摘要
采用人口密度、人口结构化指数和空间自相关模型,借助GIS软件平台,对山东省的人口分布及其空间自相关性进行分析.结果表明:(1)山东省各地市之间人口总数差距显著,各县区之间人口密度差别较大,呈现多个同心环、西南高东北低的态势.(2)山东省人口分布的集中指数为0.1621,不均衡指数为0.0098,人口分布的集中化趋势不明显,各地市内人口分布较均衡.(3)山东省人口分布的全局莫兰指数为0.2174,人口空间分布不是随机过程,有较强的空间自相关性;依据局部莫兰指数和山东省省情,将全省人口分布划分为高密度—高度扩散型、高密度—中度扩散型、低密度—低度扩散型、高密度—高度集聚型、高密度—低度集聚型和低密度—离心型等六种类型.
Using population density,imbalanced index,concentration index and spatial auto-correlation analysis model,the population distribution pattern of Shandong Province and its spatial auto-corelation have been analyzed based on GIS soft.The results show that：（1）the population quantity and its density of counties is quite different,showing multiple concentric rings and higher density in the southwest and lower in northeast;（2）the concentration index and imbalanced index of Shandong Province is 0.1621 and 0.0098 respectively,indicating that the tendency of concentration is not obvious and the population distribution is balance within each county;（3）the global Moran＇s I of Shandong Province is 0.2174,suggesting the population distribution is not a random process and the distributional pattern has a stronger spatial autocorrelation.The area of Shandong Province is divided into six subtypes according to LISA and additional information,i.e.high density and high diffusion,high density and middle diffusion,low density and low diffusion,high density and high centralization,high density and low centralization,low density and scatter.
