摘要:
以库布齐沙漠东北部的农牧交错区为研究区，采用1987年、1995年和2000年的TM影像为数据源，在3S技术支持下分析了各时期沙丘面积、沙漠化程度及1987-1995年、1995-2003年两个时间段内的土地类型转移矩阵。结果表明：研究区沙漠化土地面积呈减少趋势，从1987年的105 582.2 hm2减少到2003年的83 326.7 hm2，沙漠化程度由0.407降为0.259，各类沙丘主要是与耕地、草甸和林地之间存在转换，农业生产活动是库布齐沙漠地区的沙漠化主要驱动因素。
Abstract:
This study area is located in the northeast of Hobq Desert, in farming-pastoral ecotone. The Land-sat TM images of 1987, 1995 and 2003 were interpreted based on 3S software (ArcView 3.2, Erdas 8.6 and ArcGIS 9.0). This paper analyzed the desertification dynamics by comparing desertified area and degree of desertification in 1987, 1995 and 2003. And the progresses of the land use change was analyzed by using convection matrixes from 1987 to 1995 and 1995 to 2003. The results show that: the area of desertified land decreased from 105 582.2 hm2 in 1987 to 83 326.7 hm2 in 2003. Meantime, changing trend of desertification degree decreased from 0.407 to 0.259 during this period. Desertified land mainly transferred to cropland, meadow and woodland. The main drive force of desertification change was agricultural activities.
