摘　　要：在城市群发展过程中逐渐暴露出核心城市驱动能力不足及局部发展不均衡等问题,文章运用地理信息系统(Geographic Information System,GIS)空间分析方法、复杂网络理论及引力模型,探讨城市群内部各城市间的空间相互作用。实验结果表明,研究期间,城市群内部总引力分布不均衡,空间相互作用力呈现幂律分布及重尾效应。成都市与重庆市主城区作为核心区域,展现出“双核发展”等空间特征。通过对历史统计数据分析,成渝城市群的空间引力网络呈现“双核闭合环+中部塌陷”的结构,并伴随“局部引力团簇集聚”现象,表明其空间引力格局正经历复杂的演化过程。In the process of urban agglomeration development,problems such as insufficient driving capacity of core cities and uneven local development have gradually been exposed.Therefore,this study uses geographic information system(GIS)spatial analysis methods,complex network theory,and gravity models to explore the spatial interactions between cities within urban agglomerations.The experimental results indicate that during the study period,the total gravity distribution within the urban agglomeration was uneven,and the spatial interaction force exhibited a power-law distribution and heavy tailed effect.Chengdu and the main urban area of Chongqing,as core regions,exhibit spatial characteristics such as“dual core development”.Through analysis of historical statistical data,the spatial gravity network of the Chengdu Chongqing urban agglomeration presents a structure of“dual core closed loop+central collapse”,accompanied by the phenomenon of“local gravity cluster aggregation”,indicating that its spatial gravity pattern is undergoing a complex evolutionary process.
