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水资源保障能力现状评价的准则层,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:南通市现状保障能力总体处于中等,从分类保障情况看,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,而如东和海安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进行了一定讨论。
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 indicator system of water resources guarantee ability evaluation was constructed for Nantong City.The hierarchy analysis and expert grading method were used to determine the weights of each indicator,and weight average methodology was used to get the evaluation result.Results demonstrated that the water resources guarantee ability of Rugao City is the best,while the ability of Haian and Rudong Counties are the worst of all.At last,a discussion of how to improve the water resources guarantee ability was made.
