摘　　要：[目的]研究元谋断裂对东山泥石流沟的控制作用,为该区泥石流防治提供科学依据。[方法]基于东山地区沿线沟谷的现场调查,分析研究元谋断裂对东山泥石流沟的控制作用。[结果]元谋断裂与泥石流沟空间位置关系对泥石流的发育存在着影响,对东山地形地貌的形成起控制作用,对东山地层岩性及其工程特性起控制作用,对元谋县气候的形成起控制作用。[结论]元谋断裂对东山地区泥石流的形成起到控制作用,它决定了东山地区泥石流频发的特性。[Objective] Studying the control effect of Yuanmou fracture on debris flow in Dongshan area, to provide scientific basis for debris flow control in this area. [Methods] Based on the investigation of the valley along the Dongshan area, the control effect of Yuanmou fracture on Dongshan debris flow gully was studied. [Results] The relative position of debris flow gully to Yuanmou fracture has influences on the development of the debris flow, which can control the formation of Dongshan topography and geomorphology, can control the lithology and engineering characteristics of Dongshan formation and can control the formation of climate in Yuanmou County. [Conclusion] The Yuanmou fracture plays a controlling role in the formation of debris flow in Dongshan area, the frequent debris flow in Dongshan area can be attributed to it.
