摘要
湖泊是城市生态系统重要组成部分,对城市的生态化建设具有特殊的意义。但近年来我国城市湖泊污染严重,水质堪忧。面对城市人工湖泊的水质恶化,水资源短缺等问题,我们对雨水、微污染湖泊进行了研究,结果表明雨水是一种可以利用的资源。文中介绍了雨水利用的重要性、城市雨水污染现状及城市雨水的处理与利用方法和人工湿地净化雨水补充湖水、改善湖水水质的系统设计及湿地植物选择与景观配置。
The lakes are an important component of urban ecosystems. They also have a special significance to ecological construction of cities. But in recent years, Chirka＇S urban lakes have been seriously polluted which made the water quality be anxious. To face the prob- lems of urban man- made lake＇s water quality deterioration, water shortages and etc, some research of rain and micro- polluted lakes are done. The results show that rain is a resource that can be used. This paper introduces the importance of rainwater utilization, the situation of polluted urban rainwater and its processing and utilizing methods. The additional information contains constructed wetlands which can purify rainwater, the system design to improve lakes water quality, and the selection and landscape configuration of wetland plant.
