数字高程模型在构造地貌形态分析中的应用现状及展望

构造地貌形态分析法是构造地貌学的基本方法之一，近年来随着数字高程模型（DEM）的发展，国内外对构造地貌形态分析的研究随之增多. 本文重点从基本地形因子研究、水系流域地貌、夷平面与古地貌面、构造活动评估、构造地貌分区、地貌发育模式及地貌参数计算工具开发等7个方面，总结了DEM在构造地貌形态分析中的研究应用现状和主要不足，以及存在的关键和难点问题. 总的来看，研究对象多集中在典型河流及流域、山前活动断裂带、板块交接构造活跃处、古地貌面；研究过程经历了从初期地貌形态的简单分析到多种地形参数的分析应用及其在地貌发
Structural morphology analysis method is one of the basic methods of tectonic geomorphology，the research on structural morphology analysis is developing with the development of the Digital Elevation Model（DEM）in recent years. Firstly，current researches and application of the DEM analysis to structural morphology were summarized and reviewed from seven points of view：basic terrain factor research，drainage basin landform，planation surface or paleo-surface reconstruction，tectonic activity evaluation，partition of tectonic geomorphology，landscape development model，and geomorphic parameter calculation tools. The key and difficult problems are also introduced. Then this paper summarized that the object of these studies are focused on the typical rivers or river basins，piedmont fault zone，tectonic activity plate，paleo-surface；Research process has experienced the change from the initial simple analysis to the application of terrain parameters of morphology analysis and with the application in landscape development；The research scale is from hundreds of square kilometers of the small watershed to thousands of square kilometers of the landscape. But the application of geomorphic index in inland areas，the method of tectonic activity hierarchy，multi-level and multi-angle geomorphic research still need to improve and further develop. Lastly，the view of the existing problems，and the digital elevation model in the application of the structural morphology analysis in future is prospected
