| Abstract: | Based on the data of δ18O in surface snow, snow pits, meltwater and the glacier-fed river water at Baishui Glacier No.1, Mt. Yulong, the isotopic
fractionation behaviors in the typical monsoonal temperate glacier system in winter and summer were compared. The results
indicate that the isotopic fractionation degree in summer is greater than that in winter, suggesting that the snow/ice melting
is more intense in summer. Moreover, whenever it is in winter or summer, from surface snow to meltwater, and to glacier-fed
river water, the gradient of δ18O with altitude gradually increases. This shows that the degree of isotopic fractionation gradually strengthens when surface
snow is being converted into meltwater and finally into glacial river water, which suggests that the influence of post-depositional
processes on δ18O gradient in the monsoonal temperate glacier region differs spatially.
