Abstract: We developed a tree-ring width chronology (KLD) of Larix sibirica from the high elevation forests of the central Altay Mountains in northern Xinjiang, China. Based on the correlation between the KLD chronology and local meteorological data, we found tree-ring width had significant and positive correlations with mean June temperature (r=0.658, P<0.001). Regional early summer temperature history (1579-2009) was therefore reconstructed, which explained 43.2% of the instrumental variance for the period 1962-2009. During the past 431 years, the reconstruction documented eight warm periods and eight cold periods. According to the results of spatial correlation analysis, it revealed that the temperature reconstruction can represent the early summer temperature changes in Altay Mountains. Power spectrum analysis indicated the existence of some decadal (71.5 and 95.3 year) and interannual (2.3, 2.4 and 3.9 year) cycles.
