We sampled two sites in different landscapes, one is located at the forest line at ca. 4200 m above sea level beside an incised valley, and the other at the plateau surface, ca. 4500 m in elevation. Comparisons of statistical parameters between two sites and their tree ring index correlation coefficient with meteorologic data of DaoCheng shows that the latter site exhibits higher value than the former one. These indicate that those trees growing along the valley side may be more susceptible to local environment, and those on the plateau surface can provide reliable record for regional climate. Based on the latter chronology, a 903a long annual mean temperature (Tmean) series (1115-2017 CE) was reconstructed. It is the longest width chronology reconstructed by JS at present. The entire sequence shows consistent warm-cold patterns with other temperature reconstructions of the TP, Asia, and Northern Hemisphere. The warmest (coldest) period occurred at 1998-2017 CE (1115-1145 CE), respectively. There was no doubt that temperature raised sharply since the end of the 20th century. In addition, the sequence demonstrates multi-decadal, decadal and inter-decadal variations, further multi-taper method reveals dominant periodicities are 147, 36, 18, 7 and 2-2.6a, likely been affected by the Atlantic Multidecadal Oscillation and solar activity. The forcing of volcanic eruptions resulted to subsequent 1-3 years temperature drops.
