摘要
雨水收集与利用是我国"海绵城市"建设的重要环节。本文以武汉园博园为研究对象,结合实地调研,从水资源总体规划、雨水系统和具体LID技术进行深入分析。结果显示,园中的雨水系统分为收集、弃流、处理和利用四个系统,借助屋顶绿化、雨水花园、透水路面等LID技术,实现雨水系统的高效运行,并有效地解决场地雨水收集、净化、储存与再利用问题。最后对雨水收集利用技术在其他城市公园绿地甚至更大尺度的绿地系统推广的必要性与可能性进行了探讨。
Rainwater collection and utilization is an important link in the construction of'sponge city"in China.Taking Wuhan Garden Expo as the research object and combined with field research,this paper makes in-depth analysis on the overall planning of water resources,rainwater system and specific LID techniques.The results show that the rainwater systems are divided into four systems that are collection,discard,treatment and utilization.With the help of LID techniques,such as roof rainwater collection,green space rainwater retention and square or road rainwater seepage,the rainwater system can be efficiently operated,which can effectively solve the problem of rainwater collection,purification,storage and reuse.Finally,the paper discusses the necessity and possibility of the promotion of rainwater collection and utilization techniques in other urban gardens and green space systems.
