摘要 基于晋中市的自然环境、资源状况、社会经济和环境条件,选取与环境承载力相关的十四个指标层建立了晋中市资源环境承载力评价体系,采用SPSS技术和AHP层次分析法综合指数评价模型,以各县市为单位计算资源环境承载力的综合值.研究表明:①晋中市资源环境承载力总体处于中等和较低水平,未来的经济发展应该坚持开发与保护相结合,减小对资源的开发力度.②榆次区、寿阳县和左权县承载力等级处于中等水平,这3个县总面积约占晋中市总面积的33.28%,资源开发利用程度较小,发展空间大.③其他8个县承载力等级均处于较低水平,面积约占晋中市总面积的67.72%,开发利用程度大,资源环境承载力面临较大压力,应加大生态建设保护,提高资源环境承载力. Based on the natural environment,resources,socio-economic and environmental conditions of Jinzhong City,14 indicator levels related to environmental carrying capacity were selected to establish the evaluation system of resources and environment carrying capacity of Jinzhong City.Using SPSS and AHP comprehensive index evaluation model to calculate the integrated value of resources and environmental carrying capacity for each county and city.Research shows:①The overall carrying capacity of resources and environment in Jinzhong City is at a moderate level.In the future,economic development should adhere to the combination of development and protection,reduce the development of resources.②Yuci District,Shouyang County and Zuoquan County is at a medium level,three counties accounted for 33.28%of the Jinzhong City,the development and utilization of resources is small with ample room for development.③The capacity of other 8 counties is at a relatively low level,accounting for 67.72%of the total area of Jinzhong City.Due to the large development,the resources and environment carrying capacity are under great pressure,should increase ecological protection moreover improve the carrying capacity of resources and the environment.
