基于层次分析的安徽省水安全综合评价

Water Security Evaluation of Anhui Province Based on Analytic Hierarchy Process

区域水安全是保障区域可持续发展的基础。在考虑水资源特性和安徽省具体情况的基础上,构建了安徽省水安全综合评价指标体系,并采用层次分析法对安徽省2005年-2010年水安全状况进行了评价。结果表明,2005年-2010年安徽省水资源安全状况分别处于"不安全"和"基本安全"之间,水安全状况不容乐观。这一结论与集对分析法得出的结果有较好的一致性,表明基于层次分析的水安全评价方法可行、结论可靠。最后,从改善水安全状况的角度,在促进节约、提高水资源利用效率、改善水质等方面提出建议。

Regional water security is the basis of protection of the regional sustainable development. Based on the characteristics of water resources and specific situation of Anhui Province,a comprehensive evaluation index system of water security was de veloped, and AHP was used to evaluate the water security situation of Anhui Province from 2005 to 2010. The results suggested that the water security situation is between ＂unsafe＂ and ＂basically safe＂ in Anhui Province from 2005 to 2010 and thus water security situation is not optimistic. This conclusion was in coincidence with that determined by the set pair analysis, which indi- cated that AHP is feasible and reliable for water security evaluation. Finally, from the perspective of improving water security, some recommendations were proposed to promote savings, increase the utilization efficiency of water resources, and improve wa- ter quality.
