摘　　要：胶体在土壤磷素迁移中起重要作用.土壤胶体磷活化迁移对土壤磷库的变化和周围水环境质量产生影响.本文介绍了土壤胶体磷研究的相关进展,探讨了土壤理化性质、施肥、降雨、土壤改良剂等因素对胶体磷在土壤赋存迁移中的影响,分析了流场分离、电镜能谱、同步辐射X光近边吸收结构光谱和核磁共振等技术在胶体磷研究中的应用,以及降低胶体磷流失的方法,以期为胶体磷在土壤中赋存变化和迁移机制的研究提供重要信息.Colloids play a key role in the transference process of phosphorus （P） in soil. Activation and transference of soil colloidal phosphorus have great effect on soil P pool and the surrounding water quality. This paper summarized the current studies on soil colloidal P, discussing the effects of the various factors （e.g., soil physical and chemical properties, fertilization, rainfall and soil amendments） on the transference of soil colloidal P. Some advanced analysis technologies （e. g., flow field-flow fractionation, transmission electron microscope-energy dispersive X-ray spectrometer, X-ray absorption near-edge structure and nuclear magnetic resonance） and methods of reducing soil colloidal P were also involved. This review would provide important information on the mechanism of soil colloidal P transference.
