摘要
总结了树轮氢氧同位素的分馏原理及其时间序列和空间变化与气候变迁之间的关系。研究表明，树轮氢氧同位素组成的变异反映了源水同位素组成、温度、相对湿度和降水量的变化。同时，对今后树轮同位素的发展方向作了展望。
The fractionation model of hydrogen and oxygen isotope in plants and the recent progress in treering hydrogen and oxygen isotope research are overviewed. The composition of hydrogen and oxygen isotope in tree ring are correlated with the isotopic composition of source water, temperature,relative humidity or the amount of meteoric water, so it could provide favorable conditions to reconstruction paleoclimate with high resolution,accurate dating and good continuity, which may not be substituted by other mediums. In addition, the future trends in treering hydrogen and oxygen isotopic research are presented, including interregional cooperation,the comparison with other mediums and interdiscipline and so on.
