摘要 以山西省吕梁市离石区作为研究对象，选择2008—2017年五幅遥感影像图，使用ENVI、ArcGIS软件，对影像进行预处理以及监督分类，获取离石区5年的土地利用分类信息。通过土地利用变化转移矩阵、线性分析等方法对影响离石区土地利用变化的人文因素和自然因素2个方面进行分析。结果表明，离石区最主要的土地类型为耕地和林地，2008—2017年林地面积减少了46.59 km2，耕地面积减少了53.17 km2，裸地面积增加了14.77 km2，建筑用地面积增加了92.19 km2，河流面积减少了7.21 km2。在这期间，耕地、林地、裸地主要转化为建筑用地，耕地与林地之间也存在相互转换关系。从驱动力因素来看，离石区GDP、人口、第一产业产值、第二产业产值、第三产业产值对土地利用变化均有相关关系，离石区的地质地貌也对土地变化有所影响。

Abstract This paper selected Lishi District of Lüliang City，Shanxi Province as the research object， and selected five remote sensing image maps from 2008 to 2017，and ENVI and ArcGIS software were used to preprocess and supervise the images to obtain land use classification information in Lishi District for 5 years.Through land use change transfer matrix， linear analysis and other methods， the two aspects of human factors and natural factors that affected land use changes in Lishi District were analyzed.The result showed that the most important types of land in the off-stone areas were arable land and woodland. During 2008-2017， the area of forest land decreased by 46.59 km2， the area of cultivated land decreased by 53.17 km2， the area of bare land increased by 14.77 km2， the area of construction land increased by 92.19 km2， and the river area decreased by 7.21 km2.During this period， cultivated land， woodland and bare land were mainly converted into construction land， and there was also a mutual conversion relationship between cultivated land and woodland. From the perspective of driving factors， Lishi Districts GDP， population， output value of the primary industry， output value of the secondary industry and output value of the tertiary industry were all related to land use changes， and the geology and landforms of Lishi District also affected land changes.

土地利用變化是全球环境变化与可持续发展研究的重要内容。土地资源是人类社会赖以生存和发展的物质基础，作为一种重要的基础性资源，其利用变化不仅影响着社会经济的发展，同时也对生态环境有着深刻的影响，尤其是生物多样性和生态系统的服务功能。21世纪以来，随着全球化的进程不断加深，在可持续发展战略的主题下，如何更加合理地利用土地资源，充分发挥土地资源优势已经成为全球研究的热点[1]。土地变化可以直观地呈现自然条件的变化和人类活动的程度，深入了解土地利用变化及驱动力因素不仅为揭示全球生态系统提供依据，更为改善区域环境及合理配置土地资源提供理论支持和实践指导。……
