| 英文摘要 | Tree ring delta C-13 as a climate proxy is widely used for palaeoclimate research, however, its temporal stability response to the climate change remains unclear under more than one limited factors on tree growth. Here, we used a millennium tree-ring delta C-13 chronology combining two annual-resolution delta C-13 chronologies since 1800 from long-lived Qilian juniper (Sabina przewalskii) to assess its instability of the climate signal in the northeastern Qinghai-Tibetan Plateau. Tree-ring delta C-13 chronologies were strongly correlated with the regional mean April to August temperature from 1956 to 2008, but the associations were absent within the period 1901 to 1955 values in the CRU TS dataset. Comparison of the millennium-long delta C-13 series with reconstructed Asian temperatures also demonstrated that the delta C-13 chronology exhibited climate signal temporal instability. Substantial oscillations were revealed using a frequency-dependent analysis and 51-year running correlation analysis from the millennium-long tree-ring delta C-13 and delta O-18 series. Dual-isotope approach indicated that stomatal limitations created a statistical significant positive correlation between tree-ring delta C-13 and delta O-18, but photosynthetic rate may be dominant when the correlations were not significant. Our results suggest that tree-ring delta C-13 series in the northeastern Qinghai-Tibetan Plateau is responded instability to temperature variations in the past 1000 years. (C) 2016 Elsevier B.V.
