摘要:
当前全球气候变化导致洪涝灾害频繁发生,尤其一些高强度、极端性的城市降水洪涝事件更是严重损害了人民群众的生命财产安全。郑州“7·20”特大暴雨内涝灾害是新中国成立以来最严重的城市内涝灾害,国内外专家学者对暴雨的特性及成因、内涝形成机理与防治途径等开展了大量研究。在此,本文系统回顾郑州“7·20”特大暴雨城市内涝灾害,梳理了近年来城市内涝及郑州“7·20”特大暴雨内涝灾害的相关研究和主要成果,解析了郑州“7·20”特大暴雨的重现期、时空分布、形成机理等特性;分析了内涝形成机理与防治途径,以及城市排水防涝基础设施、洪涝应急指挥、风险管理和城市规划中存在的主要问题。综述结果表明,此次郑州暴雨具有极端性和难预测性的特点,其中单日和累积降水均超过历史极值。由于台风、地形以及“雨岛效应”的耦合综合影响造成了此次强降水天气过程。“7·20”特大暴雨城市内涝灾害暴露出郑州城区排水防涝基础设施、建设存在明显短板;河道防御体系存在瓶颈卡口;以及应急设施和管理能力不足等问题。基于上述问题,应适当调整内涝防治标准,增强洪涝风险管理与规划建设管控措施,建设外洪内涝同防控的工程体系,加强城市洪涝智慧调度与应急指挥决策等方面的能力。
Abstract:
Recently, the global climate has sharply changed, which led to frequent floods. The specific high-intensity and extreme rainfall, and the consequent flood events occurred in the urban areas have seriously damaged the safety and property of residents.There was a torrential rainfall event happened in Zhengzhou on July 20th, 2021,which caused the most serious urban pluvial flood disaster since 1949 in China. Many studies have been done to explore the cause and mechanism of formation as well as the characteristics of the serious rainstorm,in order to improve the urban flood prevention and control. This paper analyzed the relevant studies of urban waterlogging systematically, especially focused on the Zhengzhou “7·20” Torrential Rain waterlogging disaster. Three contents were discussed, including: 1) the return period, spatial-temporal distribution and formation mechanism of the storm event 2) the shortcomings of drainage and waterlogging prevention infrastructure, as well as the weakest li<x>nk effect of emergency facilities 3) the main problems existing in urban flood emergency management 4) risk management and urban planning considering flood situation. The results show that the rainstorm in Zhengzhou has the characteristics of extreme and difficult to predict, and the single-day and cumulative precipitation both exceed the historical extreme values. Due to the coupling and comprehensive influence of typhoon, topography and "rain island effect", the heavy precipitation weather process was caused. Zhengzhou "7·20" pluvial disaster exposed the obvious shortcomings of drainage and waterlogging prevention infrastructure and construction in Zhengzhou city. There are bottlenecks in the river defense system. And inadequate emergency facilities and management capacity. ba<x>sed on the above problems, it is necessary to appropriately adjust the waterlogging prevention and control standards, strengthen the flood risk management and planning and construction control measures, build the engineering system of external flood waterlogging and prevention and control, and strengthen the intelligent dispatching and emergency command and decision-making ability of urban flood.
