Stable isotope values of hydrogen and oxygen in different water bodies at different elevations in eastern Qilian Mountains（2018-2023）

Twelve sampling sites were set up in the eastern Qilian Mountains (101◦40'47" -- 102◦23'5"E, 37◦28'22" -- 38◦14'2" N) (Fig.1). From April 2018 to October 2023, a stable isotope monitoring network was established at four different elevation gradients: 2058-2390m, 2390-2721m, 2721-3448m, and 3448-3637m.

在祁连山东部设置了12个采样点（东经101°40′47″—102°23′5″，北纬37°28′22″—38°14′2″）（图1）。2018年4月至2023年10月期间，研究人员在四个不同海拔梯度（2058-2390米、2390-2721米、2721-3448米和3448-3637米）建立了稳定同位素监测网络。
