Abstract: The relationship of larch (Larix olgensis) radial growth in Changbai Mountains with climate change was assessed by dendrochronological techniques including correlation functions and single-years analysis.The results showed that larch growth was sensitive to environmental change,and temperature was the primary factor affecting larch growth.The larch growing in high and low elevations had a significantly different response to temperature.In high elevation,larch growth was significant correlated to the mean temperature of June,but in low elevation,it had a more complicated relationship to the environment.Besides the mean temperature of April and May,the temperature of last June and September and the humid index of last September significantly correlated with the larch tree ring-width.Therefore,it was not the same relationship of the same tree species with different environmental gradients.

Key words: Tree ring, Climate change, Changbai Mountain
