摘　　要：在Landsat TM和ASTER GDEM数据分析基础上,结合GPS定位,对库布齐沙漠风沙地貌类型、形态特征进行定量分析。结果表明,库布齐沙漠风沙地貌类型有新月形沙丘及沙丘链、灌丛沙丘、格状沙丘、复合型沙丘、抛物线形沙丘、平沙地等;各类风沙地貌的分布与地形因子具有一定相关性;各类风沙地貌分维值变化不大,表明其处于相对稳定的演化过程中。研究为库布齐沙漠综合治理提供基础资料。Based on the Landsat TM and ASTER GDEM data analysis and combined with the GPS field research, the distribution range of the Hobq desert and the type, distribution, morphological characteristics of sand physiognomy were quantificationally analyzed. The results showed that, the types of sand-physiognomy included meniscus dune, shrub dune, trellis dune,complex dune, parabolic dune, and flat dune. The distribution and the terrain factors of all kinds of sand physiognomy had a certain correlation. The fractal dimension value changed little, indicating sand physiognomy was in a relatively stable evolution. The research provided basic information to the comprehensive treatment of the Hobq desert.
