摘　　要：利用北京市第六次人口普查数据,在对人口统计数据进行空间化处理的基础上,分析了城市人口密度分布的统计特征及其空间自相关性,充分证明了北京市人口密度分布具有非常强烈的空间自相关性,并已经凸显出城市人口密度多核心分布模型的特征;在对人口统计数据进行格网化处理的基础上,分析了6种不同尺度下北京市人口密度空间分布的统计学特性和空间自相关性,证明了北京市人口密度的空间分布具有尺度特性;本文进一步对尺度特性影响下的人口密度空间分布特性空间自相关性进行了对比研究,从而揭示出空间自相关性与尺度变化间的规律。Upon the data from the sixth national census, firstly this paper analyzes the spatial distribution in population statistics and the pattern of population distribution. The result shows that the population density in Beijing has a strong spatial autocorrelation, and accords with the feature of population density multiple nuclei model. Then we analyzes the statistical characteristics and spatial autocorrelation characteristics of Beijing's population density spatial distribution insix different scale. The result shows that the spatial distribution of Beijing's population density has scale characteristic; to move forward a single step, we conduct a comparative study on the statistical characteristics and spatial autocorrelation characteristics in six different scale, in order to discover the pattern between the Spatial auto-correlation and the study scale.
