西藏自治区人口空间分布模式研究

Study on the Patterns of Spatial Population Distribution in Tibet

人口的空间分异是区域差异的客观反映,探讨区域人口空间分布规律是产业合理布局、小城镇建设、资源优化配置等的理论基础,也是区域人口、资源与环境协调发展的基础性研究.该文将空间统计分析与GIS相结合,深入探讨了西藏人口空间分布模式.研究表明,西藏人口空间分布呈现"西北—东南"模式,存在显著的空间集聚现象,四种类型的空间关联在空间分布上具有明显的规律性.利用空间统计分析方法能够扩展和加强GIS的空间分析功能,从而更深入地探索、分析、处理和解释人口分布的空间模式与空间关联,为进一步研究空间模式的发生尺度和塑造该模式的空间过程奠定基础.

The population spatial different is a reflect of district difference objectively, discussing the spatial distribution rule in region population is rationale for the industrial reasonable layout,small cities construction and the resources optimization disposition and so on, it is also basic research of the region population, the resources and the environment coordinated development. In this paper, Spatial statistical analysis and GIS are combined to analyze the patterns of spatial population distribution of Tibet. The results show that spatial population distribution of the area is characterized by the ＂northwest vs southeast＂ pattern;there are significant phenomena of spatial clustering in the study area, the spatial association of four categories have obvious regularity in terms of spatial distribution. The research indicates that spatial analysis function of GIS can be widened and strengthened by spatial statistical analysis,allowing for the deeper exploration, analysis, manipulation and interpretation of spatial patterns and spatial association of population distribution. This provides a foundation for further study on scales that spatial patterns occur and on spatial processes which form these patterns.
