资源简介：
The data set integrated glacier inventory data and 668 Landsat TM/ETM+/OLI images, and adopted manual visual interpretation to extract glacial lake boundaries within a 10-km buffer from glacier terminals using ArcGIS and ENVI software, normalized difference water index maps, and Google Earth images. It was established that 27,205 and 30,121 glacial lakes in HMA, with sizes of 0.0054–6.46 km2, covered a combined area of 1806.47 ± 2.11and 2080.12 ± 2.28 km2 in 1990 and 2018, respectively.The current glacial lake inventory provided fundamental data for water resource evaluation, assessment of glacial lake outburst floods and gacier hydrology research in the mountain cryosphere region.
