2012年,海绵城市这个概念首次被提出,就引起了不小的反响。海绵城市(LID)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,实现防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。本文从快速路建设角度出发,对海绵城市展开研究分析,以供同行参考。 In 2012, sponge city concept was first proposed, it caused no small reaction. City sponge (LID) refers to the city can sponge, like, in the precipitation, the use of some of the plants of the water retention function and the reservoir to collect rainwater, waterlogging and waterlogging and other functions. 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. This article from the perspective of expressway construction, sponge city to start a research and analysis, for peer reference.
