中文摘要	处于我国西北内陆干旱荒漠地带的世界最高大的沙丘系统--巴丹吉林沙漠横向沙山系统,具有重要的风沙地貌与沙漠第四纪地质及水文学研究价值.以往的研究主要取得了对该沙漠及其沙山的近130 ka来环境变化历史的框架性认识.沙漠的形成时代、沙源、沙山及其间湖泊的成因与演化过程等及其与区域及全球气候环境变化的关系需要进一步研究.在研究方法上,需要重视沉积学方法的应用.对这些问题的深入研究,不仅对认识其自身奥秘,促进风沙地貌学与沙漠第四纪地质学的进展,而且对认识区域气候、环流、水循环、大地构造等重大环境问题具有重要作用.
英文摘要	The Badain Jaran Desert transverse mega-dune system in inland arid desert zone of northwestern China, as the highest dune-system in the world, has significant research value in the aspects of Aeolian Sand Geomorphology and Quaternary Geology and Hydrology. The acquired research achievements are mainly a-bout the general environmental change history of the desert and its mega-dunes during the latest 130 ka. There are still some important problems waiting for further studying, they are the desert formation age and sand source, the causes and evolution of mega-dunes and inter-dune lakes, and the relation between regional and global climate environment changes, etc. The sedimentology method should be firstly applied. The solution of these problems can not only open up its mystery, but also has great significance on knowing the great environmental problems such as regional climate, air circumfluence, water cycle, geotectonics, etc, thereby to promote the development of aeolian sand geomorphology and Quaternary geology about desert.
