【摘要】：基于西安市第五、六次人口普查中的常住人口數(shù)據(jù),運(yùn)用空間分析技術(shù)、人口密度模型,分析2000—2010年西安市人口演變的空間差異,總結(jié)人口增長的空間模型,揭示人口空間的多中心演化規(guī)律。結(jié)果表明:十年間西安市人口增長表現(xiàn)出明顯的空間差異性,總體形成了中心核心區(qū)和遠(yuǎn)郊區(qū)人口減少、近郊區(qū)人口明顯增加的發(fā)展格局。具體而言,南北方向人口快速增長,東西方向人口增長相對(duì)滯后,遠(yuǎn)郊區(qū)在人口普遍下降的同時(shí)形成了向縣城及重點(diǎn)鎮(zhèn)集聚的發(fā)展態(tài)勢(shì)。人口單中心模型分析發(fā)現(xiàn),西安市人口空間分布基本符合Clark模型,但已出現(xiàn)多中心化跡象。多中心模型分析結(jié)果顯示,西安市人口空間從2000年的單中心結(jié)構(gòu)逐漸發(fā)育為鐘樓-小寨路雙中心結(jié)構(gòu),多中心結(jié)構(gòu)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.
