| Abstract: | The fractionation model of hydrogen and oxygen isotope in plants and the recent progress in tree-ring 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 tree-ring hydrogen and oxygen isotopic research are presented, including inter-regional cooperation, the comparison with other mediums and interdiscipline and so on. |
