摘要: 西南岩溶山区,植被茂密,地形陡峻,传统地面岩溶调查手段效率低且危险性高。本文采用机载LiDAR技术,获取四川某抽水蓄能电站库区激光点云和光学影像数据,结合室内解译和野外复核,开展区域岩溶识别工作。查明了库区内岩溶发育分布情况,根据岩溶形态划分为岩溶漏斗、岩溶洼地及落水洞3类。基于已有资料和LiDAR数据成果提取库区高程、坡度、坡向、构造、岩性及汇水区因子,并分析了岩溶发育的分布规律。结果表明,无人机机载LiDAR技术可精准快速识别抽水蓄能电站库区岩溶分布特征,为水电站前期勘察设计提供了新的技术手段。

Abstract: In the Karst mountain area of southwest China, the vegetation is dense and the terrain is steep. The traditional ground Karst investigation methods are inefficient and dangerous. In this paper, the airborne LiDAR technology is used to obtain the laser point cloud and optical image data of the reservoir area of a pumped storage power station in Sichuan, and combined with the indoor interpretation and field review, regional Karst identification is carried out. The development and distribution of Karst in the reservoir area are found out, which can be divided into Karst funnel, Karst depression and sinkhole according to the Karst morphology. Based on the existing data and LiDAR data results, the elevation, slope, aspect, structure, lithology and catchment area factors of the reservoir area are extracted, and the distribution law of Karst development is analyzed. The results show that the UAV airborne LiDAR technology can accurately and quickly identify the Karst distribution characteristics in the reservoir area of the pumped storage power station, and provide a new technical means for the early survey and design of the power station.
