摘要

随着城市化进程加快,极端暴雨引发的城市内涝问题不断加剧,海绵城市与低影响开发理念逐渐在现代城市建设中得以实践。但目前在城市降雨径流、水体污染物运移及其与低影响开发模块间相互作用机制研究还有所欠缺。通过归纳国内外相关文献,分析目前常用雨洪模型特征、功能与局限,探讨了径流污染运移过程与低影响模块中植被、土壤、水力条件等作用机制。未来关于城市雨洪、径流污染控制以及低影响开发建设,应提高空间数据处理能力,提升系统可靠性、风险性分析和经济分析能力,根据研究案例的特殊要求耦合模型并照顾到径流污染物运移与低影响开发模块的相互作用机制,以构建城市雨洪管理与城市可持续发展体系。
        With the acceleration of urbanization process, water logging problems are exacerbating by extreme rainstorms in urban areas. The concepts of "Sponge City" and "low impact development(LID)" have been gradually practiced in modern urban construction, however, there is still lack of research on the interaction mechanism between urban rainfall runoff, water pollutant transport and LID modules. In this paper, the related literatures were summarized, the characteristics, functions and limitations of current popular rain-flood models were analyzed, and the interaction mechanisms between LID modules and vegetation, soil and hydraulic conditions during pollutant transport were investigated. The future challenge lies within the spatial data processing ability, system reliability improvement, risk analysis and economic analysis ability. The model coupling considers the interaction mechanism between runoff pollutant migration and LID modules based on case studies, which forms sustainable urban development system and rainfall-flood management.
