Abstract: We present the theory and method for inversing the kinematics parameters of a fault zone and then use this method to study the present kinematic characteristics of the Altun fault zone The results show that the Altun fault zone is generally compressive in the direction of S14癊,its compressive rate is 1.13 mm/a,and the rate of its left lateral shear movement is 0.17mm/a

Key words: Inversion of seismic moment tensor, Altun fault zone, Tectonic stress field

摘要： 利用地震矩张量反演断裂形变带运动学参数的方法,应用于阿尔金断裂带现今运动学特征的研究。结果表明,阿尔金断裂带以沿S14°E的压缩运动为主,压缩速率为1.13mm/a;同时,断裂带还以0.17mm/a的速率发生左旋剪切运动。
