摘　　要：水安全评价是水资源开发利用与保护的基础,提升城市水安全有利于促进生态环境保护,支撑经济社会高质量发展。基于驱动-压力-状态-响应(DPSR)模型构建以资源安全、社会安全和经济安全为核心的水安全评价指标体系,运用熵权法确定指标权重,以长沙市为实例,对“十三五”期间城市水安全状况进行评估与分析。结果表明:长沙市水安全状况尽管从2018年“不安全”等级提升至2020年“安全”等级,但状态不稳定,进而制定了加强保水工程建设、提升水环境质量、加强水灾害防治能力3个方案,综合考虑方案投入成本并对比水安全提升效果,给出了先后实施方案2—方案1—方案3的长沙市水安全提升优化路径。Assessing water security serves as the foundation for developing,utilizing,and protecting water resources.Enhancing urban water security promotes ecological environmental protection and supports high-quality economic and social development.The DPSR(Driver-Pressure-State-Response)model was employed to construct a water security assessment index system centered on resource,social,and economic security.The entropy weight method was applied to determine index weights.The urban water security of Changsha City as a case study during the 13th Five-Year Plan period was evaluated and analyzed.Results indicate that while the water security of Changsha improved from unsafe level in 2018 to safe level in 2020,the state remains unstable.Consequently,three strategies are proposed to bolster water conservation efforts,improve water quality,and enhance disaster prevention capabilities.In consideration of the costs and effectiveness of these strategies,an optimized approach for enhancing water security in Changsha is recommended:prioritizing water environmental quality,followed by water conservation,and then improving disaster prevention capabilities.
