雨水花园在长江大保护岳阳项目中的应用

Application of Rainwater Garden in Yueyang Project for the Yangtze River Protection

以长江大保护岳阳项目某小区海绵改造工程为研究对象,设计过程中结合小区实际绿化用地,采用雨水花园、下沉式绿地等设计理念的海绵改造方法,得出应结合地理环境,明确海绵改造功能,才能确保雨水在雨水花园中滞留、下渗与吸收,防止小区内涝的结论,最终实现雨水的再生循环利用。

Taking the project of sponge reconstruction in a residential area concerning Yueyang Project for Protecting Yangtze River as the research object,the process of design combines the actual green land in the area with the methods of sponge reconstruction differing from the design of rain garden and subsided green land. It is concluded that geographical environment should be combined with and the function of sponge reconstruction should be clarified,so that rainwater can be held together,infiltrated and absorbed in the rainwater garden. In so doing,the residential area is not liable to be waterlogged. Eventually,rainwater can be recycled.
