为摸清2000—2013年贵阳市土地利用强度的空间分布规律及变化趋势，通过遥感解译、系统网格采样和半变异函数模型分析，采用普通克里金空间内插技术，对比分析贵阳市2000年、2005年、2010年和2013年 4 个时期土地利用强度的空间异质性。结果表明：2000—2013年贵阳市土地利用强度存在较为明显的空间异质性，2000—2010年土地利用强度空间结构比率 C 0／（C 0＋C）分别为0．400、0．342和0．255，属于中等程度的空间自相关性；2013年土地利用强度 C 0／（C 0＋C）为0．238，属于强烈的空间自相关性，且空间自相关程度逐年增强；贵阳市土地利用强度空间异质性的产生主要是由地形、地貌等结构性因素引起，同时也受一定程度人类活动等随机因素的影响。

Taking Guiyang as research area and using ordinary kriging spatial interpolation methods, the spatial heterogeneities of land-use intensity of Guiyang in 2000,2005,2010 and 2013 were discussed through land-use remote sensing mapping,sampling and grid system and geostatistics method based on semi-variogram.Results:land-use intensity of Guiyang within research periods is featured with the spatial heterogeneity of distinction;furthermore,the ratios of spatial structure of land-use intensity [C 0/(C 0 +C)]in 2000-2010 respectively serve as 0.400,0.342 and 0.255,which belong to the medium degree of greater spatial autocorrelation;the ratios of spatial structure of land-use intensity [C 0/(C 0 +C)]in 2013 serve as 0.238,belongs to the strong spatial autocorrelation,and yearly enhancing.All above prove that the existence of the spatial heterogeneities of land-use intensity of Guiyang,mainly,is triggered by several structural factors such as terrain and andform.Meanwhile,the effects of random factors of human activities should be included in this causation.
