| 摘 要： | 利用PCA-ESDA空间分析方法,测度了甘肃省县域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。

| Abstract: | Based on PCA-ESDA spatial analysis framework,the level of rural hollowing differences 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 become the high level club convergence,and the central,east and south region maybe in the"low-value club". The rural hollowing areas are divided into 5 regions in accordance with the interactive feature of land,population and economic subsystem. |
