福建省县域收缩城市的识别与格局研究OA北大核心CSTPCD

In this paper,a comprehensive index system is selected to identify shrinking cities in Fujian Province.The comprehensive index system includes four parts:population,economy,social security,and investment and consumption.Meanwhile,this paper uses population and com-prehensive indices to classify the types of shrinking cities,and analyze their spatiotemporal charac-teristics from 2000 to 2020.The results show that:(1)The number of shrinking cities identified by the single population index in Fujian Province is relatively large,forming two shrinkage belts in central and western Fujian;(2)There are many shrinking cities in Fujian Province based on com-prehensive indicators,showing stage and cohesion characteristics,with 92.7%of the counties and urban areas experiencing comprehensive shrinkage from 2000 to 2010,and a slight decrease to 72.7%from 2010 to 2020;(3)The number of shrinking cities in Fujian Province shows a decrea-sing trend during the study period,and with four shrinkage types identified:growth,shrinkage,obvious shrinkage,and severe shrinkage,with no decay type yet appearing;(4)The spatial dis-tribution pattern of urban shrinkage in Fujian Province is similar to the pattern of population shrink-age,focusing on the central and western regions,with only Pingtan and Anxi experiencing shrink-age in the east.Based on the results of comprehensive shrinkage,population loss is the core factor causing the urban shrinkage,while local finance,industrial structure,and consumption vitality al-so exacerbate the process.
