Spatial allocation,coverage capacity,and accessibility of Automated External Defibrillators(AFDs)in Xiamen City was investigated,using kernel density,buffer zone geospatial analysis,and the Gaussian two-step floating catchment area model,and integrated with data ofpopulation distribution,points of interest,and geographic information of Xiamen City.The results indicate that the AEDs in Xiamen City exhibit a multi-tiered center-periphery spatial distribution pattern with significant differences in facility density between central urban areas and emerging development zones,which leads to an uneven spatial distribution.AEDs in Xiamen are distributed across a diverse range of locations,demonstrating good overall spatial coverage capability.In addition,there is a negative correlation between accessibility level and population density that about 65.39%of statistical areas are accessibility blind areas.It is suggested that Xiamen City should implement condition-specific optimization strategies for AFDs allocation,while allowing a moderately radical approach based on risk assessment,so as to further improve its coverage capability and accessibility.
