城市雨水径流生态处理研究现状与进展

从城市雨水径流产生的问题出发，分析对城市雨水径流进行生态处理的必要性。对包括植被缓冲带、植被浅沟、生物滞留系统、滞留塘和人工湿地等在内的多项雨水径流管理与利用生态技术的优缺点、净化机理、适用条件等进行了综合比较。并对我国城市雨水径流生态处理技术的应用前景进行了展望，为生态城市建设和城市水环境改善提供借鉴。

Ecological Treatment of Urban Storm Water Runoff: Treatment and Progress

Urban development rapidly these years and it caused the amount of stormwater runoff increasing, surface runoff pollution and groundwater depletion. So it was necessary to treat storm water runoff by ecological ways. In this paper, we made a comprehensive comparative study of the advantages- , disadvantages, purification mechanism and the applied conditions of different ecological techniques- ,-including grassed filtering belt, grassed swale, bio-retention system, rainstorm pond, rainstorm wetland and so on. At the end of the paper, we gave prospects of urban runoff ecological treatment application in China. The results would be useful for eco-city construction and water environment improvement.
