集对分析多元模糊评价法在水资源可再生能力评价中应用

水资源可再生能力受多种因素影响,因素间关系错综复杂,水资源可再生能力综合评价是一项复杂的系统工程.以集对分析理论为基础,用新定元准则、主同、超同和同化度等新概念发展集对分析,建立了一种新的流域水资源可再生能力评价模型—集对分析多元模糊评价模型(MFSPAFM).应用该模型对黄河流域及其上、中、下游典型省份的水资源可再生能力进行了综合评价,并与常规集对分析模型和可变模糊等模型评价结果进行了比较.实例应用显示该模型能够真实地反映水资源可再生能力状况,评价结果更符合客观实际.研究表明,集对分析多元模糊评价模型结构简单,计算简洁,可行有效,适用于水资源可再生能力综合评价.

Multi-Factor Degree Set Pair Analysis Fuzzy Evaluation Model to Evaluation of Water Resources Renewability Ability

The water resources renewability ability integration evaluation is the Systems Engineering which is is influenced by multi-factor,nonlinear relations,and complicated uncertainty. The set pair analysis has been developed by the concepts of the main same,supper same,assimilation degree and the new grades law.The multi-factors degree set pair analysis fuzzy evaluation model(MFSPAFM) has been established and been applied to evaluate the water resources renewability abihty of Yellow River basin.And the result is compare with the results of the routine set pair analysis evaluation model,fuzzy variable set,and so on evaluation models.It is showed that the MFSPAFM is structure simple,calculation easy, result practical and reasonable,and method feasible and reliable and is fit for water resources renewabihty abihty integration evaluation.
