| 摘 要： | 根据1994～2004年定西市耕地统计资料,运用主成分分析法对该市耕地资源利用与变化的基本特征和主要驱动机制进行了分析,将其概括为人口、经济和土地生产力三种类型,同时对耕地面积变化及其影响因子的关系进行了定量研究。在此基础上,建立了耕地动态变化与社会驱动因子综合指数之间的线性回归模型。

| Abstract: | This paper making use of the statistical data of cultivated land from 1994 to 2004 in Dingxi city, studies the basic features and driving forces about utilization and change of the cultivated land. Then a quantity study made on the eight chosen driving forces factors which affect change of cultivated land by using Principal Component Analysis. The result can be generalized as the population factor, economic factor and that of land productivity force. A linear regression model is made in the end. |
