摘要
作为世界上最高最大最活动的青藏高原,以其独特的自然地理条件吸引了广大学者和科研人员的关注,在此地区开展的各项研究工作.本文主要介绍了利用GPS监测青藏高原及邻区所得到的速度矢量场.观测结果表明:高原南北向收缩、高原物质东流、高原东部地区地壳物质相对喜马拉雅汇聚区作大规模的顺时针旋转等高原动力学特征.并就其产生原因进行了初步分析.
The Qinghai-Tibet is the highest, the biggest and the most active Plateau over the world. Many scientists pay attention to its unique topography and natural characteristics, and carry out their research in to this region. Based on results of GPS observations, the velocity field of crustal movement in the Qinghai-Tibet Plateau and its southeast foreland is showed in this paper. The GPS monitoring of crustal movement documents the dynamic characteristics of the Qinghai-Tibet Plateau and its southeast foreland, including north-south-direction concentration in the plateau, east-ward material-flow in the plateau, and clockwise-rotation of crustal material in the eastern plateau around convergence area in Himalayans. And origin of the dynamics has preliminarily been analyzed.
