| 中文摘要: |
| 在全球气候变暖与快速城镇化的背景下,极端暴雨洪涝发生的可能性与不确定性在增大,同时洪涝威胁对象、致灾机理、成灾模式、损失构成与风险特性均在发生显著变化。本文基于郑州"7.20"特大暴雨水灾的实地调研与典型案例的剖析,阐述当代社会洪涝风险连锁性、突变性、传递性的演变机理与趋向,结合国际社会与水共存、韧性提升的理念与实践,探讨变化环境下与新时代基本国情相适宜的洪涝灾害防治策略。研究结果表明,应对快速城镇化进程中极端暴雨洪涝灾害,需以流域为单元做好综合治水的统筹规划;韧性城市只有建成不怕淹的城市,才有利于实现人水和谐的目标;在发展不均衡、不充分的现实条件下,完善与健全洪涝灾害风险管理与应急管理体制与运作机制,不仅在于保障安全,而且要为新时代经济社会快速平稳发展保驾护航。 |

| In the context of global climate warming and rapid urbanization,the possibility and uncertainty of extreme rainstorm flooding are increasing,while the objects threaten by floods,disaster-causing mechanism,disaster mode,loss composition and risk characteristics are changing significantly.Based on the field investigation and analysis of typical cases of the"7.20"extreme rainstorm flood disaster in Zhengzhou in July 2021,this paper expounds the evolution mechanism and trend of the linkage,mutation and transmissibility of flood risk in current society,and combined with the concept and practice of international community coexisting with water and enhancing resilience,the flood disaster prevention and control strategy suitable for the basic national conditions of the new era under the changing environment is discussed.The results show that to deal with extreme rainstorm and flood disasters in the process of rapid urbanization,it is necessary to make overall planning of comprehensive water control based on watershed.Only by building a city that is not afraid of flooding can we achieve the goal of harmony between man and water.In the reality of unbalanced and inadequate development,the improvement and perfection of flood disaster risk management and emergency management system and operation mechanism is not only to ensure safety,but also to escort the rapid and stable economic and social development in the new era. |
