摘要
文章首先概述独龙江流域的地貌基本形态结构，分析现代地貌作用的外营力，讨论地质构造和地表物质对研究区地貌形成的作用和影响。作者着重根据现代冰川分布及其特征、古冰川遗迹、冰缘地貌类型和古冰缘地貌遗迹，研究独龙江流域全新世以来的构造抬升和气候演变。最后分析研究区坡地形成过程，河流地貌的发展与演变，阐述独龙江流域的地貌发育史。总之，文章坚持将今及古的观点。
The paper outlined the basic structure of landforms, analysed the external agencies which acted on the modern landforms, and discussed the geologic structure and the surface material which affected the Iandforms in the Drung river basin. The author studied the tectonic lifts and the climate changes since Quarternary, according to the distribution and the characteristics of the modern glaciers and the ancient, the types of frozen ground and the left gelisol. The author analysed the dynamic process of the slopes, studied the development and the evolution of the streams, described the developing history of the lanforms in the end. At last, the paper sticked to the viewpoint of'Now is the key of knowing past',opposed that glaciers happened everywhere and tectonic movements existed everywhere.
