摘要
本文概述了横断山区地貌区划的基本原则和划区依据。在分析本区地貌特征的基础上,将区内地貌划分为2个地貌区;Ⅰ.横断极大起伏大起伏高山山原地貌区;Ⅱ.云贵川高中山山原地貌区,13个地貌地区,并分别论述了各区主要地貌特征。
Geomorphologic regionalization of the Hengduan Mountainous Region should be by the pri-nciple of morphogenetic mainly being landforms.According to amplitude of the uplift of the neotectonic movement, elevation and the assemblage difference of exogenetic forces, landforms in the Hengduan Mountainous Region may be divided into 2-geomotphologic regions, i.e., I. Hengduan high mountain and mountain plateau region with high and extremely high relief, I . Yunnan-Guizhou-Sichuan high-middle mountain and mountain plateau region.Based on landform subassemblage formed by endogenetic and exogenetic forces, intact degree of planation surfaces, relief height and elevation, etc., 2 geomorphologic regions may be further subdivided 13 geomorphologic sub-regions.
