Abstract: Based on the principles of taking sand dune type as dominant accordance and relatively concentrating as the second, the aeolian landform configurations in northern Badain Jaran Desert are divided into 3 regions and 8 sub regions from the northwest to the southeast: Ⅰ.longitudinal sand ridge region, including fixed and semi fixed longitudinal sand ridge sub region; longitudinal sand ridge sub region; and longitudinal sand ridge to star dune sub region. Ⅱ.Barchan dune and chain region, including barchan dune and chain sub region; barchan dune and chain to star dune sub region; barchan dune and chain to scaled dune sub region. Ⅲ.Star dune region, including star dune and compound megadune sub region; star dune sub region. In fact, the spatial features of landform assemblage in the studied area have shown the regularity of dune formation and evolution. The dunes in the southeast are older than those in the northwest.
