变化环境下城市安全设防与防洪韧性提升思路探析OA
Analysis of urban safety fortification and flood resilience enhancement under changing environments
城市防洪安全事关人民生命财产安全和经济社会高质量发展大局,我国历来重视城市防洪安全工作.2022年水利部启动七大流域防洪规划修编,系统梳理流域重要防洪城市防洪达标情况,全面分析防洪形势与需求,科学论证确定城市防洪标准,为布局城市防洪工程、实施城市防洪治理奠定了坚实基础.当前,全球气候变化影响加剧,叠加快速城镇化影响,我国城市洪涝灾害风险攀升、灾害链生级联效应凸显,安全韧性城市建设面临新形势新挑战.从法律、技术、规划三个方面梳理我国城市防洪设防依据,分析城市防洪达标现状,总结两轮流域防洪规划中城市防洪标准变化情况,本着"跳出防洪看防洪"的原则,结合实际案例,阐释城市安全设防在技术标准协调性、安全裕度量化、差异化设防等方面存在的问题和面临的挑战,并从加强技术标准协调、完善洪涝灾害防御体系、加强基础研究、强化规划统筹等方面,阐述认识并提出建议,以期为推动我国城市安全设防技术标准体系优化与安全韧性城市建设提供参考借鉴.
Urban flood control safety bears on people's lives and property as well as the overall advancement of high-quality economic and social development.China has always attached great importance to urban flood control safety.The Ministry of Water Resources started the revision of flood control planning for seven major river basins in 2022.It systematically reviewed the flood control compliance status of key flood control cities in the river basins,scientifically demonstrated and determined the urban flood control standards,and comprehensively analyzed the flood control situations and demands,thus laying a solid foundation for the deployment of urban flood control projects and the implementation of urban flood control systems.Currently,driven by the intensifying influence of global climate change and rapid urbanization,the risk of urban flood disasters in China is rising and cascading effects of disaster chains are prominent,which poses new situations and challenges to the construction of safe and resilient cities.From the three perspectives of law,technology,and planning,this paper sorted out the basis for China's urban flood control fortification,analyzed the current status of urban flood control compliance,and summarized the changes in urban flood control standards in two rounds of river basin flood control planning.By following the principle of"viewing flood control from a broader perspective"and combining practical cases,this paper elaborated on the issues and challenges of urban flood control fortification in terms of technical standard coordination,safety margin quantification,and differentiated fortification.Additionally,it put forward relevant insights and proposals from the perspectives of strengthening the coordination of technical standards,improving the flood disaster defense system,enhancing basic research,and strengthening integrated planning and coordination.This paper aims to provide reference for promoting the optimization of China's technical standard system for urban flood control fortification and the construction of safe and resilient cities.
