| 摘 要： | 利用德江县1990~2005年间的耕地序列数据以及相关社会经济资料,分析了德江县耕地资源的时空动态变化规律。同时建立指标体系,利用SPSS对耕地面积动态变化的驱动因子进行主成分分析,揭示耕地变化的驱动机制。研究表明,社会经济发展、农业科技进步、基础建设和人口压力是造成德江县耕地资源持续减少的主要动因。最后进一步分析了这些驱动因子与耕地变化的关系。

| Abstract: | The spatial-time dynamic change rule of cultivated land and social economy material were analyzed through data of Dejiang from 1990-2005.The index system was established and the principal component of the driving factor of dynamic changes mechanism was analyzed with SPSS.The result indicated that the social economy development,the agriculture technical advanc,the infrastructure and the population pressure constituted the main driving factors resulting in the continual reduction of cultivated land resource in Dejiang.And finally,the relationship among these driving factors and the cultivated land was analyzed. |
