| 摘 要： | 通过对拉萨、日喀则地区两条基线的观测结果分析，得到了拉萨地块近南北向地壳形变率为（７．０±２．３）ｍｍ／ａ及近东西向（７．４±２．３）ｍｍ／ａ的形变速率，与震源机制解的结论十分接近。同时监测到相对于拉萨南北向７．３ｃｍ和东西向４．１ｃｍ的震后形变位移，显示出ＧＰＳ在地震监测及与地震相关的地壳形变研究的广阔前景

| Abstract: | The present-day crustal deformation of the Qinghai-Xizang plateau and its margins has been intensely studied in geoscience community. The Global Positioning System (GPS) offers a revolutionary method to deepen our knownledge on the crustal thichness that resulted from the collision between Indian and Eurasia plates as well as the subsequent penetration of Indian into the rest of Asia. Since 1991, Institute of Seismology, State Seismological Bureau, has performed several GPS mesurements in the center Qinghai-Xizang plateau with the objectives of monitoring crustal movement using a high-precision GPS geodetic network and these GPS surveys will contribute to the studies of tectonic and geodynamics. |
