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。
Using methods such as ArcGIS spatial analysis tools and population density models,the spatial differences and spatial model of population growth,and the law of polycentric development from 2000 to 2010based on the 5th and 6th census data in Xi′an city were analyzed.The results showed that population increased differently in different rings and directions in Xi′an city.In generally,the population in city-core and ex-urban decreased in high speed,while the population in sub-urban region increased rapidly.Specifically,population in north and south direction increased fast,but the western and eastern areas increased lower.The population in exurban decreased rapidly while county towns and other important towns gathered quickly.Based on the regression of monocentric population model,it was found that the Clark model can describe population densities well in both urban area and metropolitan of Xi′an city from 2000to2010.Based on regression of multi-nuclear population model,the spatial structures of Xi′an cityhave been transformed from monocentric spatial structure in 2000 to double-nuclear structure(Zhonglou Xiaozhailu)in 2010,however,the polycentric structure has not yet appeared.
