摘要
By measuring and comparing δD, δ18O, and 3H values of different sections in Lhasa River, we can trace its water resource and water environment. We have concluded that the upper reaches of the Lhasa River are mainly supplied by melt-water (with lower 3H value and mineralization degree) and underground water (with lower 3H value and higher mineralization degree). The middle reaches are mainly supplied by rainwater (with higher 3H value and mineralization degree).
