基于Landsat卫星遥感数据，运用GIS方法，对额济纳旗1986-2000年以土地利用类型为表征的时空变化特征进行了研究。结果表明：14年来该区草地、林地、水域、耕地面积减少，居民工矿建设用地和未利用土地面积显著增加，土地利用动态转化过程以草地转化为未利用土地、林地转化为草地和未利用土地逆转为草地为主要特征，全旗土地利用的空间位置转换面积大于其数量变化。而气候变化和人类活动是导致研究区土地利用变化的主要因素。

Based on Landsat remote sensing data and using GIS method, this paper studies the spatial distribution pattem variations of land use in Ejina region from 1986 to 2000, with the result that the areas of grassland,forestland,water bodies and cultivated land were decreased in those 14 years, while the areas of residential and industrial lands and the unused lands were remarkably increased. The dynamic land use changes were mainly characterized by the transformation of grassland and forestland into unused land and grassland respectively, and the conversion of the unused land to grassland. The spatial transformation area of land use was lager than the amount of changes all over the region, with climate changes and human activities as the main causes of land use changes in the region.
