In recent years, researchers have focused on the applications of uncrewed aerial vehicles (UAVs) in environmental remote sensing tasks. However, studies on glacier monitoring using UAV technology are relatively scarce, especially for high mountain glacier monitoring. To explore the feasibility of UAV technology for high mountain glaciers, four UAV surveys were deployed on two glaciers of the central Tibetan Plateau. Based on the images retrieved by UAV in 2017 and 2019, orthomosaics and digital elevation models were produced to quantify the length, area and elevation changes in the ablation zone of these two glaciers at different times. Additionally, we utilized several Landsat scenes to derive glacier changes over the last 30 years and combined these with the UAV data to assess the advantages and disadvantages of UAV technology in mountain glacier monitoring.

结合无人机和陆地卫星数据评估青藏高原中部的冰川变化

近年来，研究人员专注于无人驾驶飞行器（UAV）在环境遥感任务中的应用。然而，利用无人机技术进行冰川监测的研究相对较少，尤其是高山冰川监测。为了探索无人机技术在高山冰川上的可行性，在青藏高原中部的两个冰川上部署了四次无人机调查。根据无人机在2017年和2019年检索到的图像，制作了正射镶嵌图和数字高程模型，以量化这两个冰川在不同时间消融带的长度、面积和高程变化。此外，
