摘要：通过响应函数分析和多元回归分析等年轮气候学方法,研究北京地区侧柏年轮宽度和年轮密度对气候变化的响应。结果表明:侧柏年轮宽度序列和年轮密度序列对气候变化相当敏感。前一年10月到当年9月的月平均气温和月降水量的响应函数模型可解释年轮宽度变化的58.45%,年轮密度变化的77.81%。夏季降水对侧柏年轮宽度有显著的正效应,而对年轮密度则表现出负效应。与降水的影响相反,夏季气温对侧柏年轮宽度表现出显著的负效应,对年轮密度表现出显著的正效应。其中,当年7月的气温和降水对侧柏年轮宽度和年轮密度的作用尤为显著。说明侧柏的年轮宽度和年轮密度均可用于年轮气候学研究,且年轮密度包含的信息量高于年轮宽度。
Response of ring width and ring density to climate variance was studied by theories and techniques of dendrochronology including response functions analysis and multiple regression analysis for Platycladus orientalis in Beijing, China. The results showed that ring width series and ring density series of P. orientalis was sensitive to climate variance. The climate response models were established with mean monthly temperature and total monthly precipitation from the preceding November to the current October. The models explained 58.45 % and 77.81% of the ring width total variance and ring density total variance, respectively. It.was found that ring width has a significant positive response to precipitation and a significant negative response to temperature from June to August during the current growing season. The reverse was true to the ring density, it had a negative response to temperature and a significant positive response to precipitation. Response of ring width and ring density to climate variance was evident especially July. The results indicated both the ring width and the ring density of P. orientalis are very useful variables for the study of dendroclimatology.
