| 摘 要： | 介绍了国内外在古海洋溶解氧研究领域内的主要方法和动态，并分别对沉积构造法、沉积硫法、同位素法、微量元素法、稀土元素法、有机地球化学法及古生态法等研究方法进行了全面的分析和评论，指出,古海洋溶解氧含量重建对于理解大洋循环、古气候、生物绝灭、地质事件以及有机质演化具有十分重要的科学意义，它有赖于溶解氧含量的替代性指标的建立、富氧问题研究的进一步深入以及综合分析气圈、水圈、沉积圈、生物圈等各子系统内部及它们之间氧的物质输送和转化。

| Abstract: | Major studying methods and their new development related to palaeo ocean dissolved oxygen are summarized and discussed. Studying methods discussed include bioturbation, sulfur/carbon ratio, degree of pyritization (DOP), sulfur and carbon isotopes, trace element, rare earth element (mainly cerium anomaly), organic geochemistry and palaeo ecology (mainly dissolved oxygen index). It is proposed that reestablishment of the paleo ocean dissolved oxygen will greatly benefit to understand paleo ocean current, paleo climate, bio events, and organic evolution, which will largely be relied on establishment of substitute markers for dissolved oxygen, knowledge of oxic environment and oxygen cycle of Earth science system. |
