摘　　要：近年来,我国极端暴雨事件频发,造成城市洪水和内涝的同时,也给应急处置、抢险救灾带来极大的挑战,社会经济和人民财产安全都受到了严重损失。从全球气候变暖、城市化等方面分析极端暴雨产生的原因,同时阐述了目前城市防洪排涝系统建设落后、洪涝治理矛盾日益加剧、防洪排涝设施标准不足、防洪排涝设施重建轻管等问题,并提出了要应对极端暴雨事件,城市防洪排涝系统建设必须做好培育城市防洪排涝系统韧性、做好防洪与排涝的标准衔接、补齐城市洪涝防治工程短板、提升城市排水设施运维水平等4个方面的工作,可以为极端暴雨事件下的城市防洪排涝系统建设提供参考。In recent years,China has faced a surge in extreme rainfall events,leading to urban flooding and inundation.This has presented formidable challenges to emergency response and disaster relief efforts,resulting in substantial losses both in socioeconomic terms and people's property.This paper delves into the causes of these extreme rainfall events,considering the perspectives of global warming and urbanization.Concurrently,it sheds light on prevailing issues within the urban flood and inundation prevention system,including construction setbacks,mounting contradictions,insufficient facility standards,and a disparity between construction and management.To effectively address extreme rainfall events,it is crucial to bolster the resilience of urban drainage systems,establish robust standards for flood control and drainage,rectify deficiencies in urban flood and inundation control projects,and enhance the operational efficiency of urban drainage facilities.The objective of this paper is to furnish a theoretical foundation for the development of urban flood and drainage systems in response to extreme rainfall events.
