| 摘 要： | 基于武汉市1997~2006年的统计数据,从耕地资源变化的时间特征和空间差异入手,分析了武汉市耕地资源变化的规律与趋势,并运用因子分析和多元线性回归相结合的方法,定量分析了该市耕地资源变化的驱动因素。结果表明,武汉市耕地资源变化的时空特征明显,耕地资源呈现出减少的总体趋势;人口增长、经济发展和农业科技进步是影响武汉市耕地资源数量变化的3类因素。研究结论对武汉市合理利用耕地资源,实现地区农业的可持续发展具有重要意义。

| Abstract: | According to the statistical data from 1997 to 2006,the trend and law of arable land change,especially for the temporal and the spatial difference,were analyzed.As a result of the factor analysis and multiple linear regression,the main driving force of arable land change were discussed.The results showed that the spatial-temporal features of arable land change in Wuhan were notable,and the arable land decreased year by year.The population growth,economic development and progress of science and technology in agriculture were the three factors which affected the arable land change in Wuhan city.The analytical conclusions would help people make good use of arable land resources and provide scientific basic for sustainable agriculture development in Wuhan city. |
