摘要
在GIS技术支持下,以甘肃省1997--2006年土地利用变更调查数据及相关经济社会统计数据为基础,借助系统论中的信息熵原理,揭示了甘肃省用地结构动态演变特征,阐述了影响土地利用结构动态演变的主要自然、政策等驱动力,最后利用主成分分析方法,对该区用地结构动态演变的经济社会主要驱动因子进行了分析与探讨。
Under the support of GIS, based on the data of land use change survey from 1997 to 2006 in Gansu province and the associated economic and social statistics, the characteristics of dynamic evolution of land use structure in Gansu province were expounded utilizing the information entropy principle of systematic theol. Furthermore, the driving forces to influence the main characteristics in terms of natural and policy factors were explored. Finally, in virtue of analytical methods on the principal component, the main economic and social driving factors were analyzed and discussed for dynamic evolution of land use structure in the region.
