摘　　要：基于DPSIRM模型,结合太原市的水资源现状,构建了包含驱动力、压力、状态、影响、响应、管理6个子系统,选取15个评价指标,运用熵权TOPSIS评价模型对2011-2018年太原市水资源承载力进行评价。同时,采用障碍度模型对影响水资源承载力的关键因素进行分析。结果表明:在研究期间内,太原市水资源承载力2011-2012年为超载状态,2013-2018年为临界超载状态;2015-2018年太原市水资源承载力快速提升主要是由于状态、管理子系统的提升;城镇人均生活用水量和地下水超采系数两项指标在未来还有很大的提升空间。Based on the DPSIRM model and combined with the status quo of Taiyuan’s water resources,six subsystems including driving force,pressure,status,impact,response,and management are constructed,from which 15 evaluation indicators are selected,and then the entropy TOPSIS evaluation model is used to evaluate the water resources carrying capacity of Taiyuan City from 2011 to 2018.At the same time,the obstacle degree model is adopted to analyze the key factors affecting the carrying capacity of water resources.The results show that during the study period,the water resources carrying capacity of Taiyuan City was overloaded from 2011 to 2012 and improved to the critical point of overloading from 2013 to 2018.The rapid increase in the water resources carrying capacity of Taiyuan City from 2015 to 2018 was mainly due to the improvement of status and management subsystems.there is still much room for improvement in the two indicators of urban per capita domestic water consumption and groundwater overexploitation coefficient in the future.
