摘　　要：为遵循水资源可持续发展原则,解决流域内水资源供需矛盾。寻求一种物理意义明确、简单、实用的评价模型来精确反映流域内实际水资源可再生能力等级具有极为重要的理论研究价值和现实意义。为此,在建立流域水资源可再生能力的复合模糊物元和差平方复合模糊物元基础上,结合欧式贴近度的概念,并通过采用反映指标特征值之间差异性的统计参数-变异系数作为评价指标权重,实例介绍了该方法的具体应用,并与其它几种方法比较,结果表明该方法实用、可行。In order to follow the water resources sustainable development and solve the contradiction between supply and demand of water resources in a watershed,seeking a clear physical meaning,simple and practical of evaluation model to accurate reflect actual water resources reproducible ability grade in a watershed have a very important theoretical research value and reality significance.Therefore,this paper based on composite fuzzy matter element and differential square composite fuzzy matter element of the establishment of watershed water resources reproducible,Combined with the concept of the European approach degree,adoptting the different to reflect the specific or feature values of evalution indexes as the weight of evalution indexes,The example describes the specific application of the method,compares other methods and finds that the model ispractical feasible.
