摘　　要：Phosphorus(P)is a key biological nutrient and probably the ultimate limiter of marine productivity during Earth history.In recent years,a wealth of new knowledge has revolutionized our understanding of the global P cycle,yet its longterm evolution remains incompletely documented.In this paper,we review the effects of three major controlling factors on the long-term evolution of the global P cycle,i.e.,tectonics,marine redox conditions,and bio-evolution,on the basis of which a five-stage model is proposed:StageⅠ(>~2.4 Ga),tectonic-lithogenic-controlled P cycling;StageⅡ(~2.4 Ga to 635Ma),low-efficiency biotic P cycling;StageⅢ(~635 Ma to 380 Ma),transitional biotic P cycling;StageⅣ(~380 Ma to near-modern),high-efficiency biotic P cycling;and Stage V(Anthropocene),human-influenced P cycling.This model implies that the earlier-proposed Ediacaran reorganization of the marine P cycle may represent only the start of a-250-Myr-long transition of the Earth's P cycle(StageⅢ)between the low-efficiency biotic mode of the Proterozoic(StageⅡ)and the high-efficiency biotic mode of the Phanerozoic(StageⅣ).The development of biologically-driven,high-efficiency P cycling may have been a key factor for the increasing frequency and volume of phosphorite deposits since the late Neoproterozoic.
