| 摘 要： | 根据1993年和1995年对青藏高原地壳运动进行的两期 GPS 监测的实测结果,分析了青藏高原现今地壳水平运动情况,并将其与不同地质运动模型结果进行了比较。结果表明,青藏高原现今地壳水平运动速率和方向与地质结果符合很好。目前,青藏高原大约以38.6mm/a 的速度向北东方向运动。

| Abstract: | The Qinghai-Xizang Plateau is located in the collision zone along the Eurasian and Indian plates two GPS campaigns were carried out in this area in 1993 and 1995. The crustal movement behaviors in the Qinghai-Xizang plateau are discussed based on the reasults of campaigns.The GPS measurements show that the Qinghai-Xizang platean moves at about 38.6mm/a to Siberia northeastward at present,this result is in agreement with the kinematic model derived from geophysical evidence. |
