Abstract: The recent movement along the Zemuhe fault and deformation markers for its qualitativeidentification are discussed in the paper.Our investigation shows that the recent movement alongthe fault is characterized by clear segmentation and the fault has been bisected into southern andnorthern segments bounded at Daqing site. The northern segment shows mainly stick-slip move-ment and the southern segment shows creep movement.The spatial distribution of vertical dis-placement rate is evidently different on the fault segments and hence can be used as indicators foridentifying the recent movement pattern on the fault.The relative displacement rate is also an in-dicator for identifying the recent movement pattern along the fault.

摘要： 根据地壳形变测量资料,探讨了则木河断裂的现今活动方式及其定性的地形变鉴别标志问题。结果表明:则木河断裂的现今活动具有明显的分段性特征,即以大箐为界分为南北两段,北段以粘滑活动为主,南段以蠕滑活动为主;沿则木河断裂带垂直位移速率空间分布特征的显着差异,可以作为鉴别断裂现今活动方式的标志之一,其位移速率的相对大小,可作为鉴别断裂现今活动方式的一种参考标志。
