基于水文过程的城市湖泊雨水利用系统的构建方法研究——以武汉梦泽湖为例

Study on the Construction Method of Urban Lake Rainwater Utilization System Based on Hydrological Process——Take Mengze Lake in Wuhan as an Example

城市开发使天然湖泊的供水源大量受阻,导致湖泊在数量与面积上的大幅减少。而湖泊的减少,又加剧了城市内涝的发生。为了改变这种状况,众多城市开始营建人工湖,而兴建的城市人工湖又需要大量的市政补水来填充,实际上城市内涝也未得到有效缓解。本文在研究城市水文过程的基础上,以武汉市梦泽湖的应用研究为例,提出湖泊雨水利用系统的构建方法,予以最大效率地利用雨水来补充城市人工湖水源,同时减少城市内涝的发生。

Urban development has intensely hindered the water supply of natural lakes,leading to a signi cant reduction in the number and area of lakes.The decreaseareao akes has intensi ed the occurrence of urban waterlogging.For this situation,many cities have begun to construct arti cial lakes,while the urban arti cial lakes need a lot of municipal supplementary water to ll them.With such a situation,the urban waterlogging has not effectively alleviated.Based on the study of the urban hydrological process,this paper takes the application research of Mengze Lake in Wuhan as an example.It proposes the construction method of lake rainwater utilization system to maximize the use of rainwater to supplement the public arti cial lake water source while reducing the occurrence of urban ooding.
