生物标志物稳定氢同位素是一种比较新的古环境指标,越来越多的研究者利用生物标志物稳定氢同位素重建了陆地和海洋中古水循环的变化。在陆地上,生物标志物δD值可以用来重建降雨δD值、古海拔以及蒸散作用大小或者湖泊水的输入输出平衡。在海洋中,生物标志物δD值的变化能更好地反映与其相关的生物和环境信息。培养实验以及现场数据显示生物标志物δD值能很好地反映表层海水δD值以及表层海水盐度的变化。许多研究者也利用海洋中生物标志物δD值重建了长时间尺度降雨量以及表层海水盐度的变化。对近年来生物标志物稳定氢同位素的研究进展,尤其是在海洋古环境重建中的应用进行了总结。
Biomarker stable hydrogen isotope is a relatively new paleoenvironmental indicator. More and more researchers have used biomarkers to stabilize hydrogen isotopes to reconstruct paleoclimate cycles in land and sea. On land, the δD value of the biomarkers can be used to reconstruct the δD values of precipitation, paleo-elevations and evapotranspiration or the input-output balance of lake water. In oceans, changes in the δD values of biomarkers better reflect the biological and environmental information associated with them. The experiment and the field data show that the δD value of biomarkers can reflect the δD value of surface seawater and the salinity of surface seawater. Many researchers also use the δD values of biomarkers in the ocean to reconstruct long-term rainfall and salinity changes in the surface water. In recent years, the progress of research on stable hydrogen isotopes of biomarkers has been summarized, especially in the reconstruction of marine paleoenvironment.
