| 摘 要： | 基于ESDA全局和局部空间自相关分析,利用甘肃省1992～2006年县域人均GDP数据,对甘肃省县域总体和局部空间差异的变化趋势、特征与成因进行了初步探索。结果表明:甘肃省经济空间自相关特性明显,经济发展水平相似的地区在空间上集聚分布,呈现出"哑铃"形的空间格局,即经济发达地区集中分布在河西地区,经济发展水平较低的地区集中分布在陇中、陇南、陇东地区。

| Abstract: | Based on the global and local spatial autocorrelation analyses of Exploratory Spatial Data Analysis(ESDA),this research investigated the spatial dynamics of regional disparities at the county level in Gansu by analyzing GDP per capita,1992-2006.Results showed that spatial autocorrelation of Gansu Province at the county level is significant.That is,the relatively high(low) developed county tends to be located nearby other high(low) counties more often than expected due to random chance.The relatively high de... |
