2000—2010年西安市人口分布与空间结构研究

The Population distribution and spatial structur in Xi'an City between 2000 and 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等空间分析方法来研究西安市人口时空演化特征及其空间结构,以期探索西安市人口的空间重组规律。研究发现:1西安市人口总量增长快,空间分布上圈层分化明显,市区内大部分地区为城市化发育程度成熟的区域,人口郊区化现象显著且程度高,郊区内部差异大;2人口空间分布具有较强的空间集聚特征,人口空间集聚总体趋势在不断增强,中心城区及相邻的部分近郊区街道共同构成了人口高密度集聚中心,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西安市人口分布呈现出"多中心"特征,小寨路街道为发育成熟的人口次中心。

Based on the fifth and the sixth census data,this paper shows the space-time evolution characteristics of the population in Xi＇an City,and explores the population of Xi＇an spatial reorganization law,using GIS and geoda spatial analysis. It is found：1The total population of Xi＇ an City is growing fast and it is obvious that there is circle difference on spatial distribution. In most areas of the city,the development degree of urbanization is mature,while the phenomenon of population suburbanization is significant and the degree is high. In the suburbs,the internal differences of the population is remarkable; 2the population spatial distribution has a strong positive correlation,the overall trend of population spatial agglomeration is growing. The city center and the adjacent part of the suburb street constitute the regional center of high population density together,and the outer suburbs have emerged the concentrated low density of population contrastly. However,the trend of the two regions is expanding largely; 3 the distribution shows the characteristics of ＂Polycentric population spatial＂structure,the Xiao Zhai Street is developing into the secondary population center.
