摘要：

青藏高原是全球海拔最高、形成时代最新和面积最广阔的高原,作为青藏高原典型的地貌特征,层状地貌成因研究对高原隆升、环境气候演化过程的认识具有非常重要的作用,通过野外调查和已有观测数据分析,对层状地貌形成进行探讨,重点从高原现今地貌特征分析的角度,提出主平面和山顶面形成于高原隆升过程中。青藏高原是在印度大陆与欧亚大陆俯冲碰撞的强烈挤压环境下,内外动力地质作用共同作用的结果,其内动力地质作用具有差异性整体隆升的特征。希望能对青藏高原隆升过程的深入研究提供新的思路和依据。

Abstract:

The QinghaiTibet Plateau is the highest, the latest and the most extensive plateau in the world. The layered landscape is a typical landform feature of the QinghaiTibet Plateau; the study of its formation is of great significance for understanding the process of QinghaiTibet Plateau uplifting and the evolution of the climate. This paper discusses the formation of the layered landscape on the QinghaiTibet Plateau based on the field investigation and the observed data analysis. We focus on the analysis of nowadays landform features of the QinghaiTibet Plateau and put forward that the main surface and the peak surface were formed in the plateau uplifting process. Under the intensive compression by the subduction and collision between the India plate and the Eurasian plate, the coactions of internal and external processes caused the uplift of the QinghaiTibet Plateau. The internal process had the characteristics of the differentially wholly uplifting. We hope this study could provide some new ideas and basis for the research on the uplifting of the QinghaiTibet Plateau.

Key words: QinghaiTibet Plateau; planation surface; steplike landforms; plateau uplift
