摘　　要：近年来,青藏高原一直是国际及国内地质学界极其关注的地区。随着遥感技术的发展,基于DEM的地表过程分析给青藏高原研究带来了崭新的思路和方法。本文回顾了应用DEM数据进行青藏高原地貌研究的历史,通过分析其应用研究的几个阶段,总结了DEM技术在高原上的研究技术,阐述了DEM数据在各学科中的交叉应用,指出研究方法上的系统化、信息的进一步挖掘和高精度数据源获取是该领域发展的主要任务,并展望了DEM在地貌研究中的发展方向。In recent years, many researchers have been involved in the study of Tibet plateau. The development of the remote sensing technology and more and more sophisticated DEM -based analytical methods has provided researchers with a new means for studying Tibet plateau. This paper has briefly reviewed the history of applying DEM data to the study of Tibet plateau. Based on studying several stages in using DEM data, the authors analyzed the methods for data fusion of multi - sensor and the application of DEM data in many fields. It is pointed out that the systematization of the research method, the deep extraction of information and the acquiring of high - precise data seem to be the main tasks in future researches of this field. The problems that should be solved in future are also discussed.
