Abstract:: In this study, the research substances, including snow melt, rain water, soil water, groundwater, were collected from Fukang Station of Desert Ecology of Chinese Academy of Science located in the southern part of Gurbantunggut desert. During the experiment, we analyzed the ratio of the oxygen and hydrogen stable isotopes, researched the feature of changing in stable isotope of the precipitation, soil water and groundwater. The results show that: in spring, the δ¹⁸O in soil water which belongs to top soil with 10 cm is affected by the one in precipitation directly, and the tendency of its change resembles to that of the δ¹⁸O in precipitation. The differences among δ¹⁸O in groundwater in different seasons are not noticeable. Furthermore, the impact degree of different factors on the variations of stable oxygen isotope in the process of water cycle and their interaction are evaluated in the study, which provides an example for the application of stable isotopic technique to the study on water cycle.
