树轮氢氧同位素方法是过去环境气候变化研究领域内的主要技术手段之一，因其时间分辨率高，反映环境参数多，准确定量的优点，近年来日益受到重视。笔者在系统深入地探讨树轮与环境间氢氧同位素分馏机制的基础上，详细介绍了树轮氢氧同位素方法在环境气候变化研究中的应用 Tree-ring hydrogen and oxygen isotope method is one of the main technical means in the field of past environmental climate change research, because of its high temporal resolution, reflecting the advantages of many environmental parameters and accurate quantification, more attention has been paid in recent years. On the basis of systematically exploring the hydrogen-oxygen isotopic fractionation mechanism between tree-ring and environment, the author introduces the application of tree-ring hydrogen and oxygen isotopes in the study of environmental climate change
