　　简    介：

　　Isotope discrimination levels in trees over the Tibetan plateau reveal highly persistent spatial patternsthat are slightly modified by short-term variations in hydroclimate, especially by evapotranspiration and available soil moisture. Millennium-long oxygen isotope chronologies over the Tibetan plateau indicate a strong moisture contrast between the humid marginal areas of the Tibetan plateau and the interior regions. Humid periods coincide with glacier advance periods of monsoonal type glaciers. After the Little Ice age maximum around AD 1780, the stable isotope chronologies converge and show a common trend of increasing dryness, indicating a stronger common climatic forcing by the Asian summer monsoon.
