摘要
针对水生态安全评价这一问题,采用“压力-状态-响应”(PSR)模型,运用熵权法来确定权重和水生态安全的综合评价值,并分析评价2012年~2021年襄阳市水生态安全水平,结果表明:2012年~2021年襄阳市水生态安全水平处于上升趋势,水生态安全水平总体上经历了由中警状态向预警状态的转变,在降水较丰富的年份表现为较安全或安全,但在平水年和枯水年还是存在不安全的风险。为保障襄阳市的水生态安全,未来襄阳市需进一步增强节水意识,提高水资源利用效率。
Aiming at the problem of water ecological security evaluation,the'Pressure-State-Response'(PSR)model is adopted,and the entropy weight method is used to determine the weight and the comprehensive evaluation value of water ecological security,and the water ecological security level of Xiangyang City from 2012 to 2021 is analyzed and evaluated.The results show that the water ecological security level of Xiangyang City is on the rise from 2012 to 2021,and the water ecological security level has generally undergone a transition from a medium warning state to an early warning state.It is safer or safer in years with abundant precipitation,but there is still an unsafe risk in normal and dry years.In order to ensure the water ecological security of Xiangyang City,it is necessary to further enhance the awareness of water conservation and improve the utilization efficiency of water resources in the future.
