英文摘要	The altitude effect of delta O-18 is essential for the study of the paleo-elevation reconstruction and possible to be solved through modern process studies. This study presents new delta O-18 results from southeast Tibetan Plateau along two transects, the Zayu transect and the Lhasa-Nyang transect, with delta O-18 data from June to September representative of monsoon period and delta O-18 data during the rest of the year of non-monsoon period. Altitude effect outweighs the longitude and latitude effects in determining regional delta O-18 variation spatially. Relevant delta O-18 data from previous studies in the nearby region have also been combined to comprehensively understand the influence of different moisture sources on delta O-18 from local scale to regional scale. The delta O-18 in surface water in the southeast Tibetan Plateau and its nearby regions influenced by the Indian summer monsoon shows that single dominant moisture source or simple moisture sources lead to smaller altitudinal lapse rate, whilst growing contributions from local convection to precipitation enlarge delta O-18-altitude rate. It thereupon reveals the significance of the Indian summer monsoon to the altitude effect of delta O-18 in surface water, and the complicated effect of local convection or westerlies evolution to the variation of altitudinal lapse rate. Paleo-monsoon evolution therefore should be considered when altitude effect is applied to paleo-elevation reconstruction for the Tibetan Plateau.
