The results showed that pH of the irradiated sediment core is higher than the unsterilized one,and microorganisms could have an effect on the pH of sediments.All the four sediments are in the strong reductive environment at the depth of 7~30 cm,and the values of Eh are quite closer,the main factor that affect the redox environment may be the compaction of the sediment.All the sediments had a cumulation of phosphorus at the surface layer,and the total phosphorus of the sediments at the depth of 4~10 cm are lower than the average.It is indicated that phosphorus had been redistributed at the suface layer.
