Abstract：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.
