摘　　要：通过城市中心职能强度指数分析,应用和改进潜力模型对唐山市各区、县、市及经济开发区的可达性进行综合测算和空间差异特征分析。结果表明:唐山市市域城市可达性及经济联系强度分布不均;城市圈层状空间分布结构正在形成。文章基于城市可达性和经济联系强度的空间差异特征,揭示了唐山市区域空间和交通网络结构中存在的问题,解释了城市经济水平、发展模式以及地理区位对可达性空间差异的作用。According to the analysis of urban fonction intensity index, the potential model, which is used to implement the urban accessibility composite measure and spatial differences analysis in Tangshan city, is applied and improved to this paper. The result showed that, the degree of urban accessibility and economic connection intensity in Tangshan city are inhomogeneous; The spatial patterns of urban accessibility and economic connection intensity in Tangshan city reveal a spatial pattern distribution of spheres structure. According to the spatial pattern distribution rule of accessibility and economic connection intensity, this paper revealed the problem of Tangshan city＇s spatial pattern structure and traffic network structure, explained the role that economic level, development model and location playing in the difference of spatial accessibility.
