摘要:

人口空间分布区划是进行人口统计数据空间化处理的基础性工作,通过与人口空间分布紧密相关的要素设计算法计算各省及县人口分布特征指数,确定各省人口特征指数重心和区划指数,据此构建三维特征空间,通过计算各省之间的空间距离,根据最小距离法则将全国分为8个人口空间分布特征区域,并对各区基本情况进行了简要分析。

关键词: 人口, 空间分布, 区划

Abstract:

This paper designs a model to calculate an index of population distribution for each county and province. The index is related to the density of population, natural condition, the level of economic development and the density of traffic lines. A population barycenter of a province is defined according to which county index is closest to the provincical one. Then a 3D space of population distribution is established using the index (z) and the coordinates (x, y) of the barycenter. The distance in 3D space is calculated between any two provinces. According to the principle of minimum distance, China is classified into eight regions of population distribution.

Key words: population, spatial distribution, regionalization
