摘　　要：水资源承载能力分析对发现和解决区域水资源问题具有重要意义。针对水资源承载力评价指标维度高、指标权重主观性强等问题,构建基于主成分分析的水资源承载能力评价模型,该模型在尽可能保留评价指标信息的基础上能有效降低指标维度,同时能客观量化不同维度综合指标的权重,此外模型构造不同维度的函数关系,明确给出了不同承载等级的分界线。模型应用于典型南方小流域,结果表明主成分分析方法具有较好的适用性。Water resources carrying capacity analysis has significant meaning for finding and solving regional water resources problem. Aiming at the problems of high dimensions and strong subjectivity in quantifying the weights of water resources carrying capacity evaluation index, a water resources carrying capacity evaluation model based on the principal components analysis method is established. This model can effectively reduce the dimension and quantify the weight of each component objectively on the basis of the retention of the evaluation index information as much as possible. In addition, the model provides classification line for each carrying capacity class by establishing a functional relationship of different dimensions. The suitability of the model is verified by applying it in a typical small basin in southern China.
