数字高程模型(DEM)在构造地貌研究中的应用新进展

Recent progress in the DEM-based tectonogeomorphic study

简要介绍了数字高程模型(DEM)的基本概念,系统总结了近些年来DEM空间分析技术在构造地貌研究中的最新进展,列举并讨论了DEM相关数据和技术在典型地貌特征分析和宏观构造地貌演化研究中的典型应用实例。数字高程模型(DEM)理论和数据精度的不断发展和提高,DEM及其空间分析技术与相关地学研究手段相结合的复合分析,必将为构造地貌研究实现定量化提供强有力的技术支持。

This paper briefly introduces the basic concept of the digital elevation model （DEM）, summarizes the recent progress in the DEM application in the study of tectonogeomorphic features and enumerates and discusses some case histories of applications of relevant DEM data and techniques in the analysis of typical geomorphic features and study of macro- tectonogeomorphic evolution. With the continuous development of the DEM theory and data precision, the integration of the DEM and its space analytic technique with the relevant approach to geoscience research is bound to provide a strong technical support to the quantification of the tectonogeomorphic study.
