摘　　要： 广州市1980—2002年间产业发展可分为两个阶段,即工业化中期(1980—1993年)和工业化后期(1994—2002年)。在这两个产业发展阶段,耕地数量变化存在较大差异。耕地年均减少工业化中期大于后期,变化速度则是后期大于中期,利用效益后期明显优于中期。利用相关分析和主成分分析方法,得出人口增长、经济发展、城市化进程、农业产业结构调整、交通发展是广州市1980—2002年间耕地数量变化的主要驱动力,在不同产业阶段各驱动因子存在差异,其中农业比重、实际利用外资、城市化、客运量等因子差异较为明显,从而导致了不同时期耕地数量变化的差异性。 This paper divided the industrial development into 2 phases from 1980 to 2002 in Guangzhou City,i.e. metaphase of industrialization （ 1980-1993 ） and anaphase of industrialization （ 1994-2002 ） .And in the two phases, differences were on the quantitative change of cultivated land,which metaphase were more than anaphase in decrement of per year,less than anaphase in change rate, and anaphase excelling metaphase in invert benefit. Based on relevance analysis and principal component analysis, it could be concluded that main driving forces from 1980 to 2002 on cultivated land change were population growth, economic development,urhanization,adjustment of agricultural industry structure, development of traffic. Furthermore, their effects on cultivated land were diverse to some degree in different industrial phases,and some have obvious differences, including proportion of agriculture, factual utilize of foreign capital, urbanization, passenger traffic. And these differences resulted in the differences of cultivated land change.
