基于滨水绿地的雨水分质处理与景观设计方法

目前,建筑与小区的海绵城市系统设计一般通过有组织的汇流进入源头低影响开发设施进行下渗、净化。但相对干净的屋面雨水和污染较重的路面雨水采用相同的技术措施会造成低影响开发设施的浪费。而滨水绿地并没有服务于周边小区的雨水径流处理,造成一定的资源浪费。探索一种基于滨水绿地的雨水分质处理系统,以嘉兴市某新建小区项目(柳岸禾风)为例,论证雨水分质处理措施对雨水径流控制的作用,并探索相对应的景观设计方法,最终实现滨水绿地的景观效益和生态效益,体现蓝绿交融的理念。

Rainwater quality treatment and landscape design methods based on waterfront space

At present,the sponge city system design of buildings and communities generally enters the source low-impact development facilities for infiltration and purification through organized confluence.This method has certain disadvantages including relatively clean roof rain and heavily polluted road rain use the same technical measures,resulting in waste of low-impact development facilities.The waterfront green space does not serve the rainwater runoff treatment of the surrounding communities,causing a certain waste of resources.This paper explores a rainwater quality treatment system based on waterfront green space.Taking a newly built community project in Jiaxing(Liuanhefeng)as an example,this paper demonstrates the effect of rainwater quality treatment measures on rainwater runoff control,and explores corresponding landscape design techniques.Finally realize the landscape and ecological benefits of the waterfront green space,reflecting the idea of blending blue and green.
