| 摘 要： | 利用树轮稳定碳同位素组成（δ１３Ｃｔ）序列可以较为灵敏地记录降水变化的特性，以长白山树轮δ１３Ｃｔ序列为降水变化的自然记录体，探讨太阳活动对长白山乃至东北季风气候区降水变化的影响。研究指出：１）２００年来长白山及东北季风气候区降水变化有准２２年的周期性波动；２）东北季风气候区里，东南季风强弱变化具有准２２年的周期性振荡；３）直接控制东南季风强弱变化的西太平洋副热带高压的活动可能具有相应的准２２年周期

| Abstract: | sing stable carbon isotopic composition series of tree ring sampling from Changbai Mountain as natural record of meteoric water, appling characteristics of this record effectively reflecting precipitation variations to studies of the influences of solar activities on precipitation variations in monsoon climate region of the northeastern China,we concluded that:1) there is a quasi-22-year periodicity in the precipitation-series in monsoon climate region of the northeastern China including Changbai Mountain since recent two hundred years ,2) the quasi-22-year periodicity exist in the evolution of southeastern monsoon stength of monsoon climate region of the northeastern China. |
