摘　　要：皖南山区是安徽省地质灾害高发区和地质灾害重点防治区,地质灾害识别对皖南山区地质灾害治理和防治工作至关重要。笔者对皖南山区17个滑坡点、5个崩塌点和2处泥石流等典型地质灾害点进行调查,采用无人机倾斜摄影实景建模技术,对灾害点进行摄影测量,建立地质灾害体的三维影像模型。通过三维影像模型和野外调查,总结归纳了皖南山区主要地质灾害无人机影像识别标志。三维影像建模的识别标志可以为皖南山区突发性地质灾害精准识别和快速勘查、救援等工作提供数据支持。The southern mountainous area of Anhui Province is a place with high incidence of geological hazards and a focus of prevention and control of the hazards.Geo-hazard identification is very important to its control.In this paper,an investigation was carried out on 17 landslide spots,5 collapse spots and 2 debris flow spots in the area.UAV oblique photography modeling technology was applied to surveying the spot to establish the 3D image model of the hazard body.Through 3D image modelling and field investigation,the UAV image identification marks of major geo-hazards in the area were summarized,and such identification marks can serve as a data support for accurate identification,rapid exploration and rescue of sudden geo-hazards in the southern mountainous area of Anhui Province.
