Spatial Dynamic Variation and Driving Forces of Clultivated Land Use in Guangxi Zhuang Autonomous Region During the Past 30 year
摘要
Abstract
According to Guangxi Zhuang Autonomous Region 1978-2005 statistics,using the principal component analysis,the driving factors which influenced the cultivated land change in Guangxi Zhuang Autonomous Region were studied.
