Water Stable Isotopes in an Alpine Setting of the Northeastern Tibetan Plateau
Hydrological processes produce effects on water resources in inland mountainous regions. To understand the important segments of the water cycle, a group of Chinese scientists carried out a relevant study in Qilian Mountains which were located in the northeastern edge of the Tibetan plateau, precipitation, soil, plant, river, and groundwater were collected during the plant growing season of 2016. All samples were collected on a monthly basis, except precipitation, which was collected on a per event basis. Soil and plant water were extracted using the automatic water extraction system LI-2100 (LICA United Technology Limited, Beijing, China). The δ18O and δ2H of all water bodies were measured using the liquid-water isotope analyzer DLT-100 (Los Gatos Research, CA, USA).Automatic Cryogenic Vacuum Distillation Water Extraction System LI-2100The local meteoric water line (LMWL) of the three sampling sites, using six regressions (OLSR, MA, RMA, PWLSR, PWMA, PWRMA), are presented in Figure 2....
