2000年~2010年西安市人口空间布局变化研究

Research of population distribution in Xi'an during 2000-2010

基于第五次和第六次人口普查数据,以西安市为例,运用GIS、Geoda等空间分析方法来研究西安市人口空间布局与变化特征。研究发现:(1)西安市人口空间分布圈层差异较大,"东北-西南"轴向扩张特征明显。户籍人口的郊区化和外来人口的局部集聚同时存在。(2)西安市人口局部空间集聚造成"空间马太效应"不断增强,中心城区及相邻的部分近郊区街道共同构成了常住人口、外来人口的高密度集聚中心,东西两侧的远郊区则出现了集中连片的低密度人口洼地,且两类地区均呈现扩大趋势。(3)园区开发、大学城建设、行政中心迁移、老工业区转型以及城市更新改造等因素共同推动了西安市人口布局的演变。

Based on the fifth and the sixth census data, this paper states thepopulation spatial distribution and change characteristics, using GIS andGeoda spatial analysis. We found： （1） there is circle difference in spatialdistribution, and the northeast-southwest axial expansion characteristic isremarkable. The suburbanization of population and the local agglomeration ofthe immigrant population exist simultaneously. （2）the spatial agglomerationcaused the Matthew effect are growing in Xi＇an, the city center and theadjacent part of the suburb street constitute the high density of thepermanent population, the immigrant population. The east and west suburbanareas have low population density depressions contiguous, and two regionsshowed a trend of expansion. （3） Park development, university cityconstruction, administrative center migration, the transformation of the oldindustrial areas and urban renewal and other factors jointly promote theevolution of the population distribution in Xi’ an.
