摘　　要：基于已有太原市水资源承载力评价结果,结合水量、水质、水域、水流各维度临界超载/超载原因分析和太原市水资源现状,定性分析太原市水资源承载力的驱动因子;采用主成分分析法、层次分析和熵权组合赋权法,定量识别影响太原市水资源承载力的驱动因子;综合定性分析与定量识别驱动因子方法的各自优势,取其交集,将共同影响因子作为太原市水资源承载力的主要驱动因子。结果表明,影响太原市水资源承载力各维度的主要驱动因子分别为:①水量维度:降水量、人均水资源占有量、引入水占用水比、地下水开采系数、农田灌溉水有效利用系数、万元工业增加值用水量、污水利用率;②水质维度:水功能区水质达标率、劣Ⅴ类水质占比;③水域维度:水土流失治理率;④水流维度:河流生态补水比例。研究结果可为太原市水资源承载力提升方案的制定提供参考。Utilizing the existing evaluation results of the water resources carrying capacity of Taiyuan City,this paper qualitatively analyzed its driving factors of the city,which was based on the analysis of the critical overload/overloading causes of various dimensions including quantity,quality,domain and flow and the consideration of the current situation of water resources in Taiyuan City.The paper also quantitatively identified the driving factors influencing the water resources carrying capacity of Taiyuan City with a combination weighting method of principal component analysis,analytic hierarchy process and entropy weight method.Further,making full use of the respective advantages of qualitative analysis and quantitative identification of driving factors,the paper took the common influencing factors as the main driving factors of the water resources carrying capacity of Taiyuan City.The results indicated that the main driving factors influencing the various dimensions of water resources carrying capacity in the city included the followings:①water quantity dimension:precipitation,per capita water resources,ratio of imported water to consumed water,groundwater extraction coefficient,coefficient of effective utilization of farmland irrigation water,water consumption per 10000 yuan of industrial added value and wastewater utilization rate;②water quality dimension:water quality compliance rate of water function zone,proportion of water quality inferior to Grade V;③water domain dimension:soil erosion control rate;④water flow dimension:proportion of river ecological water replenishment.The research results can provide references for the plan formulation of improving water resources carrying capacity in Taiyuan City.
