The Chengdu-Chongqing Economic Circle is an important center for promoting economic growth in the western region. Clarifying the driving force and restrictive factors of the urbanization development in Chengdu-Chongqing area is conducive to the further development of the region. Firstly, this study uses geospatial information to describe the resource consumption characteristics of the Chengdu-Chongqing Economic Circle. Then, Moran index has been used to test the spatial agglomeration relationship. Finally, the Chengdu-Chongqing Economic Circle is classified according to the characteristics of natural resource utilization and spatial relations. The results show that (1) the relationship between the comprehensive utilization of natural resources and urbanization in the Chengdu-Chongqing Economic Circle is high in the east and low in the west, and the two places jointly drive the development of the north and the south. (2) From 2015 to 2020, the comprehensive utilization capacity of natural resources in the core area on the west side decrease, and the core area on the east side increase. Urbanization in the north and south is slow, and the direct utilization capacity of natural resources needs to be improved. (3) The city with the best coordination relationship between comprehensive utilization of natural resources and urbanization is on the periphery of the core cities of the Chengdu-Chongqing Economic Circle, and the protection and management measures of the core cities for natural resources do not match their urbanization level.
成渝经济圈是推动西部地区经济增长的重要中心。厘清成渝地区城市化发展的动力和制约因素,有利于该地区的进一步发展。首先,本研究利用地理空间信息描述成渝经济圈的资源消耗特征。然后,利用 Moran 指数检验空间集聚关系。最后,根据自然资源利用和空间关系的特点对成渝经济圈进行分类。结果表明:(1)成渝经济圈自然资源综合利用与城市化之间的关系呈东高西低,两地共同带动了北、南的发展。(2)2015 年至 2020 年,西侧核心区自然资源综合利用能力下降,东侧核心区增加。南北城市化进程缓慢,需要提高自然资源的直接利用能力。(3)自然资源综合利用与城市化协调关系最好的城市位于成渝经济圈核心城市的外围,核心城市对自然资源的保护和管理措施与其城市化水平不匹配。
