摘　　要：纳雍地区为典型的喀斯特丘陵地貌,植被茂密,地形陡峭,传统地质调查方法存在一定困难且工作效率低。该文采用机载LiDAR和倾斜摄影技术,获取场区激光点云和五镜头光学影像,生成高精度数字高程模型(DEM)、数字表面模型(DSM)、高分辨率三维实景模型(3D-Model)等成果,从宏观上判别场区地质环境,同时通过微小变形查明场区植被覆盖下地质灾害隐患。此次研究基于综合遥感技术共识别出22处滑坡、6处人工边坡及1处岩溶空洞等地质灾害隐患,为纳雍地区新能源项目等重大项目场区选址及后期建设运营提供新的技术支撑。The Nayong area is a typical karst hilly terrain with dense vegetation and steep terrain.Traditional geological survey methods have certain difficulties and low work efficiency.This paper uses airborne LiDAR and oblique photography technology to obtain laser point clouds and five lens optical images of the site,generate high-precision digital elevation models(DEM),digital surface models(DSM),high-resolution three-dimensional model(3D-Model),and other results,and macroscopically distinguish the geological environment of the site.At the same time,geological hazards under vegetation cover in the site are identified through small deformations.Based on comprehensive remote sensing technology,this study identified a total of 22 geological hazards such as landslides,6 artificial slopes and 1 karst cavity,providing new technical support for the site selection and subsequent construction and operation of major project sites such as new energy projects in Nayong area.
