英文摘要Ground ice is extensive in the permafrost regions of the Qinghai-Tibet Plateau. It is useful for regulating water resources in Plateau regions, and affects the ecological water environment in permafrost areas. This research investigated the isotope characteristics of ground ice on the Qinghai-Tibet Plateau. In this work, 73 samples of ground ice from 4 boreholes were collected to analyze and compare stable isotopes with precipitation and river water. The results show that isotope composition of ground ice varied in narrow ranges, ranging from -13.16 parts per thousand to -9.08 parts per thousand for delta O-18 and from -103.61 parts per thousand to -69.92 parts per thousand for delta D. The isotope composition of subsurface ground ice is slightly more positive than that of deep-layers due to the fractionation of freezing. Based on the recharge relationships among ground ice, precipitation, and river water, subsurface ground ice is partly recharged by precipitation and river water. However, the isotope variations of deep-layer ground ice may be the result of isotope fractionation under different climate conditions. (C) 2013 Elsevier Ltd and INQUA. All rights reserved.
