西北中心城市人口演变与商业空间协同路径研究OA

Urbanization is a pivotal factor influencing the sustainable and stable development of China's economy and society.To advance theoretical research on population urbanization in Northwest China,this paper takes Xi'an as a case for study.Utilizing census data and ArcGIS,the paper conducts a visual analysis on the spatiotemporal evolution and spatial characteristics of population urbanization.Furthermore,by integrating POI data of commercial outlets,it investigates the coupling relationship between commercial spatial patterns and population urbanization.The findings reveal that:①from 1990 to 2020,the total population of Xi'an nearly doubled,exhibiting a shift from initial aggregation towards inner urban areas to subsequent polycentric distribution.②The spatial distribution of the population in Xi'an demonstrates distinct ring-layer differentiation,with the inner and middle rings serving as the primary zones accommodating population growth.③The spatial pattern of commercial outlets in Xi'an follows a model of"one-axis,multi-core"model,which aligns broadly with the city's overall population distribution.Additionally,the distribution patterns of different commercial types exhibit spatial variation.
