海绵城市设施建设效果监测体系构建与应用

Establishment and Application of the Monitoring and Assessment System of Sponge City Facilities Construction

海绵城市作为缓解城市内涝、控制城市水污染的重要策略之一,在我国受到广泛关注。海绵城市建设过程中的效果监测及评估是不可缺少的组成部分,可为海绵绩效考核提供量化指标,为海绵设施的运行维护提供基础数据。结合工程规划及海绵城市“源头-过程-末端”的污染控制技术体系,提出基于“本底-源头-过程-末端”的水量水质效果评估监测体系。在此基础上,以某海绵试点城市为例,对监测体系的构建及实施进行验证。结果表明,海绵设施能有效缓解城市内涝,对面源污染削减效果较好,有利于流域水环境的改善。该监测体系可为海绵城市建成区域运维阶段的水量水质管理提供监测依据和数据参考。

As one of the vital strategies for mitigating urban waterlogging and controlling urban water pollution,sponge city has garnered widespread attention in China.Concurrently,within the process of constructing sponge cities,monitoring and evaluating the effectiveness is an indispensable component.This evaluation can yield quantitative indicators for assessing sponge performance and provide fundamental data for the operation and maintenance of sponge facilities.Therefore,by integrating the engineering planning and the pollution control technology system of“source-midway-end”approach in sponge city development,this article proposes a water quantity and quality evaluation and monitoring system based on the“background-source-midway-end”framework.Based on above,on site monitoring in a sponge pilot city was used as a case study to demonstrate the applicability of the proposed framework.The results indicated that sponge facilities can effectively alleviate urban waterlogging,reduce non-point source pollution,and improve the water environment in the watershed.Furthermore,the monitoring system can offer a foundation for monitoring and serve as a data reference for water quantity and quality management during the operation and maintenance phase of the sponge city built-up area.
