摘　　要： 以贵州省盘县为主要研究区域,对Land Sat TM影像进行人机交互目视解译以及运用GIS的空间分析模块和空间统计模块,结果显示:(1)2007—2017年间研究区建设用地面积迅速扩大,耕地面积持续下降,灌丛面积有所增加,有林地和水域面积也有所下降;(2)土地利用类型的变化主要是耕地与建设用地和灌木林等生态用地之间的相互转移;(3)2007—2017年间,研究区土地利用变化强度很大,其中以建设用地和水域之间的利用动态度增幅最为明显,此外,研究区2007—2017年间的土地利用程度指数呈显著增长;(4)在喀斯特山区,坡度、高程对研究区土地利用格局的形成及演变有重要作用;(5)盘县矿区土地利用变化的主要驱动因子是人口增长和经济发展,同时还受到政府政策、城市规划以及人们环保意识提高的影响。总体上看,经济的大发展是矿区土地利用变化的主导因素。 Pan County in Guzhou Province as the mainly research area,an county in guizhou province as the main research area,interactive visual interpretation of Land Sat TM images,and the use of GIS spatial analysis and spatial statistics module,the results showed：（1） the study area from 2007 to 2017,the construction land area is expanding rapidly,cultivated land continues to decline,brush area increased,forestland and water area has also fallen;（2） the change of land use type is mainly the mutual transfer between cultivated land and land of construction and the ecological land such as shrubbery;（3）,2007-2017,change magnitude of land use in the study area is large,of which construction land and waters between the use of dynamic growth is most obvious,in addition,the study area during 2007-2017 of land use degree index were significantly increased;（4） in the karst mountains,slope and elevation play an important role in the formation and evolution of land use pattern in the research area;-（5） the main driving factors of land use change in the area of pan county are population growth and economic development,while also influenced by government policies,urban planning and people＇s awareness of environmental protection.Generally speaking,the major development of economy is the leading factor of land use change in mining area.
