基于DPSR模型的城市水安全评价与保障能力提升
Urban Water Security Assessment and Improvement Suggestions Based on Driver-Pressure-State-Response Model
摘要
Abstract
Assessing water security serves as the foundation for developing,utilizing,and protecting water re-sources.Enhancing urban water security promotes ecological environmental protection and supports high-quality eco-nomic 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 Chang-sha improved from unsafe level in 2018 to safe level in 2020,the state remains unstable.Consequently,three strat-egies are proposed to bolster water conservation efforts,improve water quality,and enhance disaster prevention ca-pabilities.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 conserva-tion,and then improving disaster prevention capabilities.关键词
