摘　　要：对川、滇毗邻地区新构造运动作区域让运动学研究认为，该区在总体隆升过程中，沿断块间主干活动断裂带的强烈构造运动与断块内部的相对稳定同时并存。依据对重点断裂剖面的观察和年代样品鉴定结果，对区内活断裂的特征及活动时期作了综合归纳，重点阐述了则木河（南段）－小江断裂（北段）的几何学和运动学特征。According to regional dynamic research of current tectonic movement,we consde that thestrong tectonic movement of main active fault and relative stability of fault block insidecoexist. Based on the observation of major fault section and the determination results of yearssample, the active fault characteristics and the active period in the area have beencomprehensively summed up.We set forth the geometry and dynamics charateristics ofZemuhe-Xiaojiang fault.
