| 摘 要： | 根据乌鲁木齐地区 2 0 0 0年、2 0 0 1年两期 GPS网资料及其它资料处理结果 ,讨论了乌鲁木齐现阶段应变场及监测区的断层水平运动情况。分析结果认为乌鲁木齐地区地壳整体主要受 NW方向的主压应力作用 ,乌鲁木齐测区大部分 GPS观测点以乌鲁木齐红山观测点为中心呈顺时针方向运动。

| Abstract: | Based on two stages of GPS data during 2000 and 2001 in the Urumqi area and other data, recent strain field in Urumqi and the horizontal movements of the faults in monitoring region were analyzed. The result shows that the whole crust of the Urumqi area is mainly effected by principal compressive stress in NW direction, and the majority of GPS stations in Urumqi monitoring region are clockwise moving taking Hongshan observation station in Urumqi as center. |

| Keywords: | GPS monitoring net Horizontal deformation Principal compressive stress Shear stress Urumqi |
