【摘要】：选取河北石家庄市1982、1993、2001、2005和2008年5个年份的人口数据资料,在地理信息系统(GIS)和SPSS软件支持下,从人口密度、人口重心两个方面系统分析了石家庄人口空间分布特征,通过人口空间分布模型的回归拟合,找出符合石家庄市人口变化规律的密度模型。结果显示:石家庄市人口密度仍然呈现出由中心向外围渐低的特点;人口重心主要集中在城市东部郊县并有向中部市区迁移的趋势;符合石家庄市人口空间分布的密度模型为倒数函数。这一结果表明城市中心区仍然是石家庄市人口集中区,人口分布郊区化现象尚不明显。
[Abstract]:With the support of GIS (Geographic Information system) and SPSS software, the spatial distribution characteristics of population in Shijiazhuang were systematically analyzed in terms of population density and population center of gravity by selecting the population data data of Shijiazhuang City in 1982-1993 / 2001,2005 and 2008, supported by GIS (Geographic Information system) and SPSS software. According to the regression fitting of population spatial distribution model, the density model which accords with the law of population change in Shijiazhuang City is found. The result shows that the population density of Shijiazhuang City is still decreasing from the center to the periphery. The population center of gravity is mainly concentrated in the suburban counties in the eastern part of the city and tends to migrate to the central urban area, and the density model, which accords with the spatial distribution of population in Shijiazhuang, is the reciprocal function. The result shows that the central area of the city is still the population concentration area of Shijiazhuang. The phenomenon of suburbanization of population distribution is not obvious.
