| 摘 要： | 本研究依据1997—2006年甘南州统计资料,运用因子分析方法和回归分析法,分析了甘南州耕地面积变化的总体趋势、空间差异和驱动因子。结果表明,甘南州耕地总体呈逐年减少态势,且空间差异显著;固定资产投资、农业总产值、农民人均纯收入和城镇化水平是影响甘南州耕地面积变化的四大因素,退耕还林(草)政策是耕地减少的阶段性因素。通过建立耕地面积与驱动因子的多元回归模型,预测出2007—2020年的甘南州耕地数量。

| Abstract: | Based on statistical data in Gannan prefecture from 1997 to 2006,the generally changeable trend of arable land area,spatial difference and driving factors causing changes in arable land area were investigated by using factor analysis and regression in this study.This study indicated that the total area of arable land was in a reduction trend,and this reduction was significantly different among spatial distribution.Fixed assets,total agricultural output,rural per capita net income and urbanization level were... |
