通过分析水资源承载能力的主要影响因素,以武汉市为例,提出了武汉市水资源承载能力评价指标体系,合理确定指标标准值,并建立了基于可变模糊识别的水资源承载能力评价模型,采用可变模糊集理论计算样本指标对各级别指标标准值区间的相对隶属度,指标权重通过主客观相结合途径确定,即准则层指标权重采用层次分析法确定,指标层指标采用熵值法确定。结果表明,武汉市水资源承载能力属于中等水平。

By analyzing the main influencing factors of water resources carrying capacity, taking Wuhan as an example, this paper proposes an evaluation index system of water resources carrying capacity in Wuhan, and determines the standard value of the indexes rationally. A water resources carrying capacity evaluation model based on variable fuzzy recognition , The variable fuzzy set theory is used to calculate the relative membership degree between the sample index and the standard value interval of each index. The index weight is determined through the combination of subjectivity and objectivity, that is, the index weight of the criterion layer is determined by the analytic hierarchy process. determine. The results show that the water resources carrying capacity of Wuhan belongs to the medium level.
