摘要

大箐梁子一带有着众多明显的古地震遗迹。它们的相互叠加和重复，说明该地是一个曾多次发生强震的震中区。从古地震遗迹的初步研究可知，目前地处大箐梁子北侧一带的活动断层侵蚀作用十分活跃，造成了邛海水系袭夺则木河上游水系，并迫使分水岭不断南移。
There are numerous obvious remains of ancient earthquake along the Daqing-ridge. They overlay and duplicate each other.Some of places are the epicentral regions in which many earth-quakes happened.Now the arching structures are forming along the Daqing-ridge according to ap-proach on the remains of ancient earthquake. The erosion processes with fault activity are awfully dynamic along the north of the ridge. It makes clear that the Qionghai river-system has eroded the upper reaches river-system of the zemuhe and that the dividing range has kept coming to move to south.
