| 摘 要： | 对伽师及帕米尔东北侧地区的GPS监测网进行加密和复测,采用GPS高精度数据处理软件进行解算,获得了高精度的观测结果,基线的相对精度达10-8～10-9.根据观测结果,初步得到了该地区的现今地壳形变速率图及各基线矢量的时间序列.结果表明,伽师地区向北推移、塔里木盆地对天山的正向挤压是该区地壳运动的主要方式.

| Abstract: | The GPS monitoring network in the Jiashi region and the northeastern area to Pamir has been densed and repeated.Through computing with the highaccuracy GPS data processing software the observation results are acguired.The relative accuracy of base line reaches 10 -8 ~10 -9 .From these results the map of present crustal deformation rate and the time sequence of each baseline vector are solved primarily.The results show that the Jiashi region is moving northwards and the normal compression of the Talimu Basin to Tianshan is the major mode of the crustal movement in this area. |
