【摘要】：以关天经济区为案例地,运用空间统计工具,将市、县、镇三个尺度的人口空间变化纳入统一的分析框架,探究不同尺度的人口时空格局及影响机制,分析尺度间差异。研究表明:1在人口空间格局上,市级层面西安市是经济区人口分布的核心;县级层面区域人口沿渭河呈带状分布格局;镇级层面人口以西安为中心沿交通轴线向外围递减;2经济区人口格局整体呈现空间集聚趋势,并在各尺度间表现出明显差异。在市级层面,区域人口加速向西安集中;在县级层面,人口主要向地级市市区集中;在镇级层面,出现两种人口集聚路径:一是地级市市区内,人口大量向近郊集聚,中心城区人口快速缩减,郊区化特征明显,二是在市区外围,人口明显向各县城集聚,绝大多数乡镇人口下降。
[Abstract]:Taking Guantian Economic Zone as a case study, using spatial statistical tools, the spatial changes of population on three scales of city, county and town are brought into the unified analytical framework, and the spatial and temporal patterns of population and the influencing mechanism of different scales are explored. The study shows that the population distribution in Xi'an is the core of the population distribution in the economic zone at the city level and the distribution pattern in the Weihe river at the county level. At the township level, Xi'an is the center of population, and the population pattern of the economic zone is decreasing along the traffic axis. The population pattern of the economic zone shows the trend of spatial agglomeration as a whole, and shows obvious differences among the scales. At the municipal level, the regional population accelerates to the concentration of Xi'an; At the county level, the population is mainly concentrated in the prefecture-level urban areas; at the township level, there are two ways of population agglomeration: first, in the prefecture-level urban areas, a large number of people gather to the suburbs, the central urban population shrinks rapidly, and the suburbanization characteristics are obvious. Second, in the urban periphery, the population obviously to the county towns, the vast majority of township population decline.
