阿拉尔市人口空间分布特征及其影响因素分析

Analysis on the Spatial Distribution Characteristics of Population and Its Influencing Factors in Alar City

基于2017年《新疆兵团第一师阿拉尔市统计年鉴》、《新疆生产建设兵团统计年鉴》的统计数据,以阿拉尔市城区及各团场为研究单位,选取人口密度作为主要研究指标,运用空间自相关性、主成分分析等分析方法,结合GIS技术,运用ArcGIS、OpenGeoDa和R软件探讨阿拉尔市人口空间分布特征及影响因素。结果表明:2017年阿拉尔市人口大多数集中在阿拉尔城区,周围团场人口分布较城区稀疏,总体呈现出交通越便利,人口分布越集中的空间分布格局;阿拉尔市人口存在一定的空间相关性;人均GDP、第三产业人口占行业人口比重为影响人口空间分布的主要因素。

Based on the statistical data of the 2017“Statistical Yearbook of the First Division of Xinjiang Corps”and“the Statistical Yearbook of Xinjiang Production and Construction Corps”,select population density as the main research indicator.Taking the group field as the research unit,using spatial auto-correlation,principal component analysis and other analytical methods,combing with GIS technology,using ArcGIS,OpenGeoDa and R software,exploring the spatial distribution characteristics and influencing factors of population in Alar city.The results show that:in 2017,the majority of Alar’s population was concentrated in the urban area of Alar city,the population around the group is sparsely distributed than the urban area.In general,the spatial distribution pattern of the more convenient transportation and the more concentrated population distribution is presented;there is a certain spatial correlation among the population of Alar city;the GDP and the proportion of the tertiary industry to the proportion of the industry's population are the main factors affecting the spatial distribution of population.
