英文摘要 | Long-term high-resolution climate proxies are essential for understanding climate variability on the Tibetan Plateau (TP), where few long-term climate records are available. In this paper, we describe a summer (August) temperature reconstruction over the period 1385-2002 based on a tree-ring width chronology of Balfour spruce (Picea likiangensis var. balfouriana) on the southeastern TP created using the Regional Curve Standardization method. The reconstruction explains 44.7% of the variance in the instrumental temperature records during the calibration period (1962-2002), and captures temperature variability over a broad region of the TP. Warmer than average Augusts were found during the periods 1446-1494, 1509-1522, 1553-1567, 1797-1812, 1845-1905 and 1918-2002. Cooler than average Augusts occurred from 1385-1416, 1426-1445, 1495-1508, 1523-1552, 1568-1686, 1695-1718, 1725-1796, 1813-1844 and 1906-1917. A warming trend in the 20th century was unprecedented during the past six centuries. The reconstruction closely matched other tree-ring summer temperature reconstructions from neighboring regions, as well as patterns from ice-core delta(18)O data, and fluctuated in synchrony with Northern Hemisphere temperature reconstructions.
