摘　　要：应用GIS技术和空间自相关分析方法,分析了2002～2010年广西县域人均耕地的空间变化特征。结果表明:广西县域人均耕地差异存在较大的波动,县域人均耕地差异与空间集聚同步发展和反向发展存在于广西县域人均耕地变化的不同时期。在广西时空格局演变中,存在县域人均耕地差异的空间格局变化频繁呈现点块状分布、出现热点组团区域两大特点。Using GIS and spatial autocorrelation analytical method,characteristics of spatial distribution evolution of per capita arable land in counties of Guangxi province from 2002 to 2010 were analyzed.The results indicated that there is a larger fluctuation among the per capita arable land＇s differences in Guangxi counties;per capita arable land＇s differences in counties and synchronous development and backward development of spatial agglomeration existed in the different changing periods of per capita arable land in Guangxi counties.During spatial distribution evolution in Guangxi province,there is spatial distribution of per capita arable land＇s differences in counties changed frequently and presented two characteristics,one is point-block distribution,the another is appearing hot group area.
