Abstract:This paper revealed the response policy of tree after fired to meteorological factors through the relationship between tree\|ring widths of Pinus koraiensis after fired in Changbai Mountain and the climate factors.The model was built to assess the effect of increasing temperature to the radial growth of P. koraiensis after fired. The results show that the P. koraiensis after fired was significant negative correlated to mean monthly maximum temperature of current Feb, June,July and Sep.,and positive correlated to the mean monthly minimum temperature of Jan., May, Sep. and Oct. in this year and monthly precipitation of June and Aug. in the last year. There was no significant relationship between the growth of P. koraiensis after fired and mean monthly temperature. The monthly maximum temperature in current growth season is the main influence factor to the radial growth of P. koraiensis after fired. When the temperature increase to 4℃,14% of the annual growth of P. koraiensis after fired will be decreased. Therefore, it can be concluded that the P. koraiensis after fired is sensitive to extreme temperature,and the global warming will decrease the annual growth of P. koraiensis after fired.
