英文摘要	This study investigated the variations of stable isotopes (delta O-18 and delta D) in precipitation at Deqin on the southeastern margin of the Tibetan Plateau. The results show that correlations between stable isotopes in precipitation and temperature vary during different seasons. In comparison, an apparent inverse correlation between stable isotopes and precipitation amount exists throughout different seasons. Hence, the "amount effect" appears to have significantly controlled the stable isotope variations in precipitation over the entire sampling period, rather than the "temperature effect". The overall temporal variations of delta O-18 and delta D in precipitation from Deqin are similar to those from a southern station at Xishuangbanna. Both stations demonstrate considerably depleted precipitation delta O-18 values in the summer as a consequence of intense Asian summer monsoon activities. However, at Xishuangbanna, the occurrences of the timing and duration of the depleted delta O-18 values, as well as the negative surface lift index values, occur earlier and last longer than those at Deqin. These results indicate that the Asian summer monsoon onset is later and that the duration of the monsoon activities is shorter at Deqin relative to Xishuangbanna. (C) 2015 Elsevier B.V.
