摘要: 植物组织中的稳定性碳同位素组成(d13C)整合记录了气候因子和影响植物碳同化以及气孔导度的生理因子的相关信息。应用稳定碳同位素技术可以揭示环境变化中的一些相关信息。本文回顾了不同的环境因子和植物d13C的关系,以及这些关系在气候变化研究中的应用,同时进一步讨论了这项技术在重建历史气候和预测未来气候变化中的作用。

Abstract: Carbon isotope composition (d13C) of plant tissues constitutes an integrated record of the miscellaneous climatic and physiological factors that affect carbon assimilation and stomatal conductance. We can assess environmental changes through making a carbon isotope analysis of plants. Here we present a literature review on the relationship between different environmental parameters and d13C in plants. We will also consider the applicability of some of these relationships, as well as for the assessment of climate change dynamics and its implications.
