摘要
本文为作者在研究国内外有关土壤磷素研究文献的基础上,结合自已正进行的"小流域磷的环境动态变化研究"基金课题综述而成。所述内容中,重点在二、三两部分,其中第三部分中的当前磷索研究的现状,侧重于机理方面的研究、注重于磷肥—生物产量相关性问题的研究、注重其与不同介质中的生物地球化学循环方面的研究。基于磷素在环境中日益显示的重要性与当前磷素研究中展现的迹象,预示:研究磷于土壤、水体、生物体等多介质中的形态、转化、迁移、地域分异及其输入输出量等,必将成为今后磷素研究中的主要趋向。
The paper is formulated on the basis of examination of existing literatune on the phos- phourus in soil,connecting with the result of ourself research project on'environmental regime variation of phosphorus in a small basin'.The paper consists of three parts with an emphasis on recent status of study on phosphorus in soil,i.e.on the study of mechanism for attitude of phosphorus in soil in third part and a highlight on the problem of phosphate fertil- izer-biomass production relation and biogeochemical cycle in different media.The increas- ing importance of phosphorus in environment and the evidence obtained in the recent study on phosphorus indicate the research on the form,transition,migration,geographical differ- entiation and budget of phosphorus in soil,water bady,biomass,and the media becomes a main tendency to study on phosphorus.
