摘　　要：胶体是磷素在环境中迁移转化的重要载体,土壤胶体磷对磷素生物地球化学循环具有重要作用,其活化迁移对土壤、水环境具有十分重要的影响。本文介绍了国内外土壤胶体磷的分类、分离和分析技术。重点阐述了土壤胶体磷活化、土壤基础理化性质(矿物组成、其他胶体元素、土壤孔隙结构、pH、氧化还原电位)、肥料及土壤改良剂应用对土壤胶体磷环境效应的影响。并针对目前土壤胶体磷流失存在的问题,提出相关对策及展望,以期为后续胶体磷研究和胶体磷污染的治理提供参考。Colloid is an important carrier of phosphorus migration and transformation in the environment.Soil colloidal phosphorus plays an important role in the biogeochemical cycle of phosphorus,and its activation and migration impact the soil and water envi-ronment.This paper introduces the classification of colloidal phosphorus,separation and analysis techniques;and elaborates the effects of colloidal phosphorus activation,soil basic physical and chemical properties including mineral composition,other colloidal elements,soil pore structure,pH,and redox potential,the use of fertilizers and soil conditioners on the environment in the latest research.For the current problems such as soil colloidal phosphorus loss,relevant countermeasures and prospects are proposed.This review may provide reference for future colloidal phosphorus research and colloidal phosphorus pollution control.
