摘要
九寨沟地处青藏高原向四川盆地陡跌的两大地貌单元的过渡地带 ,经笔者等调查可划分出高山山地地貌、高山坡地地貌和高山河谷地貌等三种地貌类型及十种成因类型的第四纪堆积物 ,并对其分布规律、特征进行描述。首次划分了区内第四纪地层 ,探讨其演化过程。为研究九寨沟自然资源的演化发展以及合理利用和保护提供了基础资料。
Jiuzhai Valley lies in transitional zone between the Qinghai Xizang Plateau and the Sichuan basin Landforms in Jiuzhai Valley may be divided into high mountain,high mountain slope and high mountain valley types The Quaternary sediments may be divided into 10 genetic typeswhose distribution and features are outlined Quaternary stratigraphic division is made firstly These provide basic data for the research into evolution of natural resources and their reosonable utilization and protection
