英文摘要	Arid basins in the alpine-cold area have their unique environmental settings and special groundwater circulation system. Sources, components and their variation of recharge processes for most rivers and groundwater of seasonal scale are still unknown in response to climate warming. Stable H and O isotopes were sampled monthly in river water and groundwater, and water table fluctuations were monitored over a complete seasonal cycle from dry to wet season conditions in the Nalenggele River catchment in the western Qaidam Basin, China. The primary objectives of our study were to demonstrate and explain the mechanism governing the rapid circulation in the groundwater system. Distinct seasonal fluctuations in the water table with corresponding stable isotopic variations can be observed in the alluvial fan of the Nalenggele River catchment. The recharge mechanism is related to the coincidence of several favourable hydrological conditions including an abundant recharge water source from summer precipitation and glacial snow melt in the high Kunlun Mountains, large-scale active faults, a volcanic crater, and other macro-structures that act as favourable recharge conduits, a large hydraulic head, and the presence of >100 m of unconsolidated sand and gravel acting as the main aquifer. Abundant and rapid renewable groundwater resources are potential water sources for future development in the Qaidam Basin.
