【摘要】：基于西安市第五、六次人口普查中的常住人口数据,运用空间分析技术、人口密度模型,分析2000—2010年西安市人口演变的空间差异,总结人口增长的空间模型,揭示人口空间的多中心演化规律。结果表明:十年间西安市人口增长表现出明显的空间差异性,总体形成了中心核心区和远郊区人口减少、近郊区人口明显增加的发展格局。具体而言,南北方向人口快速增长,东西方向人口增长相对滞后,远郊区在人口普遍下降的同时形成了向县城及重点镇集聚的发展态势。人口单中心模型分析发现,西安市人口空间分布基本符合Clark模型,但已出现多中心化迹象。多中心模型分析结果显示,西安市人口空间从2000年的单中心结构逐渐发育为钟楼-小寨路双中心结构,多中心结构尚未形成。
[Abstract]:Based on the resident population data in the fifth and sixth census of Xi'an, the spatial difference of population evolution in Xi'an from 2000 to 2010 is analyzed by using spatial analysis technology and population density model, and the spatial model of population growth is summarized. This paper reveals the law of polycentric evolution of population space. The results show that the population growth of Xi'an city has obvious spatial difference during the past ten years, and the population in the central core area and the far suburbs has decreased, and the population in the near suburbs has increased obviously. In particular, the population grows rapidly in the north and south directions, and the population growth in the east and west directions lags behind. While the population in the far suburbs is generally declining, the development trend towards the county towns and the key towns is formed at the same time. The analysis of population single center model shows that the spatial distribution of population in Xi'an basically accords with Clark model, but there are many signs of centralization. The results of multi-center model analysis show that the population space of Xi'an has gradually developed from the single-center structure in 2000 to the double-center structure of the clock tower and Xiao Zhai Road, and the multi-center structure has not yet been formed.
