高密度城市暴雨洪涝防御对策——郑州“7·20”特大暴雨启示

Countermeasures for rainstorm and flood prevention in high-density cities——the“7·20”heavy rain revelation in Zhengzhou

城市暴雨洪涝灾害是目前我国城市最突出的水患灾害。结合郑州“7·20”暴雨启示,通过深入分析我国高密度城市暴雨洪涝主要特征、成因,从“防御体系有韧性、基础设施有韧性、极端暴雨少损失”三个方面,提出高密度城市暴雨洪涝防治对策,为系统解决我国城市洪涝问题、提升城市洪涝防御能力和韧性提供新思路。

Urban rainstorm flood disaster is the most prominent urban flood disaster in China.Combined with the"7·20"heavy rain revelation in Zhengzhou,through in-depth analysis of the main characteristics and causes of heavy rainfall and flood in high-density cities in China,from the three aspects of"resilience of defense system,resilience of infrastructure,and less loss in extreme rainstorm",the countermeasures of rainstorm flood prevention and control in high-density cities are proposed.It provides a new idea for solving urban flood problems systematically and improving urban flood defense and resilience.
