Research on spatial characteristics and development strategies of urban agglomeration from multi-dimensional perspectives——A case study of Wuhan Metropolitan Area
Urban integration is an important purpose for metropolitan area development,and quantifying the spatial characteristics of urban integration in metropolitan areas is critical for achieving coordinated growth.This paper used the Wuhan metropolitan area as an example,with several perspectives including population,transportation,economic and industrial,and public services.A variety of data sources were utilized,including Direction API,to optimize the analysis framework for urban integration.The results showed that:①"Rapid expansion of a core and steady expansion of multiple scattered points"was the spatial characteristics of Wuhan Metropolitan Ar-ea's built-up area.②There were considerable isochronous deformation and isochronous enclaves on the public transport isochronous circle,and a spatial feature of"high in the north and low in the south,high in the center and low around"on the driving isochronous circle.A few locations within the"Wu-E-Huang-Huang"core still required a lengthy commute,falling short of the"one hour com-muting"target.③A"dense center and scattered surroundings"pattern was evident in the distribution of population density,while a"high in the east and low in the west"spatial characteristic was evident in the intensity of cross-city population flow.Wuhan was the primary choice for cross city mobility in surrounding cities.④The degree of industrial specialization and sophistication in metropolitan area was increasing continuously.⑤Public service facilities were distributed unevenly,with"one core,multiple centers"as the spatial pattern.Certain facilities required configuration and optimization.Finally,spatial development strategies were offered.
