摘要：

Annual oak (Quercus robur L.) latewood delta(13)C values are presented for the period 1895-1994 for two sites different hydrological characteristics in southwest Finland. No appreciable anthropogenic C-13 depletion was observed in the time-series. delta(13)C indices record high-frequency common forcing better than lower-frequency forcing. High-frequency fluctuations in the delta(13)C indices are highly correlated with climatic variables. Cross correlation analysis of tree ring delta(13)C indices and climate variables show that there is no significant difference (p<0.01) in the climate response of tree ring delta(13)C indices between the two sites. This work demonstrates that significant climate signals are contained in isotopic measurements of trees whose ring-widths contain little or no such information.
