摘要
城市暴雨洪涝灾害是目前我国城市最突出的水患灾害。2023年9月7日,深圳市发生极端特大暴雨,深圳河流域处于暴雨中心,造成较严重洪涝灾害,本次暴雨洪涝灾害为流域水安全保障敲响了警钟。通过全面总结深圳河流域暴雨洪涝特性及防御情况,分析暴雨洪涝灾害成因,在此基础上,从提高河道泄洪能力、增大流域洪水调蓄能力、加强城市排水防涝能力建设、强化超标准暴雨应急管理能力等方面提出洪涝治理对策,思考城市洪涝治理方式和理念,为系统解决洪涝问题、提升高密度城市洪涝防御能力提供参考。
Urban rainstorms and waterlogging disasters are the most prominent disasters in cities.An extremely heavy rainstorm occurred in Shenzhen on Sep.7,2023.The Shenzhen River Watershed locates at the center of the rainstorm,and suffers significant flood disaster.The rainstorm flood disaster sounded the alarm for the water security of the city.Based on the summary of characteristics and prevention of rainstorm and flood in the Shenzhen River Watershed,the causes of rainstorm and flood disasters are analyzed.Furthermore,strategies are proposed from the aspects of improving the flood discharge capacity of river channels,increasing the flood storage capacity of the watershed,strengthening the construction of urban drainage and flood prevention capacity,and improving the emergency management capacity of the rainstorms beyond designed standard.Then,thinkings on the urban flood control methods and concepts are presented.It provides a reference for solving the flood problem and improving the flood prevention capability of high-density cities.
