Base on comparison with the remote sensing data in 1982 and 2000 and field investigation, the results of land cover and land use change were obtained by the method of landscape analysis. Ten types of land use were identified: riparian woods, riparian shrubbery, desert shrubbery, desert grassland, river-way and water area, salinised land, town, Gobi, shift sand dune, denudative upland. The results show that,(1) there were obvious changes in land cover structure.

根据黑河下游额济纳绿洲土地生态分类，利用1982年与2000年2期TM遥感数据对比和野外实地调查，采用景观生态空间分布格局分析方法，分为河岸乔木林、河岸灌草林、荒漠稀疏灌丛、荒漠稀疏草地、河道与水域、盐碱化土地、城镇、戈壁、流动沙丘和剥蚀地山丘陵，从各类土地分布面积变化和类型转移趋向与幅度两个方面，分析了额济纳绿洲20年来土地覆被变化。

With the ETM+ as data source,the Dimidiate pixel model was established based on vegetation index to extract vegetation coverage in Maowusu sandland.

以ETM+为数据源，基于植被指数建立像元二分模型，对毛乌素沙地进行了植被覆盖度提取，然后根据实地调查数据对提取结果进行了精度验证，二者线性相关系数达到了0.92，平均精度为79.4%。

The investigation results show that the shrubs diameter apart from root 50 mm mostly shall not exceed 15mm, such as Caragana Korshinskii Kom, Vitex, Fourfold Acacia, and Grewia biloba var.parviflora. The moisture content of the above shrubs is about 55%, 55%, 61% and 50% separately in late autumn and winter when they are reaped.
