云南省25个边境县(市)人口分布时空格局演变分析(1990—2010)

An Analysis of Population Distribution Spatial and Temporal Pattern Evolution of the 25 border counties(cities) in Yunnan Province(1990-2010)

用统计分析、GIS空间分析等方法探讨了1990—2010年云南省25个边境县(市)人口的时序变化、空间分布变化以及分布格局。结果表明,从1990年到2010年的20年间,云南省25个边境县(市)人口总量持续增长,城镇人口比重直线上升,少数民族人口增长率略低于汉族人口增长率。在空间分布上,人口分布不均,差异明显;城乡人口高度集中:民族分布形态单一。云南边境沿线的人口格局总体上反映了边境县(市)人口空间分布与区城经济发展、区住条件等空间差异的显著相关性。

Using statistical analysis and GIS spatial analysis,This paper analyzes Population Distribution Spatial and Temporal Pattern Evolution of the 25 border counties （cities） in Yunnan Province （1990-2010）. The analysis showed that the total population continued to growth ,the urban population has continued to rise,the minority population growth rate was slightly lower than the Han populations from the 20 years between 1990 to 2010. On the spatial distribution,population is unevenly distributed,urban and rural population is highly concentrated,and the ethnic distribution pattern is single. This reflects the significant correlation of spatial difference for the population spatial distribution,regional economic development and geographic conditions in the border counties （cities） of Yunnan Province.
