陕西省洋县地质灾害发育特征及影响因素分析

摘要

Based on the analysis of geological hazard survey data and geological data,the paper summarizes the development and distribution characteristics of geological hazards in Yang County,and analyzes the formation conditions and influencing factors.The results show that the formation lithology and the types of rock and soil,geological structure,topography and geomorphology are the basic conditions for the formation of geological hazards,and hu-man engineering activities and rainfall are the main inducing fac-tors.The analysis results have important reference significance for preventing and controlling geological hazards in Yang County.%在地质灾害详查成果和地质资料分析的基础上,总结了洋县地质灾害的发育分布特征,分析了其形成条件及影响因素.结果表明,地层岩性及岩土体类型、地质构造、地形地貌是地质灾害形成的基本条件,人类工程活动、降雨则是主要诱发因素.分析结果对洋县的地质灾害防治工作具有重要参考意义.
