基于GIS和遥感的土地利用演变及驱动力分析——以汾河上游西北地区为例

摘要

As land is the basis for human survival, rational use of land is fundamental to sustainable development; Land use patterns and intensity determine whether human could use earth resources in a long-term and in a sustainable way. Through combining unsupervised and visual interpretation methods and using land satellite data under the support of CIS and RS technology, in this paper thematic information from remote sensing images of three periods (1976, 1990 and 2007 years) was extracted. Then dynamic degree of land use was established, and the evolving tendency of this place and its driving forces were analyzed according to statistical data.%土地是人类生存的基础,合理利用土地是可持续发展的根本.而土地利用方式和强度决定了人类能否长期、可持续地利用地球资源.在GIS和RS技术支持下,利用陆地卫星遥感数据,通过非监督分类与目视解译相结合的方法,提取1976,1990,2007年3期遥感影像专题信息,建立了土地利用变化模型,并结合统计资料完成了汾河上游西北地区土地利用演变趋势及其驱动力的分析.
