The present study generates a glacial lake inventory of Arunachal Pradesh, Eastern Himalaya, India using Landsat 8 Operational Land Imager (OLI) images (2016-2018). The study reveals that there are in total 1532 (> 0.001 km2) glacial lakes, covering an area of 93.7 km2. Glacier erosion lakes are the most dominant type with 1268 glacial lakes (82.8%) and an area of 76.8 km2 (∼82%). About 50% of the lakes are located in the four districts of eastern Arunachal Pradesh, while ∼16% in the three districts of central and ∼33% in the four districts of western Arunachal Pradesh. The western Arunachal Pradesh has mixed patterns of glacial lakes types, whereas the erosion lakes dominate the eastern and central Arunachal Pradesh. The current inventory can serve as a baseline database for understanding glacial lake-related flood hazard studies in Arunachal Pradesh.

印度东喜马拉雅地区阿鲁纳恰尔邦冰川湖泊的清单和空间分布

本研究使用 Landsat 8 Operational Land Imager (OLI) 图像（2016-2018）生成了印度喜马拉雅东部阿鲁纳恰尔邦的冰川湖清单。研究表明，冰川湖共有1532个（>0.001平方公里），面积93.7平方公里。冰川侵蚀湖泊是最主要的类型，有1268个冰川湖泊（82.8%），面积76.8平方公里（~82%）。约 50% 的湖泊位于阿鲁纳恰尔邦东部四区，约 16% 位于中部三区，约 33% 位于阿鲁纳恰尔邦西部四区。阿鲁纳恰尔邦西部有多种冰川湖类型，而侵蚀湖在阿鲁纳恰尔邦东部和中部占主导地位。
