摘要:依据武汉市2000—2009年耕地面积和社会经济统计数据,分析了该市耕地数量变化的过程,并运用主成分分析法分析了该市耕地数量变化的驱动因素。研究表明:耕地总面积在时间上分为3个不同的变化时段,空间位置上表现出区域差异,人均耕地面积呈现逐年下降趋势。近年来人口增长、经济发展和农业科技进步是武汉市耕地资源数量变化的主要驱动因素。研究结论对武汉市保证耕地总量动态平衡,实现耕地资源的可持续利用具有重要意义。

Abstract: According to the cultivated land area and social-economic statistical data in Wuhan during 2000—2009,the driving forces of the cultivated land area changes were analyzed by means of principal component analysis. The research indicated that the total area of cultivated land in the time period was divided into three different variations and showed regional differences in spatial position while per captia of cultivated land appeared declining year by year. Population growth, economic development and agricultural scientific and technological progress have been the main driving factors of changes in the amount of cultivated land resources in Wuhan. The research conclusions would be important to ensure the dynamic balance and achieve the sustainable use of cultivated land resources in Wuhan.
