%X The concentrations of total phosphorus (TP), bioavailable phosphorus (BAP) and their seasonal changes in the surface sediments (0-10 cm) from three different regions of northeast of Taihu Lake were investigated. The results show that the concentrations of TP and BAP in the sediment are coincided with the corresponding trophic level of the overlying water. The concentrations of TP and BAP in the sediments varied widely not only between sampling sites but also between seasons. There is a significant correlation between BAP and TP in surface sediments, and their regression analysis equation varies with seasons. It is suggested to evaluate potential phosphorus-release risk of the sediment based on the TP concentration of the corresponding seasons.
