摘　　要：为研究靖远县县域发展和土地利用情况,选取2000、2005、2010、2015、2020年Landsat遥感图像数据和统计年鉴数据,利用土地利用动态度和土地利用转移矩阵分析土地利用结构的变化,采用主成分分析研究主要驱动因素。结果表明,整体上建设用地的单一土地利用动态度最大且变化程度最剧烈,林地土地利用动态度均为正值。未利用地、耕地和建设用地面积增加,林地和水域面积变化不大,草地面积减少。靖远县20年间未利用地面积增加最为明显,其次是建设用地和耕地,草地面积减少较多。靖远县土地利用变化的主要驱动因素与人民生活水平、农业和经济发展水平有很大关系。In order to study the county development and land use of Jingyuan County,Landsat remote sensing image data and statistical yearbook data in 2000,2005,2010,2015 and 2020 were selected to analyze changes of land use structure by land use dynamic degree and land use transfer matrix,and the main driving factors were studied by principal component analysis.The results showed that overall,the single land use dynamic degree of construction land was the largest and the degree of change was the most severe,and the land use dynamic degree of forest land was all positive.The area of unused land,cultivated land and construction land increased,the area of forest land and water area changed little,and the area of grassland decreased.In the past 20 years in Jingyuan County,the unused land area increased most significantly,followed by the construction land and cultivated land.The grassland area decreased more.The main driving factors of land use change in Jingyuan County were closely related to people’s living standards,agricultural and economic development levels.
