陕北供水网络方案的多方法综合评价

摘要

随着地区水资源供需矛盾的日益加剧,作为我国重要能源基地,陕北地区的供水网络建设及建设方案的综合评价成为缓解水资源短缺亟需解决的关键问题.本文通过层次分析法、熵权法和组合权重等多方法确定陕北供水网络方案评价指标的权重,采用层次分析法、灰色综合评价法和优势比较法开展供水方案的多方法综合评价研究,以陕北地区四种供水方案为例,验证了多种方法综合评价的优越性.结果表明:三种评价方法的评价结果一致,并结合实际情况推荐方案二为陕北供水网络的最优方案.研究成果为陕北供水网络评价指标权重确定及其综合评价模型建立了提供理论依据,对于陕北水资源优化配置方案的实施具有重要的现实意义和应用价值.%With the increasing contradiction between supply and demand of regional water resources, as an important energy base in China, the water supply network construction and the comprehensive evaluation of construction schemes in northern Shaanxi have become the key problem to alleviate the shortage of water resources.In this paper, the weights of the evaluation indexes of northern Shaanxi water supply network schemes are determined by the analytic hierarchy process (AHP), entropy weight method and combined weights.By using AHP, grey comprehensive evaluation method and superiority comparison method to carry out the comprehensive evaluation research on water supply scheme, the paper verifies the superiority of the comprehensive evaluation of various methods with the example of the four kinds of the water supply scheme of northern Shaanxi.The results show that the evaluation results by three evaluation methods are consistent with the actual situation by the recommended best scheme for the water supply network in northern Shaanxi is the scheme 2.The research results provide a theoretical basis for the weight determination of the evaluation index and the comprehensive evaluation model of the water supply network in northern Shaanxi, which is of practical significance and application value for the implementation of the water resources optimal allocation scheme in northern Shaanxi.
