As the third pole of the world,the Tibetan Plateau has been the hotspot of the large-scale climate change research. The long-lived needle-leave trees widely distributed in the plateau provide important proxies for past climate change. Three tree-ring width chronologies and their composite chronology of Picea likiangensis var. balfouriana were established in Changdu district of northeastern Tibet. Correlation and response analysis between tree-ring width index and climatic factors revealed that the total precipitation from previous October to May in the current year was the dominant climatic factor on their radial growth. The linear transfer function (n = 32,R~2 = 52.9%,F = 33.7) was introduced to reconstruct the precipitation history during 14602011. The reconstructed series indicated that there were six distinct wet periods (1512 - 1533,1551 - 1630,1659 - 1729,1771 - 1790, 1838 - 1862,1976 - 2011) and five drought periods (1460 - 1511,1591 - 1614,1730 - 1770,1791 - 1837, 1892 - 1930). Spatial representativeness analysis demonstrated the reconstructed series could reflect regional precipitation change in the eastern Tibet (94°E ~ 100°E,29°N ~ 33°N). Comparison between this study and other tree-ring based precipitation records in the surrounding area confirmed the consistency of lasting drought in the early 19th century with the wetting trend since the mid-1980s. However,the longest wet period (1659 - 1729) and the drought period in the early 20th century in this study were inconsistent with other two precipitation records. The significant wetting trend in the recent 20 years was probably resulted from the enhancement of vertical convention due to land surface warming. The inconsistency among tree-ring precipitation records was caused by both the distinct localized precipitation and the limited size of studied area,which lies in the interaction area of the South Asian monsoon and the westerlies.
