摘　　要：生态系统中磷的关键来源是土壤化学风化过程中磷酸盐的溶解(简称“磷风化”),这些磷也是全球尺度关键营养元素循环的核心,在一定程度上影响生物圈的大小。从现代陆地生态系统磷循环出发,简要概述显生宙热室地球陆地生态系统磷风化的最新研究进展。在此基础上,探讨磷风化增强对碳循环的影响,并对未来陆地生态系统磷循环进行展望。研究以期为探索显生宙极热事件、碳循环等提供理论参考,也为评估未来磷肥使用与农业可持续发展提供科学支撑。Phosphorus(P)released from soils via chemical weathering(referred to as P weathering)plays a critical role in the global cycling of key elements and significantly influences the size of the Earth’s biosphere.Grounded in the modern terrestrial P cycle,this paper provides an overview of recent research on terrestrial P weathering during the Phanerozoic hothouse conditions.Furthermore,it examines the potential impacts of accelerated P weathering on the carbon cycle and proposes future research directions for understanding the terrestrial P cycle.This paper aims to contribute theoretical insights for exploring the dynamics of Phanerozoic hothouse conditions and the carbon cycle,while also offering scientific support for optimizing phosphorus fertilizer use and promoting sustainable agricultural practices in the future.
