Yulong Snow Mountain National Field Observation and Research Station for Cryosphere and Sustainable Development, set up by Northwest Institute of Eco-Environment and Resources of Chinese Academy of Sciences, is located in Lijiang City in southwest China's Yunnan Province. Since 2006, researchers have regularly monitored the condition of the Baishui River No. 1 Glacier and its surrounding environment on the snow mountain.

According to Wang Shijin, a glaciologist and head of the station, part of the meltwater of the Yulong Snow Mountain flows to Lijiang ancient city, then flows into the Jinsha River from Heqing County in Dali Bai Autonomous Prefecture. And the meltwater of Baishui River No. 1 Glacier merges into the Lanyue (Blue Moon) Valley in Lijiang, then flows into the Jinsha River near the Tiger Leaping Gorge, supplying water to the upper reaches of the Yangtze River.
