Abstract
Three tree-ring STD chronologies of Abies faxoniana were developed from Songpan region Sichuan Province, and a regional chronology(RC) was established based on the three STD chronologies. The calculation shows that the tree-ring width was significantly correlated with temperature, and the RC had the highest correlation( r =0.576, P R adj2=32%, N =59, F =28.33). In the past 310 years, there were 8 warm periods and 7 cool periods. According to analysis of temporal and spatial correlation, it indicated that the reconstructed series with good spatial and temporal representation. Our reconstruction was validated by other tree-ring based temperature reconstructions from the surrounding area, glacier advances and retreats, and the documented climate disaster events. MTM analysis shows that there exist periods of 2-3 a, 26 a, quasi-33 a and quasi-40 a cycles.
