摘要
根据2004—2011年内蒙古自治区统计年鉴的相关数据,研究内蒙古耕地面积的时空变化情况,通过Arcgis软件分析其空间变化的分布格局特征,运用SPSS软件主成分分析法探寻影响其变化的主要驱动因子。
The spatial- temporal change of arable land area in Inner Mongolia Autonomous Region is investigated based on the modification data from 2004 to 2011. The results show that the total area and per capita area of arable land had been declining. With the method of principal component analysis,driving forces of farmland quantity change were analyzed increasing with population,the development of economy,the advancement of technology.
