摘　　要：以成昆铁路为辐射轴,以50km为辐射半径所形成的辐射范围内的县级行政单元为研究对象,以2008年人均GDP为研究指标,运用GeoDA和ARCGIS 9.2对成昆铁路辐射带经济空间差异进行分析。从全局相关分析来看,研究区域各县级行政区人均GDP水平存在着显著的、正的空间自相关性,空间分布表现为相似值之间的空间集聚。通过LI-SA空间聚集性分析,经济发展水平较高的县域主要集中在四川的成都及其周围县域,经济落后的地区集中在四川阿坝和云南楚雄州,表明区域经济发展存在极化现象。在此基础上分析了影响经济空间分异的主要原因,提出了对策。Using GeoDA, ARCGIS 9.2, taking the Cheng Kun railway as the radi- ation axis, to study 2008 GDP of average per capita as indexes of the county - lev- el administrative unit as the object within 50kin of the railway. The economic spa- tial differences were found： analysis from the global correlation analysis, research area is the county administrative region level of GDP of average per capita has a significant, positive spatial autocorrelation, spatial distribution showed similarity values between the spatial agglomeration. According to the LISA analysis of spatial concentration, higher level of economic development of the county are mainly con- centrated in the Siehuan Chengdu, around the county, economy is backward area in Sichuan ABa, Yunnan Chuxiong. It indicates that regional economic develop- ment exists polarization phenomenon. On the basis, analyzed of the main reason for economic spatial difference,offered countermeasure.
