中国耕地面积变化的驱动因子及模型研究

摘要

The characteristics of cultivated land change in China were analyzed according to the data of cultivated land change and other related data from 1996 to 2006. The driving factors of cultivated land change in China were studied quantitatively by the method of Factor Analysis and Stepwise Regression. The regression model of the driving factors and cultivated area was also established. Finally, related countermeasures and proposals were put forward.%采用1996~2006年的耕地面积变更数据和其他相关数据,分析了我国耕地面积变化的特征,运用因子分析法及逐步回归法,对引起我国耕地面积变化的驱动因子进行了定量研究,并构建了驱动因子与耕地数量的回归模型.最后,提出了相关对策建议.
