基于城市生态化雨洪管理的径流污染控制措施优化方法研究

Study on the Optimization Methods of Runoff Pollution Control Measures Based on Urban Ecological Stormwater Management

在我国,快速的城镇化进程使得城市硬质化比率激增,雨水径流所造成的面源污染治理正受到越来越多的关注。"海绵城市"建设通过对低影响开发雨洪管理措施的推广,给城市面源污染治理带来了机遇。本文在分析、比较不同雨洪管理净化措施的净化机理后,对相关措施的构造做法提出以提高雨水净化效率为目标的优化方案,并对城市生态化雨洪管理面源污染控制措施的景观营造手法予以阐述,以期兼顾城市面源污染控制、提升城市环境品质、提供休闲游憩机会等多重功能,为海绵城市建设发挥引导性作用。

In China, rapid urbanization has led to a sharp increase in urban hard pavement, and the nonpoint source pollution caused by stormwater runoff is receiving more and more attention. The construction of ＂sponge city＂ has brought opportunities for cities＇ non-point source pollution control through the promotion of stormwater management measures for low impact development. Based on the analysis and comparison of different purification mechanisms of purification measures for stormwater management, this paper proposes the optimization solution to the construction practices of relevant measures with the aim of improving the efficiency of stormwater purification, and also elaborates the landscaping techniques for the non-point pollution control measures of urban ecological stormwater management, in an attempt to realize the multiple functions： keeping urban non-point source pollution under control, improving urban environment quality and providing amenities for leisure and recreation so as to play a leading role in the construction of spongy cities.
