The release of phosphorus in lake sediment is the key to prevent the management of eutrophication lakes.Therefore,it is very important to understand the influencing factors and mechanism of the phosphorus release process in lake eutrophication control.The fraction,classification and bioavailability of phosphorus were summarized,the environmental factors affecting the release of internal phosphorus,and the problems existing in the release process of internal phosphorus in sediment and the mechanism study were analyzed.Furthermore,the future research directions for...
