【摘要】 该文将空间统计分析与GIS相结合,探讨天水市人口空间分布模式。研究表明,天水市人口空间分布呈现"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。更多还原

【Abstract】 In this paper,spatial statistical analysis and GIS are combined to analyze the patterns of spatial population distribution of Tianshui City in Gansu Province.The results show that,spatial population distribution of the city is characterized by the“northwest vs.southeast” pattern;there are significant phenomena of spatial clustering in the study area;local version of MoranI is particularly useful for decomposing the pattern of spatial association into four categories,which have obvious regularity in terms of spatial distribution.Also,this 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.更多还原
