研究了长白山地区火烧后存活下来的红松(Pinus koraiensis)与气候因子的关系,揭示火干扰后树木生长对气候要素的响应策略,建立生长量与气候要素的模拟方程,定量估算火干扰后温度变化对火烧红松径向生长的影响.结果表明,火烧红松年轮宽度与当年2月份、生长季最高温度显著负相关,与1月、5月、9月份和10月份的月最低温度显著正相关,与上一年6月和8月份的月降水量显著负相关,与平均温度的相关未达到显著,生长季的月最高温度是影响火烧红松径向生长的主要原因,且当温度上升4℃时,火烧红松的年生长量降低14%.推断火干扰后红松生长对温度较敏感,全球变暖有可能导致火烧红松的生长量降低.

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.
