Yulong Snow Mountain is located in the north of Lijiang City, Yunnan Province, in the southeast margin of the Qinghai-Tibet Plateau, belonging to the Hengduan Mountain system, is the southernmost of the Qinghai-Tibet Plateau, the lowest latitude of the Eurasian continent of modern Marine glacier area. There are 19 modern glaciers distributed in the region, among which the largest glacier is Baishui No. 1 Glacier, which is located on the eastern slope of the main peak of Yulong Snow Mountain, with a length of 2.7 kilometers and an area of 1.52 square kilometers. The snow line height is between 4800 and 5000 meters. Studies have shown that due to the impact of global warming, the Whitewater 1 glacier has been shrinking at a rate of about 27 meters per year in the past 10 years, which is one of the fastest melting glaciers in the world. The Yulong Snow Mountain Glacier and Environment Observation and Research Station of the Chinese Academy of Sciences began to carry out long-term observation of changes at the end of Baishui Glacier 1 in 1999, and began to carry out systematic observation of mass balance, borehole ice temperature, glacier meteorology and glacier hydrology in 2008. This topic includes all kinds of observation data of Baishui No. 1 glacier in Yulong Station since 1999.
