| 摘 要： | 通过对天山中部地区连续多年的GPS观测分析,得到了该监测区相对欧亚板块的运动速度场及应变场分布情况。计算表明天山中部地区内部断裂两盘的运动方向以婆罗科努断裂为界,北部各断层表现为拉张特征,南部总体表现为聚合特征。

| Abstract: | We find the movement velocity field and distribution of strain field in the middle Tianshan mountain relative to Eurasia plate by analyzing the continuous observation datum of GPS in the region.The result shows,the Poluokenu fault is the borderline for the movement direction of fault,the characteristics of the faults are pull apart in the north part,but in south part the characteristics are convergence. |
