摘　　要：以京津冀地区为案例,采用人口密度和交通可达性两个指标,基于10 km格网数据将京津冀地区的空间结构划分为内层中心空间、外层中心空间、人口稠密的过渡空间、人口稀薄的过渡空间、人口增长的边缘空间、人口稀薄的边缘空间六种类型,结果表明:1中心空间以占9.87%的土地面积集聚了31.39%的人口,边缘空间以占75.42%的土地面积集聚了47.95%的人口,中心空间的人口密度是边缘空间的4.97倍。2中心空间主要集中在北京和天津的市辖区以及保定和廊坊的部分市辖区内。边缘空间主要集中在京津冀地区的北部、西部和南部,这些地区以山区和粮食主产区为主。该格局反映了这一地区资源环境与经济社会相耦合的基本特点。3比照主体功能区划方案,中心空间和过渡空间与开发类地区的拟合度达61.6%,边缘空间与保护类地区的拟合度达72.1%,两者具有较好的一致性。This paper used the indexes of population density and transportation accessibility to classify the spatial structure of Beijing-Tianjin-Hebei region into six types including internal core space, external core space, transitional space with dense population, transitional space with sparse population, periphery space with increasing population and periphery space with sparse population. The results are illustrated as follows： 1）The core space agglomerated 31.39% of population in 9.87% of land area while the periphery space agglomerated 47.95% of population in 75.42% of land area. The population density in core space is 4.97 times as that in periphery spaces. 2）The core space is mostly distributed in the municipal district of Beijing and Tianjin and part of municipal district in Baoding and Lang fang, and the periphery space is mainly distributed in the north, west and south of Beijing-Tianjin-Hebei region and most of them are mountain area and main grain production area, which reflects the basic feature that the resource environment is coupled with the economic society in this area. 3）Compared with the Major Function Oriented Zoning scheme, the fitting degree between the core space, the transitional space and the development-oriented functional zone reaches 61.6%, and the fitting degree between the periphery space and the protection-oriented functional zone is up to 72.8%, which shows that the two schemes have a good consistency.
