摘　　要：用变异系数法及层次分析(analytic hierarchy process,AHP)法计算组合权重,并将灰色关联分析法中的灰关联系数应用于模糊综合评价模型中的模糊关系矩阵,结合定性、定量分析,对模糊综合评价模型进行改进。将改进后的模糊综合评价法应用于江阴市水资源承载力评价,结果表明,与传统模糊综合评价法相比,综合评价结果相同,但是计算结果对于各个评价等级的隶属度差距减小,降低了主观影响,说明改进后的评价方法在区域水资源承载力评价中应用良好。The coefficient of variation method and the analytic hierarchy process （ AHP ） method were used to calculate combined weights. The grey correlation coefficient of the grey correlation analysis method was applied to the fuzzy relation matrix in the fuzzy comprehensive evaluation model. Combined with qualitative and quantitative analyses, the fuzzy comprehensive evaluation model was modified. The improved fuzzy comprehensive evaluation method was used to evaluate the water resources carrying capacity of Jiangyin City. The evaluation results agreed with those of the traditional fuzzy comprehensive evaluation method. In addition, the degree of membership with regard to various evaluation grades showed an insignificant difference, and the subjective effect was reduced, indicating that the improved evaluation method is applicable to regional water resources carrying capacity.
