Relationship between δ D and δ18O in precipitation on north and south of the Tibetan Plateau and moisture recycling

The local meteoric water line (MWL) has been established from north to south of the Tibetan Plateau based on the measured results of delta D and delta(18)O in precipitation and river water, and the relationship between MWL and moisture origins discussed. The spatial and seasonal variations of d in precipitation and river water on the Tibetan Plateau have been studied. Results show that the spatial and seasonal variations of d between north and south of the Tanggula Mountains are related to different moisture origins and water recycling.
