摘　　要：以大理州作为研究区,选择2000年、2010年、2020年三期的土地利用数据,基于GIS空间分析、土地利用转移矩阵、单一土地利用动态度等理论方法,对其土地利用变化及其驱动力进行研究。结果表明:大理州近20年土地利用变化以耕地、林地、草地和不透水表面变化为主,不透水表面面积持续上升,草地面积持续减少,耕地和林地间保持动态平衡,草地主要转变为了耕地和林地,不透水表面主要由耕地和草地转入;大理州近20年土地利用发生变化的主要驱动力因素是大理州经济结构的调整和国家洱海保护政策的实施。Taking Dali Prefecture as the research area,land use data from three periods of 2000,2010,and 2020 were selected.Based on theoretical methods such as GIS spatial analysis,land use transfer matrix,and single land use dynamic degree,the land use change and its driving forces were studied.The results show that in the past 20 years,the land use change in Dali Prefecture has been mainly characterized by changes in arable land,forest land,grassland,and impermeable surfaces.The impermeable surface area has continued to increase,while the grassland area has continued to decrease.The dynamic balance between arable land and forest land has been maintained,and grassland has mainly transformed into arable land and forest land,while impermeable surfaces have mainly shifted from arable land and grassland.The main driving factors behind the changes in land use in Dali Prefecture in the past 20 years are the adjustment of its economic structure and the implementation of the national Erhai Lake protection policy.
