江苏省人口分布的时空动态分析

Analysis on spatio-temporal dynamics of population distribution in Jiangsu

为了探寻江苏省人口分布的时空动态特征以提供人口动态管理的决策依据,该文以2000年第五次人口普查和2010年第六次人口普查数据为基础,应用GIS空间分析功能结合人口地理学方法,对江苏省两次普查的人口分布特征进行分析。结果表明,江苏省人口空间分布不均,存在着苏南、苏中、苏北以及市县之间的差异;人口空间分布不均衡的趋势不断增强,市域与县域人口分布特征存在差异,人口分布呈现出由苏北向苏南转移的特点。

In the paper,in order to search for the characteristic of spatio-temporal dynamics of population distribution in Jiangsu,based on the data of the fifth census in 2000 and the sixth census in 2010,spatial analysis toolbox of GIS and population geography methods were used to analyze the characteristic of population distribution of two census in Jiangsu.The results showed that population spatial distribution is uneven in Jiangsu,the differences exist between the south of Jiangsu,the center of Jiangsu,the north of Jiangsu and the countries,and the uneven trend is growing,meanwhile the characteristic of population distribution in cities and countries are different;the population distribution presents some characteristics that population is transferring from north to south of Jiangsu.
