基于海绵城市建设的雨水花园技术综述

A Review on Technologies of Rain Garden Based on the Construction of a Sponge City

雨水花园是1种适用范围广、造价成本低、形式多样化的绿色基础设施。目前在实验研究以及工程应用中,雨水花园对雨水径流的处理展现出显著的成效,对海绵城市的建设具有重要意义。介绍了雨水花园的结构,阐述了常规式、串联式和下凹式雨水花园等基本布置形式及建造过程位置选择、面积计算和植物选择等技术,综述了其功能与研究状况,展望了雨水花园的应用前景。

Rain garden is a green infrastructure with the characteristics of wide application scope, low construction cost and diversified forms. At present, it is effective in the treatment of rainwater runoff both at experimental and practical levels so as to have great significance to the construction of a sponge city. Firstly, the structure of rain garden was introduced, and then three basic layout types namely conventional, cascade and concave rain gardens were presented. In respect to technologies of the construction, site location selecting, area computing and vegetation choosing were discussed. Besides, the function and research progress were summarised, and the future application of rain garden has been prospected.
