可变模糊评价法及在水资源承载能力评价中的应用

Variable fuzzy assessment method and its application in assessing water resources carrying capacity

本文在笔者建立的可变模糊集理论基础上,提出可变模糊评价模型与方法,该方法能够科学、合理地确定样本指标对各级指标标准区间的相对隶属度、相对隶属函数,并且能够通过变化模型及其参数,合理地确定出样本的评价等级,提高对样本等级评价的可信度。最后将该方法应用于淮河流域水资源承载能力的综合评价。应用实例表明,该模型计算简便,评价结果可信度高。

Based on the theory of variable fuzzy set suggested by the authors, the method and corresponding model for variable fuzzy assessment are established. This method can reasonably identify the relative membership degree and relative membership function between the sample index and standard interval of each level index and properly determine the assessment level of each sample by varying the model and its parameters, so that the reliability of assessment can be improved. The proposed method is applied to assess the water resources carrying capacity of Huaihe River basin. The case study verifies that the method and corresponding model are reliable and easy to be used.
