英文摘要	In the reconstruction of past climate using stable carbon isotope composition (delta C-13) in tree ring, the responses of the stable carbon composition (delta C-13) of multiple tree species to environmental factors must be known detailedly. This study presented two delta C-13 series in annual tree rings for Chinese hemlock (Tsuga chinensis Pritz) and alpine pine (Pinus densata Mast), and investigated the relationships between climatic parameters and stable carbon discrimination (Delta C-13) series, and evaluated the potential of climatic reconstruction using Delta C-13 in both species, in a temperate-moist region of Chuanxi Plateau, China. The raw Delta C-13 series of the two species was inconsistent, which may be a result of different responses caused by tree's inherent physiological differences. After removing the low-frequency effects of CO2 concentration, the high-frequency (year-to-year) inter-series correlation of Delta C-13 was strong, indicating that Delta C-13 of the two tree species were controlled by common environmental conditions. The Delta C-13 series of the species were most significantly correlated with temperature and moisture stress, but in different periods and intensity between the species. During the physiological year, the impacts of temperature and moisture stress on Delta C-13 occur earlier for Chinese hemlock (previous December to February for moisture stress and February to April for temperature, respectively) than for alpine pine (March to May for moisture stress and April to July for temperature, respectively). In addition, in temperate-moist regions, the control on Delta C-13 of single climatic parameter was not strongly dominant and the optimal multiple regressions functions just explained the 38.5% variance of the total. Therefore, there is limited potential for using delta C-13 alone to identify clear, reliable climatic signals from two species.
