摘要
磷(P)的生物地球化学循环是整个生物圈物质能量循环的重要组成部分,在水环境质量变化和生命演替过程中起着决定性作用。传统理论普遍认为磷循环是以^(+Ⅴ)价态的磷酸盐(P^(+Ⅴ))为主导的沉积型循环,忽略了磷化氢(P^(-Ⅲ))、次磷酸盐(P^(+Ⅰ))和亚磷酸盐(P^(+Ⅲ))等价态低于^(+Ⅴ)的无机还原态磷(IRP,inorganic reduced phosphorus)形态,致使当前对水体P循环的认识存在明显的“缺失”。本综述在目前获得的新研究和新发现的背景下,对水环境中IRP的赋存形态、来源和组成、检测方法、时空分布、迁移转化、环境行为与效应等方面的研究现状进行阐述并对IRP的发展态势进行展望,以期丰富和完善湖泊磷循环理论并提供关键信息,推动对磷循环相关研究的发展,为湖泊水环境保护和治理提供参考。
The biogeochemical cycling of phosphorus(P)plays a pivotal role in the material-energy cycle of the biosphere,profoundly influencing the quality of water environments and the process of life succession.While traditional theories often consider the phosphorus cycle to be primarily sedimentary,with orthophosphate(P^(+Ⅴ))as the primary driver,this neglects the presence of inorganic reduced phosphorus(IRP)forms such as phosphine(P^(-Ⅲ)),hypophosphite(P^(+Ⅰ)),and phosphite(P^(+Ⅲ)),which have lower valences than^(+Ⅴ).This oversight results in a significant knowledge gap in our understanding of P cycling in water bodies.The aim of this paper is to summarize our current understanding of IRP's sources,compositions,detection methods,spatial and temporal distribution,transport and transformation processes,as well as its bioavailability.It is expected to enrich and improve the lake phosphorus cycle theory to provide key information and a scientific basis for lake water environmental protection and management.
