基于GIS的石家庄市人口空间分布变动研究

A GIS-based Study on the Spatial Feature of Population Distribution in Shijiazhuang City

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。

Based on the urban population data of Shijiazhuang city in 1982,1993,2001,2005 and 2008, the spatial feature of population distribution were analyzed by population density index and population gravity center under the support of GIS and SPSS. According the fitting results of the distribution of the population densities, the following conclusions can be drawn：（1） The spatial distribution of population is characterized by decreasing population density from interior to exterior;（2） The population gravity centers transit from east county to the center of the city;（3）The Inverse Model can best describe the spatial distribution of population density in Shijiazhuang city.
