Abstract Eight tree-ring width chronologies have been set up based on the tree-ring samples of Larix sibirica Ledeb. collected from the eastern Altay region, northern Xinjiang of China. The correlation analysis showed that there are significant correlation between tree-ring width chronologies and mean temperature in period of June to July at Qinghe Weather Station, and the correlation coefficient between Zhuolesayi tree-ring chronology and the mean temperature is the largest (0.555, P<0.0001). The mean June July temperature during 1613-2006 in the eastern Altay region can be better reconstructed by using Zhuolesayi t and Zhuolesayi t+3 tree-ring standardized chronologies. Cross validation test proved that the reconstruction functions are stable and reliable. The reconstructed series suggested that:(1) The variation of mean June July temperature in eastern Altay region had seven warm stages and seven cold stages in these 394 years. (2) The change of mean June July temperature existed significantly quasi-periodic change of 2.7~3.7 years, 43.7 years and 52.4 years. (3) The reconstructed series showed 10 abrupt changes in 1669, 1691, 1714, 1732, 1762, 1781, 1802, 1919, 1939 and 1963.
