本文以北京市第五次、第六次人口普查数据和各街道调查数据为基础，将街道定义为统计常住人口的最小管理单元，并结合空间自相关分析、人口重心和密度模型等研究方法，探讨了2000-2010年北京大都市区外来常住人口的空间结构机制和演化特征。研究结果表明：1北京大都市区外来常住人口的分布在近郊与远郊的过渡地带形成了“增长圈层”，并有向西、北、南三个方向扩展的趋势。2外来常住人口的分布呈现出在整个都市圈内扩散而在特定区域高度集聚的格局，形成了显著的空间集聚结构。人口重心受到外来常住人口向北、向东转移的影响。3北京大都市区外来常住人口的分布主要分布在距广场中心20公里的一圈内。从中心到边缘，人口密度不断增加，在距离中心7公里处达到密度峰值，然后开始下降。非本地常住人口密度的空间模型与常住人口的空间模型不同。克拉克模型被认为是最适合这项研究的。
Based on the fifth and the sixth census data of Beijing and the survey of each neighborhood,this paper defines the streets as the minimum administration unit to count up the permanent population,and combine the research methods as spatial autocorrelation analysis,gravity center of population and density model discusses the mechanism of spatial structure and evolution characteristics of non-native permanent population in metropolitan areas of Beijing from the year of 2000 to 2010. The result is as follows: ① The distribution of non-native permanent population in metropolitan areas of Beijing has formed a 'Growth Circle-Layer ' in the transitional areas between inner suburbs and outer suburbs,and it has had a tendency for expansion to the directions of the west,the north and the south. ② The distribution of non-native permanent population the pattern of diffused in the whole metropolitan areas while the high concentration in particular areas,which forms a significant spatial agglomeration structure. The gravity center of population has been affected by the non-native permanent population to transfer towards north and east. ③ The distribution of the non-native permanent population in metropolitan areas of Beijing is mainly distributed in a circle of 20 kilometers from the centre of Tiananmen Square. From the center to the edges,the population density keeps increasing,which reaches a density peak 7 kilometers away from the center,and then begins to decrease. The spatial model of the non-native permanent population density varies from that of permanent population. Model Clark is regarded as the most suitable one for the research.
