根据凹陷中心的变化探讨青藏高原现代构造活动特征

APPROACHING THE FEATURES OF NEOTECTONIC MOVEMENT BASED ON CHANGES OF DEPRESSION CENTERS IN QINGHAI-XIZANG PLATEAU

摘要:

本文通过对青藏高原北部地区分布的大量文化层、河流变迁等资料进行的分析对比,圈定了各盆地的现代凹陷中心,研究了该地区的现代构造活动特征及其与地震危险区的关系。这对拓宽烈度区划工作具有一定的参考意义。

Abstract:

In this paper,based on analysis and comparison of data about cultural remains and drainage changes in the north of Tibet plateau,the recent depression centers of basins are delimited and feature of neotectonic movement and its relation to seismic risk zone are studied, which will contribute to develop the intensity regionalism work.
