Abstract: The convergence of Indian and Eurasian plates,especially the crustal activity in the Qinghai-Xizang Plateau has attracted geoscientists attention.This paper atempts to use the advantage of wide-sight and continuity of view on the Landsat images to analyse the spatial distribution of the lineament and their geometric patterns for avialable information.Combined with geological,geophydical and seismological data,a further investigation is made for the main characteristics of the acnvitity of blocks and their boundary faults in the plateau and their generations.

摘要： 自印度洋板块和欧亚板块汇聚后,特别是上新世以来,青藏高原的地壳又如何活动,一直是人们感兴趣的研究课题。本文试图利用陆地卫星影象具有视域广和连续性的优点,对所提供丰富、清晰的线性信息,着重分析线性构造空间展布及其组合的几何式样,进而结合地质、地震和地球物理资料探讨高原地区地块和块缘断裂活动基本特征及其形成机制。
