海绵城市指的是城市能够像海绵一样,在降水时,利用一些绿化植物的保水功能和蓄水池等收集雨水,实现放内涝及蓄水抗旱等功能。从而有效缓解城市水资源短缺与城市内涝之间的矛盾,并助力于修复城市水生态环境。构建海绵城市的经济效益不可小觑。海绵城市建设非常注重对天然水系的保护利用,相比于建设排水管道和钢筋混凝土水池的工程量,海绵城市建设在劳动力成本上又有了一大突破,调蓄设施往往与城市既有的绿地、园林、景观水体等相结合,“净增成本”减少。倘若海绵城市概念能够得以广泛实施,必然是现代社会的一大生态革命。
Sponge city refers to the city can sponge like, when precipitation, the use of some water conservancy plants and water reservoirs to collect rainwater, waterlogging and other functions such as water storage and drought. Thus effectively alleviating the contradiction between urban water shortage and urban waterlogging and helping to repair the urban aquatic environment. The economic benefits of building a sponge city can not be underestimated. Sponge city construction attaches great importance to the protection and utilization of natural water system, compared to the construction of drainage pipes and reinforced concrete pool volume, sponge city construction has a major breakthrough in labor costs, storage facilities are often associated with urban green space , Garden, landscape water body combination, “net increase cost ” reduce. If sponge city concept can be widely implemented, it must be a major ecological revolution in modern society.
