| 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。

| Abstract: | Using GeoDA,ARCGIS 9.2,taking the Cheng Kun railway as the radiation axis,to study 2008 GDP of average per capita as indexes of the county-level administrative unit as the object within 50km of the railway.The economic spatial 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... |
