摘要
本文在１９８９－１９９０年两次实地考察的基础上，结合前人和邻区资料，对研究区内的地质构造背景等作了较为系统研究，揭示出地区地质构造演化特征。并论述该地区的地质构造发展历史，为阐述其地形地貌的形成以及相关的自然和经济地理规律提供地质背景的根据。但因地形、交通、气候和生活条件等所限，地质研究程度尚低，特别是属上游的西部地段。
This article is based on two times on the field investigation in 1989 and 1990,combinesmaterials of predecessors and neighbouring area,and makes a systematic study on structuralbackground within rescarching area,It reveals evolution feature of geological structure. Besides,it dicusses development history of the geological structure,and it provides geological bacd-ground basis to expound its topography formation and the related natural and economic geography law. But the limitation of topography,transportation,climate and living condition,levelof geological minerals study is still low,especially those beling to western section of upstream.
