摘　　要：根据生态位理论、城市生态位衡量城市发展综合水平,利用生态位宽度衡量城市对资源的利用效率,用生态位重叠指数衡量城市间产业相似程度。以陕南三市(汉中、安康、商洛)为实证对象,提出城市综合发展评价模型,从生态位视角计算陕南三市生态位、生态位宽度、生态位重叠指数的大小,分析陕南三市的竞合关系。结果表明,汉中市是陕南城市群发展的核心城市,陕南三市近年来资源利用率均在逐步提高,陕南三市产业结构相似性高,城市发展之间的关系竞争多。并根据结论提出促进陕南城市群发展的建议,以期对陕南三市的统筹发展提供一定的理论借鉴。According to the niche theory and urban niche,the comprehensive level of urban development is measured,the utilization efficiency of urban resources is measured by niche width,and the industrial similarity between cities is measured by niche overlap in⁃dex.Taking three cities in southern Shaanxi(Hanzhong,Ankang and Shangluo)as the empirical objects,this study put forward the evaluation model of urban comprehensive development,calculated the niche,niche width and niche overlap index of the three cities from the perspective of niche,analyzed the competition and cooperation relationship of the three cities in southern Shaanxi.The results show that Hanzhong city is the core city of the development of southern Shaanxi urban agglomeration,the resource utilization rate of the three cities in southern Shaanxi has been gradually improved in recent years,and the industrial structure of the three cities in southern Shaanxi is highly similar,which leads to more competition among urban development.It put forward suggestions for the devel⁃opment of urban agglomeration in southern Shaanxi,so as to provide some theoretical reference for the overall development of the three cities in southern Shaanxi.
