摘　　要：本文通过蒙自五里冲水库库区构造岩动力学研究，配合年代学测定，得出区内最晚一次强烈构造活动的主压应力轴方向为北西向，断裂的活动方式以左旋剪切为主。Through dynamic study of fault tectonite in Wulichong reservoir region of Mengzi combining with absolute dating,Some results are obtained that the principal compression axes of last strong tectonic movement was in NW direction,and the pattern of fault movement was mainly lift-lateral shear.
