Spatial agglomeration characteristics and population adaptability of urban medical resources in Xi'an
The rational and effective allocation of medical resources constitutes a crucial aspect of contemporary urban public space governance.Employing the framework of adaptability theory,an analysis framework to examine the spatial adaptability between urban medical resources and residential populations is constructed.Using Xi'an main urban area as a case study and leveraging point of interest(POI)data on medical resources,the research employs kernel density analysis,Ripley's K function,location correlation,and Gaussian two-step floating catchment area method to explore the spatial agglomeration modes,scale thresholds,and spatial adaptability relationships with population scale of urban medical resources in Xi'an.Results reveal that urban medical resources in Xi'an exhibit a typical"core-periphery"structure and demonstrate a dependence on the main axis of urban development,with significant agglomeration effects observed in high-level development zones and satellite cities with CBD characteristics.Moreover,the characteristic scales corresponding to peak intensity of various medical resources are consistent,typically representing about 1/4 of the corresponding circle diameter when abstracted into circular areas of equal size.Additionally,the bidirectional location correlation model between urban medical resources and residential communities demonstrates an"asymmetric"structure,with significant leading effects of large-scale public medical resources in population allocation.Overall,the adaptability relationship between urban medical resources and population scale in Xi'an follows a circle decay structure of"strong center,weak periphery",with different types of medical resources exhibiting differentiated characteristics in various urban circles.This reflects the compensation substitution effect and its spatial manifestation among hierarchical medical resource diagnosis and treatment systems under the dual allocation of urban macro planning and market resources.
