The Study on Spatial Structure of the Network between Chongqing and Adjacent Areas Based on Highway Passenger Flow
摘要
Abstract
Research on urban spatial networks based on"flow"data has become a new paradigm in the assessment of urban spatial connections and the delineation of metropolitan influence areas in urban geography and territorial spatial planning.Research on urban connections in Chongqing focuses primarily on districts and counties within the city's administrative region,utilizing passenger or cargo flow data to study the spatial structure of the network within Chongqing.However,few studies have been conducted on cross-provincial administrative regions between Chongqing and its neighboring areas,which does not align with the actual influence of Chongqing's metropolitan area.Based on highway traffic passenger flow data,this study employs social network and GIS spatial analysis methods to study the urban network spatial structure between Chongqing and its neighboring areas from the perspective of passenger flow connections.The results indicate the following:(1)Chongqing's central urban area serves as the absolute core of the urban network,with Changshou,Jiangjin,and Bishan as important nodal cities.Fuling,Bishan,and Changshou exhibit notable accessibility within the network,while Fuling,Qianjiang,Jiangjin,and Wanzhou play prominent intermediary roles.There are no prominent regional nodes outside Chongqing's administrative area,and the growth poles for the development of the Chengdu-Chongqing Economic Circle need further cultivation.(2)The passenger flow network between Chongqing and its neighboring areas exhibits a three-tiered axial connection,with the overall network displaying a distinct radial characteristic.The urban clusters in northeastern Chongqing form a distinct band-shaped axis along the Yangtze River with Chongqing.The urban clusters in southeast Chongqing and their neighboring areas exhibit radial axes,with relatively weak connections to the central urban area.Some areas in Guang'an and Dazhou have overcome provincial administrative boundaries,and the network hierarchy is distributed according to"4(level 1)+15(level 2)+18(level 3)."(3)The cohesive subgroups between Chongqing and its neighboring areas demonstrate a high degree of geographical proximity,forming a"core-periphery"structure.This reflects the significant influence that factors such as spatial distance and road extensions exercise on the road passenger transport network.Conducting research on the spatial structure of cross-administrative urban networks from the perspective of highway passenger flow holds significant theoretical and practical value for enriching research on the spatial structure of cross-administrative metropolitan areas and promoting the linkage between Chongqing's metropolitan area and its surrounding regions.关键词
