近年来上海市人口分布变动的空间特征分析

通过对2000-2003年上海市乡镇人口密度变化率的空间相关性分析,发现上海市近几年人口分布空间变动格局表现为以中心城区为中心的环状分布模式,中心城区和远郊区人口密度变化小、人口增长缓慢,而近郊区人口密度变化大、人口增长迅速.全市人口密度变化率存在着显著的空间集聚现象,4种类型的空间关联在空间分布上具有明显的规律性.研究结果表明,目前上海市人口郊区化趋势明显,高人口密度区域在不断向外扩张,由此可以判断未来上海人口分布的区域变化方向.

An Analysis of Spatial Features of Population Distribution Alteration in Recent Shanghai

This paper makes an analysis of the situation of population distribution in Shanghai during the period from 2000 to 2003.While using the spatial autocorrelation method to analyze population density of villages and towns,it is found that the spatial population distribution of the city is characterized by an increasing ring of population surrounding the central zone of Shanghai.The research result also indicates that Shanghai's population suburbanization is developing very quickly and a lot of near suburbs will become highly-density regions.Population distribution has increasingly become related to economic,traffic and other social development factors.
