摘　　要：文章以湖南省花垣县地质灾害风险普查项目为依托,利用遥感解译手段结合湖南省1:1万地质灾害调查和风险评价项目部分崩塌地质灾害点的野外调查工作。以ArcGIS平台为基础建立三维遥感影像模型,总结花垣县县域内崩塌地质灾害的影像特征和解译标志。根据解译标志对研究区进行地质灾害遥感解译,解译结果在野外得到验证,解决了1:5万卜如坪崩塌地质灾害在册隐患点找不到危岩体风险源的尴尬历史遗留问题。结果表明:在地质灾害风险普查及调查过程中三维遥感影像模型的应用具有重要的指导意义和前瞻性。Based on the geological disaster risk survey project of Huayuan County,Hunan Province,Combined with the field survey of rockfall geological disaster sites of hunan province 1:10000 geological disaster survey and risk assessment project by remote sensing interpretation means.On ArcGIS platform,a 3D remote sensing model was established to summarize the image characteristics and interpretation signs of the rockslide geological disasters.Remote sensing interpretation of geological hazards in the study area is carried out according to the interpretation indicators,and the interpretation results are verified in the field,it solved the embarrassing historical problem that the 1:50,000 Bu-ru-ping rockfall geological disaster could not find the risk source of dangerous rock mass at the listed hidden danger point.The results show that 3d remote sensing technology has important practical and guiding significance for geological disaster risk survey and geological disaster investigation.
