摘要
对采自天目山的柳杉树轮进行交叉定年后 ,得到树轮的 δ13 C、δD年序列。利用附近杭州站的相对湿度资料 ,分析其对树轮δ13 C、δD的影响。结果表明 :树轮稳定同位素与相对湿度之间有着显著的反相关关系。利用其较好的相关性 ,通过建立回归方程可以重建当地一百多年来的相对湿度序列 。
Based on cross-dating tree rings age from Tianmu Mountain,Zhejiang Province,the tree α-cellulose δ 13C and δD time series are obtained.We analyzed the response of the δ 13C and δD to climate elements using meteorology data from nearby weather station.The results suggest that there are distinct relations of opposite phase between δ 13C,δD series and relative humidity.The multiple regression method is employed to reconstruct the historical climate and to analyze the climatic change in the last 160 years at the Tianmu Mountain.
