Under the different pH conditions, the migration and transformation behavior of each form of phosphorus released from the lake sediments into water body was studied by means of simulation. The results show that under alkalic condition or acidic condition, the temporal and spatial distribution of phosphorus in the water body changes with its releasing mechanism, and its migration and transformation behaviors are various. The change of pH value has no obvious effect on such transformation, but the total phosphorus in the water body has substantial effect on the concentration change of various forms of phosphorus.
