摘要:

以工程保障、社会经济保障、环境保障和效率保障作为南通市沿海开发水资源保障能力评价的准则层,以缺水率、有效灌溉面积率、单位GDP用水等12个指标作为指标层构建了南通市沿海开发水资源保障能力综合评价指标体系。采用层次分析法和专家评分法确定指标权重,通过加权平均确定综合评价值。评价结果为:南通市现状综合保障能力中等,未来在充分节水、保护环境、提高用水效率的前提下,水资源保障能力将有所提高。从分类保障情况看,全市工程保障能力最好而环境保障能力最差;从各行政区的保障能力看,如皋市综合保障能力最好,而海安和如东两县综合保障能力最差。最后对如何提高各地区水资源综合保障能力作了讨论

Abstract:

Taking project guarantee,social economy guarantee,environmental guarantee and efficiency guarantee as criterion layer,12 indicators including water deficient ratio,effective irrigated area ratio and water consumption per unit GDP etc.as indicator layer,the evaluating indicators of waterresource guarantee for Nantong City is constructed.The Analytic Hierarchy Process (AHP) and expert grading method are used to determine the weight of each indicator,and weight average methodology is used to get the evaluation result.Results demonstrate that Nantong City owns a medium waterresource support capability now and will improve to some extent in the future on the basis of saving water,protecting environment and increasing wateruse efficiency.From the results of every criterion layer,the engineering project owns the best capability,while the environment owns the worst capability for the development of Nantong City.From the result of every district,the integrated support capability of Rugao City is the best,while the Rudong City and Hai’an City are the worst.At last,a discussion on how to improve the waterresource guarantee for every district is made
