针对频繁发生的暴雨内涝灾害给城市建设和管理带来的严峻挑战,以解决我国当前城市暴雨内涝问题为目标,从我国城市暴雨内涝灾害的发生现状入手,分析了城市暴雨内涝灾害的发生特点和主要诱因。以不同国家和地区城市暴雨内涝的成功案例为启示,结合我国城市暴雨内涝防治的新形势,总结并预测城市雨洪管理技术的发展趋势,提出了我国城市暴雨内涝问题应对的系统构想。该构想针对我国城市当前内涝问题给出以下3点建议:(1)采用先进的城市暴雨内涝治理技术,学习发达国家的经验;(2)充分利用雨洪模型,建立起一整套有效的城市暴雨洪水过程模拟模型;(3)构建一套适合我国城市的雨洪管理体系。通过以上3点实施,可推动我国城市化建设的深入开展,并对城市防汛减灾安全保障能力的提高及城市雨洪应对与应急管理水平的提升具有一定的参考价值。

For the severe challenges of urban construction and management brought by frequent rainstorms and waterlogging disasters,aiming to solve the problem of urban waterlogging in China at the present,we start from the current situation of urban rainstorm and waterlogging disasters,then analyze occurrence characteristics and main inducements of urban rainstorm and waterlogging disasters. Based on the successful cases of urban rainstorms in different countries and regions,and combining with the new situation of urban rainstorm and waterlogging prevention,we summarize and forecast the development trend of urban rain and flood management technology,and propose the system concept of coping urban waterloggingproblems. Through the proposal of this conception,we propose the following three suggestions for coping the current urban waterlogging in our country:(1) using advanced control technology of urban waterlogging which we can learn from the developed country;(2) we need to make full use of the rain-flood model to establish a set of effective urban storm-flood process simulation model;(3) we should build a set of rain and flood management system which is suitable for Chinese cities. The implementation of the above three points can promote the further urbanization construction in China,the implementation experiences will be some reference for improving the safety protection capabilities of urban flood prevention,disaster reduction,the improvement of urban rain and flood response and emergency management.
