基于层次分析法的陕西省水资源安全评价

Water Security Evaluation of Shaanxi Province Based on Aanalytic Hierarchy Process

针对陕西省水资源状况,利用层次分析法从经济、社会、供需和生态安全四个方面建立评价指标体系,并通过分析各个指标的权重进行层次总排序,对陕西省10个城市的水资源安全状况进行综合评价,结果表明:汉中市的水资源安全等级最高,安康、西安、渭南、商洛、宝鸡、榆林、咸阳次之,延安和铜川市的等级最低,评价结果基本符合陕西省实际情况.如此严峻的水资源短缺问题必将在陕西省未来水资源可持续发展过程中引起相关部门的高度重视.
