摘要
利用重庆市北碚区2000—2012年的耕地面积和社会经济统计数据,分析其耕地资源的数量变化特征,采用主成分分析法定量分析了影响耕地面积变化的驱动因素,揭示了耕地面积变化的驱动机制。结果表明,北碚区耕地面积与人均耕地面积均呈现快速减少—缓慢减少的阶段变化特征;经济发展、农业发展因素、城市化水平和交通因素是影响北碚区耕地面积变化的四大主要驱动因子;可以从减少建设占用耕地、加强土地开发整理、加强高标准基本农田建设等方面达到保护耕地的目的。
Using the statistical data of arable land and social economy in Beibei district from 2000 to 2012, the article was to analyze the arable land quantity change features, to find out the driving factors using principal component analysis and to reveal the driving mechanism of arable land change. The results showed that the arable land declined from 2000 to 2012. Economic development, agricultural development factors, the level of urbanization and traffic factor were the four major driving factors of arable land area change in Beibei district.
