摘要: <正>对采自气候为非限制性因子地区的柳杉树轮稳定碳同位素比 δ13 C进行气候响应分析。用排除法消除大气二氧化碳中δ13C的变化对柳杉树轮δ13C变化的影响后,建立残差年序列RE,并结合西天目山气象站的气象记录,分析了树轮δ13C年序列对气候要素的响应。结果表明:西天目山地区树轮 δ13C的高频振荡与 11、12月最高气温的平均值,1、2、3月降水总和以及6、7月降水总和显著相关,在一定程度上反映了东亚季风对该区的影响大小。可见气候非限制性因子地区树轮稳定碳同位素组成年序列同样可以作为气候变化指针。

Abstract: Respond analysis is carried out between δ13 C on δ-cellulose of tree rings, obviated the influence of CO2 concentration changing in non-limiting factor area and climatic factors. Significance correlation is shown between high-order of oscillating of treering δ13C values and average air high temperature of November and December, total precipitation from January to March and total precipitation of June and July, which inferred the influence of East Asian Monsoon. The results indicate that the sequence of tree ring carbon isotope in non-limiting factor area can also be used as indicator of the climatic change.
