摘　　要：采用无人机航空摄影测量技术对某石场占用及损毁林地进行调查。经现场检验,无人机航空摄影测量效率与传统人工测量方法相比提高3倍以上,利用倾斜摄影能够精确反映石场现状地貌,测图精度达到1:500比例尺。UAV aerial photogrammetry technology was used to investigation the occupation and damage of woodland in a quarry.The field test showed that the UAV photogrammetric efficiency was more than3times higher than that of the traditional manual surveying method.The use of oblique photography could accurately reflect the status of the quarry,and the mapping accuracy reached1:500scales.
