“海绵城市”理念下的下沉式绿地空间设计研究

Study on Sunken Green Space Design under the Concept of “Sponge City”

以"海绵城市"为理念,结合美、德、澳、日、英、新西兰等发达国家及国内对雨水资源的利用研究来阐述构建下沉式绿地空间设计,建设可持续性、弹性的绿色城市,要从源头管理雨水,满足、完善城市给排水等功能,注重城市生态环境的保护和修复。文章以绿地公园、广场绿地、立交桥绿地、城市道路、居住区绿地等空间设计为载体,来提高控制雨水径流的渗透、调蓄、净化利用和排放能力,维持或恢复城市的"海绵弹性"功能,实现城市良性水文循环。

Based on the concept of＂Sponge City＂,and combining with the studies on the application of rainwater resource in developed countries like the United States,Germany,Australia,Japan,Britain and New Zealand as well as in China,this thesis elaborates that to build sunken green space design and construct sustainable and flexible green city require the management of rainwater from the source,the improvement of urban water supply and drainage functions and the emphasis on the protection and restoration of urban ecological environment. The thesis takes the space design such as green parks,square greenbelt,overpass greenbelt,urban roads and residential greenbelt as the carrier,so as to improve and control the infiltration,regulation and storage,purification use and emission capacities of rainwater runoff,to maintain or restore the city’s＂elastic sponge＂function and to achieve a benign urban hydrologic cycle.
