【摘要】 根据1997～2005年的耕地统计数据及相关的社会经济资料,分析了闽东南地区耕地资源动态变化趋势;利用SPSS软件对9个驱动因子进行主成分分析,揭示研究区耕地利用变化的驱动机制。结果表明:近10年来,闽东南地区的耕地数量总体上呈减少趋势;社会经济发展、人口增长压力、比较经济利益驱动和城市建设是研究区耕地减少的4个驱动因子,并进一步分析了这些驱动因子与耕地变化的关系。其结果将为进一步研究闽东南地区耕地变化提供借鉴,为合理利用和保护耕地、促进区域可持续发展提供科学依据。更多还原

【Abstract】 According to the statistical and survey data from 1997 to 2005,the overall tendency of cultivated land resource changes in Southeastern Fujian were discussed in this paper.With the method of principal component analysis by SPSS,the 9 driving forces of cultivated land change were analyzed and its motive mechanism was revealed.The results showed that in recent 10 years,there was a general trend of decrease in cultivated land resource.Economical development,the pressure of population growth,compared economic benefits and the urban construction were the mainly driving forces factors for change of cultivated land.Based that,the relations between the driving forces factors and the cultivated land change were analyzed.The analytical results and conclusions will be beneficial to providing theoretical and practical guide for the variation and protection of cultivated land,and scientific basis for sustainable development.更多还原
