中文摘要: 为了研究树木生长对气候变化的响应,选取长白山北坡3个海拔高度建立了臭冷杉Abies nephrolepis的年轮差值年表。通过年表特征及响应函数分析,探讨不同海拔臭冷杉径向生长对气候变化的响应。结果表明,温度是影响海拔分布上限(1 760 m)臭冷杉生长的主要影响因子,年轮宽度指数与上年9月和当年5月的平均温呈显著正相关,与降水没有显著关系:在中海拔(1 250 m),年轮宽度指数与温度和降水都没有呈现出显著相关关系;在海拔分布下限(780 m),降水是主要的影响因子,年轮宽度指数与上年9月和10月的降水量呈显著正相关,与温度没有达到显著相关。未来气候变化有利于臭冷杉的径向生长,有利于长白山暗针叶林生产力的增加。
英文摘要: We established residual chronologies of Abies nephrolepis at three altitudes in Changbai Mountain to study responses of tree growth to climate change. According to analyses of chronology characteristics and response function, we detected responses of radial growth of A. nephrolepis to climate change along the elevational gradient. The results showed that temperature is the main factor affecting tree growth at the upper limits (1760 m), by presenting significant and positive correlations between ring-width index and mean temperature in previous September and current May. At the middle distribution (1250 m), neither temperature nor precipitation significantly affected radial growth of A. nephrolepis. At the lower distributional limits (780 m), precipitation mainly affected tree growth, ring-width index was significantly and positively correlated with precipitation in previous September and October. Based on the current prediction of future climate change in Changbai Mountain, the radial growth of A. nephrolepis would benefit from changes in temperature and precipitation, promoting productivity of spruce-fir forest in the area.
