures to control water pollution were recommended. The result would give some reference for project management of water quality in the man-made lake.
