摘　　要：文县阳山金矿带处于文县弧形构造内,而文县地质构造复杂,断层活跃,降雨集中,灾害频繁。本文旨在充分收集该地区地质灾害历史成果资料的基础上结合遥感解释、地面勘测等手段,进行诸如滑坡等主要地质灾害的实地调查分析。通过查阅资料和现场调查,明析地质灾害的分布、发育规律以及形成机理,完善灾害数据库,为该地区防灾减灾提供依据。The Yangshan gold belt is located in the arc structure of Wen County,and Wenxian has complex geological structures,active faults,concentrated rainfall and frequent disasters.This article aims to collect the historical results of geological disasters in the area,combined with remote sensing interpretation,ground survey and other means,to conduct on-site investigation and analysis of major geological disasters such as landslides.Through reference to data and on-site investigations,the distribution,development and formation mechanism of geological disasters are clearly analyzed,and the disaster database is improved to provide a basis for disaster prevention and mitigation in the region.
