| 英文摘要 | It is currently suggested that climate change on the northeastern tibetan plateau (tp) was influenced alternately by the monsoon and the westerlies. however, the mechanisms driving holocene climate change on the tp remain unclear, since the extent of the influence of individual atmospheric circulation systems has not yet been clearly defined because of the shortage of high-quality paleoclimatic records. this is especially true in the central tp, where only a few ice core and paleolimnological records are available. here, we present a decadal-resolution temperature record from dagze co in the central tp for the past 2000years, based on the unsaturation index of long-chain alkenones, using an updated temperature calibration, and a record of precipitation isotopes from compound-specific isotope ratios of leaf waxes. the centennial-scale variation of the temperature and precipitation isotope records captures well-known climatic events over the past 1000years, for example, the little ice age', which was cooler and drier than the medieval warm period'. however, the relationship between temperature and the precipitation isotope records differed during the interval at 2000-1000cal. yr bp compared to the past 1000years, probably because of changes in precipitation seasonality and the additional influence of the westerlies on the central tp. in addition, the temperature records exhibit a prominent 210-year cyclicity, suggesting a possible influence of solar radiation on temperature variability. |
