摘　　要：自2000年以来,赣南中央苏区的土地利用发生了较大变化。以赣南中央苏区2001、2009、2017年的遥感影像为数据源,应用遥感和GIS软件提取3期土地分类数据,揭示其土地利用动态度、转移情况,并分析土地利用变化的人文驱动因素。结果表明:研究区的主要土地利用类型为林地和草地,两者占总面积的75%以上;草地先增后减,耕地和水体先减后增,林地和其他用地持续减少;建设用地则先缓增,后快速增长,共增加475.99km2。研究前期,建设用地的增加主要是占用大量耕地,后期主要向地沿河湖低洼地段扩张,占用大量草地和水体,耕地面积则有所回升。人口、经济和政策是土地利用变化的主要驱动因素。Great changes have taken place in the land use of the Central Soviet Area in southern Jiangxi Province since 2000.Based on the remote sensing images of the Central Soviet Area in southern Jiangxi Province in 2001,2009 and 2017,this paper used RS and GIS software to extract three periods of land classification data,and then re⁃vealed the dynamic degree and transfer of land use,and finally analyzed the human driving factors of land use change.The results showed that:The main land use types of the study area were woodland and grassland,which ac⁃counted for more than 75%of the total area;Grassland increased first and then decreased,cultivated land and water decreased first and then increased;Woodland and other land continued to decrease;Construction land increased slowly and then rapidly,with a total increase of 475.99%;In the early stage of the study,the increase of construction land was mainly due to the occupation of a large number of cultivated land,and in the later stage,due to the occupa⁃tion of a large number of grassland and water,it mainly expanded to the low-lying areas along the rivers and lakes,and the cultivated land area rebounded.Population,economy and policy are the main driving factors of land use change in the Central Soviet Area of Southern Jiangxi Province.
