摘要
潜能模型作为测度空间可达性的重要模型,广泛应用于医疗教育、公园绿地等公共设施可达性分析中。以家具物流园为切入点,在物流园区占地面积影响因素的基础上加入物流企业数量因子,构建改进潜能模型测度其空间可达性。同时结合地理信息系统(GIS)插值方法进行可达性等级划分,并在出行时间测算中引入货车限行影响因子。以南康区为例进行家具物流园空间可达性验证分析。结果表明:南康家具物流园区潜能分布较为平衡,中部物流商贸城和红土地物流园作为成熟的物流园其潜能值最大,物流园区空间可达性分布差异不明显,大致呈现出中东部高、周边低的分布格局。
As an important model for measuring spatial accessibility,the potential model is widely used for analyzing the accessibility of public facilities such as medical education and park green space.This paper took the furniture logistics park as the entry point and introduced the number factor of logistics enterprises into the factors affecting the logistics park area,so as to construct the improved potential model to measure its spatial accessibility.At the same time,the geographic information system(GIS)interpolation method was used to classify the accessibility level,and the influence factor of truck restriction was introduced in the measurement of travel time.Then,the furniture logistics park in the Nankang District was studied to verify the spatial accessibility.The results show that the potential distribution in Nankang furniture logistics park is relatively balanced,and the potential values of central logistics trade mart and Hongtudi logistics park as mature logistics parks are the largest.Moreover,the distribution difference of spatial accessibility of the logistics park is not obvious,showing a distribution pattern of high value in the central and eastern parts and low value in the peripheral parts.
