利用PCA-ESDA空间分析方法,测度了甘肃省县城农村空心化程度总体和局部空间差异格局.甘肃省农村空心化地域分异特征明显,呈现“西高东低,北高南低”的格局,高值区集中于河西走廊经济发达县域,低值区集中在黄土丘陵沟壑区和甘南高原等落后地区,在空间上体现出两极“俱乐部趋同”的集聚态势.按照各县土地、人口、经济子系统的交互特征,将甘肃划分为5个农村空心化区,并提出了分区调控对策.
Based on PCA -ESDA spatial analysis framework, the level of rural hollowing differ- ences in the overall and local spatial patterns were studied. Results illustrate that the spatial pattern of rural hollowing comprehensive level in Gansu is more advanced in north -western region than sourth - eastern region. There is prominence spatial difference between rural hollowing region development and the two - side club convergence exists in the rural hollowing in Gansu. The region around Hexi Corridor and region of Lanzhou, had becomethe high level club conver- gence, and the central, east and south region maybe in the" low - value club". The rural hollo- wing areas are divided into 5 regions in accordance with the interactive feature of land, population and economic subsystem. K
