英文摘要	The lapse rate of water isotopes is used in the study of the hydrologic cycle as well as in the estimation of uplift of the Tibetan Plateau. The greater elevation contrast in the Southern Himalayas allows for a detailed discussion about this lapse rate. We analyze variations of delta O-18 in precipitation and river water between 1320 m and 6700 m elevations in the Southern Himalayas, and calculate the specific lapse rate of water delta O-18. The results show that the multi-year average lapse rate in precipitation over this region is 0.15aEuro degrees/100 m. The one-year average lapse rate is 0.17aEuro degrees/100 m from three sites along the Southern Himalayas. The two results agree, but are much lower than the global average of 0.28aEuro degrees/100 m. This work also shows that there is a difference in precipitation delta O-18 lapse rate between the monsoon and non-monsoon seasons. The calculated precipitation lapse rate is much lower than that in surface water.
