Stable isotopic evolutions of ground ice in permafrost of the Hoh Xil regions on the Qinghai-Tibet Plateau

Climatic warming-induced permafrost (ground ice) thaw is expected to considerably alter hydro−geomorphology and the water cycle on the Qinghai-Tibet Plateau (QTP). A unique feature of permafrost is the substantial enrichment of ground ice, which can be used to directly indicate the past climate and hydrological cycle. However, essential characteristics of ground ice on the QTP are not yet understood. The stable isotope technique was used to...
