英文摘要	This project report results of the first leaf water delta O-18 and delta D time series of the woody plant Quercus aquifolioides undertaken on the southeastern Tibetan Plateau (STP). The data show that delta D of leaf water underwent less enrichment than delta O-18 relative to precipitation and soil water, and could inherit the delta D value characteristics of precipitation far better than delta O-18. The leaf water delta D values were strongly modified by evaporative enrichment in response to lower and more drastically changing relative humidity observed outside of the rainy season. In comparison, leaf water delta D values more closely tracked those observed in the monsoon precipitation (acted as source water) in the rainy season. Our findings suggest that leaf water delta D values from the STP were sensitive to the Indian monsoon activities, and the effects of relative humidity and the Indian monsoon precipitation should be considered for stable isotopes in tree ring cellulose or other biomarkers studies on the STP.
