树木年轮与全球变暖的关系研究进展

Research on Relationship Between Tree-ring and Global Warming

树木年轮宽度、密度、同位素含量等都与气候因子温度、湿度以及其他成分的变化有复杂的相关关系。总结了树木年轮的几种研究方法在全球温度变化中的应用,同时利用树木年轮分析对全球变化研究中存在的问题做了简要的探讨,并对未来全球变化条件下年轮年代学研究的方向作了展望。

There exist complicated correlations between tree-ring width,density,relative isotopecomposition and climatic factors,such as temperature,humidity and the change of other component,etc.Research methods of dendrochronology and its application in global temperature change were reviewed in this paper.Existing problems in global change research or disputed problems were also discussed.In addition,the future trends of tree ring study in global change research were prospected.
