摘要：稳定碳同位素技术因具有示踪、整合和指示功能,检测快速、准确,在生态学、水文学和地球科学研究领域中得到了广泛应用。本文综述了稳定碳同位素技术在土壤碳循环、植物生理生态反应、树木对气候变化的响应、同位素模型等研究领域的新应用,发现在环境因子和基因型之间的交互作用对δ13 C的影响、水分利用效率对多因素相互作用的响应、多同位素源分析模型不确定性等方面还有一些问题亟待解决,期望本文对稳定碳同位素在生态系统中应用现状、存在问题以及前景展望方面的总结对今后的相关研究有所裨益。
Stable carbon isotopes serve as tracers,integrators,and indicators for earth science.Moreover,rapid and accurate measurements of these isotopes are increasingly available.Studies of stable carbon isotopes demonstrate great potential to be more widely applied in the fields of ecology,hydrology and geoscience.Despite several previous reviews on the applications of various isotope systems,rapid development of new techniques and continuous expansion of these techniques to new applications in the field necessitate the publication of timely updates to summarize recent advances in applied stable carbon isotope research and technology.This paper summarizes new applications of stable carbon isotopes to investigate soil carbon cycles,plant physiology and ecology,and tree responses to climate change,and reviews recent progress in stable carbon isotope models.We also highlight areas for improving stable carbon isotope research,including consideration of the effects of interaction between environmental factors and plant genotypes onδ13 C,the response of water use efficiency to multi-factor interactions and the uncertainty of multi-source isotopic models.We anticipate that this updated review of recent applications,existing problems and current prospects of stable carbon isotopes to ecosystem research will be beneficial for future research in this area.
