| 摘 要： | 上扬子北缘的大巴山地区是秦岭造山带和扬子地块长期相互作用的地区,构造变形和地貌特征记录了印支期、燕山期,尤其是喜山期构造运动和地貌响应过程。本文以地理信息系统（GIS）为平台,通过对数字高程数据（DEM）的处理,结合地质图、构造水系图等各种数据,对大巴山及其前缘盆地的构造地貌特征进行综合分析研究,以坡度、地形起伏度、高程图和剖面图的统计为主,分析其构造地貌特征。研究表明,大巴山自晚燕山—喜山期前陆褶皱冲断形成以来,经历了多次隆升过程,特别是自喜山期以来,大巴山共经历了至少三次大规模的隆升。

| Abstract: | Dabashan mountains at the north edge of the Upper Yangtze Block lies in a long-term interactive area where the Qinling orogenic belt is in touch with the Yangtze Block,in which the tectonic deformation and the geomorphic features have recorded the process of tectonic movements from Indosinian,Yanshanian and Himalayan tectonic events particularly.Based on Geographic Information System(GIS)in this paper,a detailed research of the structural geomorphology of Dabashan mountains and its foreland basins has been ... |
