摘要
为了解近几年我国人口分布的变化情况及区域差距,选取了2013—2017年全国31个省、自治区与直辖市的常住人口数据,结合Arcgis与Geoda技术,采用空间自相关分析对全国人口进行区域分布研究。利用等间隔法将人口密度分成7个等级,发现近几年我国的人口分布仍处于不平衡状态,西南地区人口密度有所上升。通过Moran散点图与LISA聚类图发现,全国人口分布存在空间自相关性,“低—低”类型主要分布在西北地区以及西南地区,“高—高”类型主要分布在华东沿海地区。
In order to know the population distribution change situation and regional difference in recent years in China,permanent resident population data of 31 provinces,municipalities and municipalities directly under the central government from 2013 to 2017 is selected,and through combining with Arcgis and Geoda technology,regional distribution of national population is researched through spatial autocorrelation.Density of population is divided into 7 degrees through using uniformly-spaced method.It is found that,in recent years,population distribution in China is still in unbalanced state,and density of population of the Southwest Region increases.Through Moran scatter diagram and LISA cluster diagram,it is found that spatial autocorrelation exists in population distribution in China.“Low-low”type mainly distributes in the Northwest and Southwest District,and“High-high”type mainly distributes in East China coastal regions.
