摘　　要：由于伊犁谷地特有的地质环境和气象水文特征,滑坡、泥石流等地质灾害频发。无人机遥感技术具有能快速获取高质量、高分辨率遥感影像的特点,借助无人机遥感技术对新源县阿尔善村山体滑坡进行现场扫描,通过采集滑坡后的地表三维点云数据获取数字高程模型(DEM),同时运用栅格空间分析技术,将平滑前的DEM与平滑后的DEM进行栅格运算,定量计算出滑坡土方量为25422.79 m^(3)。研究成果为当地的地质灾害风险评估、监测预警、排查防治与指挥救援等提供客观、详实的数据资料。Due to the unique geological environment and meteorological and hydrological characteristics of Yili Valley,landslide,debris flow and other geological disasters often occur.UAV remote sensing technology can quickly obtain high-quality and high-resolution remote sensing images.This paper uses UAV remote sensing technology to scan the landslide in Aershan village,Xinyuan county.By collecting the three-dimensional point cloud data after the landslide,DEM are obtained.At the same time,grid spatial analysis technology is used,By grid calculation of DEM before and after smoothing,the quantity of landslide earthwork is 25422.79 m³.Researcher provide objective and detailed data for local geological disaster risk assessment,monitoring and early warning,investigation and control,command and rescue.
