摘　　要：临汾断陷盆地位于山西地堑,新构造运动强烈且地层发育较齐全,在整合多源地质灾害数据的基础上,通过对临汾的岩土体类型、地质构造、地形地貌以及气候气象等孕灾背景的研究,剖析了崩塌、滑坡、泥石流的多种成灾机理:岩土体在外营力作用下成为山地地质灾害的主要物源,加之临汾地质构造复杂、地势陡峻,在暴雨冲刷、冻融作用以及人为破坏之下极易成灾.文章旨在通过对临汾山地地质灾害的研究,以期为预警防治管理体系的健全提供理论基础和可靠依据.The Linfen fault basin is located in Shanxi graben,the neoteetonics is strong and the strata of the system are developed, On the basis of integrating the data of multi-source geological hazard, this paper analyzes the rock soil mass types, geological structure, topography and geomorphology,meteorologY of Linfen Factors such as the background of the disaster, to clarify the collapse,landslides and debris flow disaster mechanism, rock and soil mass under the exogenic forces to become a major source of geological calamity of mountain region, combined with Linfen complicated geological structure and steep topog raphic features, under the rain erosion,freezethaw action and artificial damage easily. This paper aims to provide a theoretical basis and reliable basis for the sound management system of Linfen through the study of geological calamity of mountain region in Linfen.
