城市低影响开发与水系联调系统治涝研究及应用

Research and Application of Urban Low Impact Development and Water System Joint Commissioning for Systematic Waterlogging Control

内涝频发成为城镇化过程中典型的“城市病”,城市内涝需要从源头、管渠到河湖水系进行系统化治理。基于模型量化分析,提出低影响开发和闸门、泵站等对城市内涝的控制措施及其优化方法,通过内涝面积、积水深度、积水时间、溢流量等参数,评价不同组合措施下的内涝程度,并以长江流域典型城市的真实降雨情景,评价低影响开发与水系联调不同方案下的治涝效果。

Frequent waterlogging has become a typical“urban disease”in the process of urbanization.Systematic treatment from the source,pipe canal to river and lake water system is necessary to solve urban waterlogging.The effect of low impact development,gates and pump stations on urban waterlogging control and the optimization methods were proposed based on the quantitative analysis of the model.The waterlogging degree under different measure combinations was evaluated from the waterlogging area,waterlogging depth,waterlogging time,overflow and other parameters.The waterlogging control effect under different schemes of low impact development and water system was also evaluated by joint commissioning based on the real rainfall scenario of typical cities in the Yangtze River basin.
