英文摘要	The growing season of high-elevation forests will presumably lengthen in response to warming. However, little is known about long-term effects of an extended growing season, particularly on the Tibetan Plateau. Based on a strong correlation between the daily mean temperatures at an automatic weather station at timberline (4,390 m a.s.l.) in the Sygera Mts., recorded since 2007, and at the meteorological station at Nyingchi (3,000 m a.s.l.), recorded since 1960, we modeled the variation in daily mean temperature at the timberline back to 1960. The onset and end of the growing season at the timberline were determined by the first and the last day within a year when the mean daily air temperature equals or exceeds, respectively falls below, +5 A degrees C for at least 5 days. From 1960 to 2010, the estimated length of the growing season at the timberline has significantly extended by 21.2 days, resulting mainly from a significant delay of its end (by 14.6 days) rather than from an earlier onset (by 6.6 days). Nevertheless, the variation of the length of the growing season did not exhibit any significant effect on the radial growth of Smith fir at the timberlines. Thus, tree-ring width is still a reliable proxy for summer temperature.
