| 摘 要： | 以库布齐沙漠东部达拉特旗的农牧交错区为研究区域,以达拉特旗1987年、1995年、2000年和2003年四期遥感影像为信息源,在3S技术支持下,对遥感影像进行解译,获得1987—2003年来沙漠化动态变化数据,分析了该地区20世纪80年代中期到21世纪初的沙漠化变化情况,从土地流向角度探讨了沙漠化发展演变的动力机制。结果表明：该地区近20 a来,四个时期的沙漠化土地面积处于减少—增加—再增加的过程中,而沙漠化程度呈现减少—减少—增加的趋势,且2000—2003年间,是该地区沙漠化程度动态变化最大的时期。从土地流向看,各种土地类型向沙漠化土地之间的转化是导致沙漠化的一个重要原因之一,而土地利用类型之间的转化主要是由人类不合理的土地利用方式造成的。 |

| Abstract: | The study area is located in the east of Hobq Desert—Dalate County, in farming and pasturing interlocked area. Base on the \!3S\" techniques and combined with the ground review, the Land-sat TM images of year 1987, 1995, 2000 and 2003 were interpreted. This study analyzed the changes of sandland by using the database of desertification dynamics from 1987 to 2003. RS and GIS software, such as Erdas8.6, Arcview3.3 and ArcInfo7.1 were used as interpretation tools. The dynamic mechanism of desertification development was discussed from the aspect of land changing direction. The results showed that: the area of desertified land during the four periods was in the course of decrease-increase-increase, however, the desertification degree showed the trend of decrease-decrease-increase. Seeing from the aspect of land changing direction, the largest dynamic change of desertification degree appeared in the period of 2000—2003. The transformation of each land use type to desertified land was the important cause of desertification, moreover, the transformation among land use types were mainly caused by the unreasonable manner of anthropogenic land use. |
