摘要
树木年轮的宽度、密度、图像分析、同位素含量等都与气候因子温度、湿度以及大气成分的变化成复杂的相关关系。本文总结了树木年轮分析的几种主要研究方法以及在全球气候变化、大气污染以及重建大气CO2 浓度中的应用 ,同时利用树木年轮分析对全球变化研究中存在的问题、争议等作了简要的探讨 ,并对未来全球变化中的年轮年代学研究的方向作了展望。
Complicated correlations exist between tree-ring width, density, image analysis, relative isotope composition, and climatic factors,such as temperature, humidity and the change of atmosphere component, etc. Research methods of dendrochronology and application in global climate change, air pollution, reconstructing concentration of air CO\-2 were summarized in this paper. Existing questions in global change study or disputed problems were also discussed. In addition, the future trends of tree ring study in global change research were prospected.
