摘要
以1996～2006年期间我国耕地面积数量变化为基础,分析了耕地面积变化的区域差异;以GDP、人口、第一产业增加值、固定资产投资为关联因子,对影响耕地面积变化的经济社会因子进行了灰色关联分析及多元线性回归分析。结果显示:虽然耕地面积普遍减少,但我国区域耕地面积变化的引致因子差异显著,耕地利用与保护政策需要讲究区域性策略。
The paper makes an analysis on regional differences of amble land area change based upon the number of China's cultivat- ed acreage changes during 1996 to 2006.It also gives a grey corre- lation and multiple linear regression analysis on social-economic factors which influence the change of arable land area in accordance with some related factors,such as GDP,population,the first in- dustrial added value,fixed asset investment.The results showed that:although the cultivated land area generally decreased,the fac- tors that caused the changes of regional arable land area have re- markable differences;so in terms of land use and protection poli- cies we need to pay attention to regional strategy.
