摘　　要：由于城市的快速发展,城市土地利用变化越来越引起重视。以武汉市为研究区,基于RS和GIS技术手段,分析了1991~2005年武汉市土地利用变化幅度与单项土地利用类动态变化,在此基础上,分析了武汉市土地利用变化的驱动力。研究结果表明：（1）武汉市在1991年至2005年间,土地利用类型发生了较大的变化。主要表现在武汉市的农用地和未利用地的面积大幅度减少,建设用地的面积迅速增加,水体和绿地的面积变化保持稳定。（2）经济增长是影响武汉市土地利用变化的最主要因子,其次为人口增长因素。The urban land use change was much accounted of scholars due to the rapid development of the city. Land use change amplitudes and land dynamic change rates were studied in Wuhan city from 1991 -2005 based on RS and GIS. On that basis, it analyzed the land use change driving force in Wuhan city. The study results showed： （1）Land use types had major changes from 1991 -2005. It is mainly manifested that the farmland and unused land area were greatly reduced,construction land area increased rapidly, river water and green land area remained stable; （2）Economic growth was the most main factors that affected the change of land use, the followed factors was population growth in Wuhan city.
