摘　　要：Phosphorus(P)is the main limiting factor in eutrophication.Sediment P can be released decades after its accumulation.Lake restoration requires the reduction of internal sediment P loading.Although we tried to provide a comprehensive summary of the state-of-the-art sediment P control technologies,our analyses in this review are focused on the mechanisms,control effects,and application conditions of different in-situ technologies including physical control,chemical control,ecological remediation,and combined control technology.The design principles,feasibility,operation parameters,and pros&cons of these technologies are analyzed and compared.More efforts are needed to improve in-situ sediment P control technologies so as to enhance the interaction between materials and plant communities and promote the adsorption and fixation of active P in sediments.The control materials for internal sediment P loading need to be further studied in terms of their functional properties,pre-evaluation of the P control effect,and engineering applications.
