摘　　要：以阿拉善盟2000年TM卫星影像遥感信息为主要依据,根据中国北方土地沙漠化动态分类系统,在遥感影像上进行解译和面积量算,获得了阿拉善盟2000年土地沙漠化状况:沙漠化土地总面积3666232.9hm2,占土地总面积的15.48%。阿拉善盟主要的沙漠化类型为沙丘活化或流沙入侵(1846880hm2)、灌丛(草地)沙漠化(735369.5hm2)、砾质沙漠化(1064944hm2)和耕地沙漠化(19039hm2)。沙丘活化或流沙入侵主要分布在阿拉善左旗境内,巴丹吉林沙漠与腾格里沙漠和乌兰布和沙漠之间的一些低山丘陵和荒漠干草原上;灌丛(草地)沙漠化主要分布在阿拉善东部;砾质沙漠化主要分布在阿拉善盟的西部,尤其以额济纳旗最多;耕地沙漠化主要集中在额济纳绿洲。Based on 2000 TM data of Alashan League in 2000 and classification system of desertification lands in North China, the area of desertification lands was calculated. The results showed that there were 3666232.9hm^2 desertification lands in Alashan League in 2000, accounting to 15.48% of total land area there. The main types of desertification lands in Alashan League are dune activation and shifting sand invading （1846880hm^2）, shrub （grassland） desertification （735369.5hm^2 ）, gravel desertification （ 1064944hm^2 ）, and farmland desertification （19039hm^2）. The dune activation and shifting sand invading type is mainly distributed on low hills and deserted dry grassland between Badain Jaran Desert and Tenger Desert; shrub （grassland） desertification is mainly distributed in eastern of Alashan League; Gravel desertification is mainly distributed western Alasha, especially in Ejina Banner; Farmland desertification types is mainly concentrated in Ejina Oasis.
