摘　　要：磷作为地球生命DNA和RNA的核心组成部分,是地质历史时期海洋表层初级生产力的主要限制性营养元素,对全球大气-海洋氧化还原状态及气候变化具有重要调节作用.总结了海洋中磷的源及汇,阐述了磷组分的构成及其在研究磷的埋藏、转化与循环中的应用,分析了古老地层中磷的沉积特征与生物-环境演化的关系,明确了不同地质时期磷循环特征、机制及其与大气-海洋-生态之间的反馈作用,这对于认识生命与地球环境的关系具有深远意义.Phosphorus(P),as a central component of DNA and RNA of life on earth,is the major limiting nutrient for marine productivity on geological time scales,and plays an important role in regulating the global atmosphere-ocean redox state and Earth's climate.This paper summarizes the source and sink of P in the ocean,and expounds the composition of P speciation and its application in the study of P burial,diagenetic transformations and marine P cycle,and analyzes the sedimentary P characteristics in the ancient strata and their links with life-environment evolution,which helps clarify features and mechanism of P cycling in different geological periods and its feedback on atmosphere-ocean-ecology system.This is of far-reaching significance for understanding the relationship between life and Earth's environment.
