摘要
巴丹吉林沙漠南缘地区含风成砂地层广泛分布。由于受东亚夏季风降水尾闾摆动的影响，本区沙漠在晚更新世以来的演化中表现出微弱的波动性质。全球冰期气候波动主宰着本区沙漠的演化方向；青藏高原的隆起使该区变得更加干旱。
Badain Jaran desert,lying in the transitional region between Western China’s deserts andEastern China’s deserts, has undergone a series of changes from the occurrence of shifting sand,extension, fixation to decline since late Pleistocene, The analytical results of eolian sand stratademonstrate that the East Asian summer monsoon bought in relatively plentiful rainfall to this area inthe interglacial periods, on the other hand, this area was very dry in the glacial periods. The uplift of Qinghai-Xizang Plateau reduces humidity and makes the temperature lower in the area.
