摘要
浮游有孔虫壳体钙化强度是全球碳循环研究中的关键要素,也是重建古海洋环境和评估全球变化的重要代用指标。影响浮游有孔虫壳体钙化过程及强度的因素众多,目前的研究方向和研究方法存在诸多不确定性,导致其在古海洋学研究中的应用受到限制。本文系统总结了浮游有孔虫壳体钙化的生物学机理、钙化强度的环境驱动因素以及钙化指标的测量方法,全面梳理了浮游有孔虫钙化指标的影响因素和研究进展。同时,深入探讨了该指标在古海洋学中的应用前景,并分析了在当前全球变化背景下海洋碳酸盐系统的变化对于浮游有孔虫壳体钙化的潜在影响,为未来相关研究提供了理论基础和方向指引。
The calcification intensity of planktonic foraminiferal shell plays a crucial role in the global carbon cycle and serves as an important proxy for reconstructing palaeoceanographic environments and assessing global climatic changes.However,multiple environmental and biological factors influencing this process,along with uncertainties in current research approaches,have limited the extensive application of calcification index in palaeoceanographic studies.This paper provides a comprehensive review on the biological mechanisms underlying foraminiferal calcification mechanism,the environmental drivers on the calcification intensity,and the methodologies used to quantify relevant indicators.Recent advances and key influencing factors in this field are also systematically summarized.Furthermore,we discuss the proxy’s potential in palaeoceanographic reconstructions and its implications on monitoring the ocean carbonate system under the increasing global CO_(2)background,which presents a theoretical foundation and guidance for the future research.
