摘要: 运用相关函数及单年分析等树木年轮气候学方法,研究了长白山北坡落叶松径向生长与气候变化的关系.结果表明,落叶松的生长对环境变化相当敏感,温度是影响其生长的主要因子.但不同海拔的落叶松对温度的响应明显不同.高海拔分布的落叶松只与当年6月的温度指标显著相关,而低海拔的落叶松与环境的关系相对复杂,除当年的4、5月外,上一年的6、9月温度以及上年9月的湿润指数都显著影响其生长.这说明不同环境梯度上的同一树种对气候变化的响应不尽相同.

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
