摘要
指出了城市化的快速发展增加了城市内涝风险和雨水径流污染。建设海绵城市要求加大城市径流雨水源头减排的刚性约束,削减城市径流污染负荷,充分发挥从源头对雨水的吸纳、蓄渗和缓释作用。雨水花园和绿色屋顶作为海绵城市建设中常用的LID措施,在减少径流量和改善径流水质方面发挥着重要作用。介绍了雨水花园和绿色屋顶的组成结构,并对雨水花园和绿色屋顶截流减污效率进行了分析,为城市化过程中的居民小区和广场建设优选工程措施提供参考。
With the rapid development of urbanization,the increasing impervious area has increased the risk of urban waterlogging and runoff pollution.The construction of sponge city is required to strengthen the rigid constraint of emission of urban runoff rainwater,reduce pollution load of urban runoff.Rainwater garden and green roof that are commonly used as LID measures,which plays an important role in reducing runoff and improving runoff water quality in the constructionof sponge cities.In this paper,the structures of rain garden and green roof were introduced,and the runoff interception and pollution reduction effects of them were analyzed in order to provide theoretical reference of the engineering construction optimization measures in residential areas and squares.
