Abstract: Urban integration is a dynamic process of factor flow and integrated development between cities. The implementation of urban integration is of great significance to coordinated regional development. We took Wuhan Metropolitan Area as the research area and constructed a comprehensive measurement model of the metropolitan area’s urban integration from economic, population, and information flow. We used ArcGIS spatial visualization to analyze the urban integration level and spatial pattern of the Wuhan Metropolitan Area. We inducted the obstacle degree model to explore influencing factors of urban integration. The results showed: (1) Wuhan was the metropolitan area’s economy, population and information centre city. The overall level of urban integration in the Wuhan Metropolitan Area was quite different, and the polarization phenomenon was prominent. (2) The urban integration of the Wuhan Metropolitan Area formed a spatial pattern of “one core, one district, two axes and multiple points”, and it had the spatial characteristics of spatial imbalance, spatial directivity and spatial proximity effect. (3) Infrastructure construction was the key driving force for the urban integration of Wuhan Metropolitan Area, economic development capability was the direct driving force. and residents’ living standards and public service security were the indirect driving force. Based on this study, we put forward some targeted development suggestions, and this paper aims to provide scientific support and case references for the regional construction of urban integration.
