%X The fluxes of dissolved nutrients at sediment-water interface were investigated at 4 stations in the HAB area of East China Sea in May 2001 and May 2002. The benthic fluxes of nutrients were determined by incubating the sediment core samples with bottom seawater bubbled with air or nitrogen. The transfer of nutrients was more active under anoxic condition. The fluxes of dissolved nutrients were generally high at the stations close to the coast. The sediment was the source of SiO 3 2-, which accounted for 6% of primary production. For DIN and PO 4 3-, the sediment was the sink. DIN and PO 4 3- adsorbed by sediment accounted for 5.9% and 67% of the riverine DIN and PO 4 3- inputs, respectively, and the inputs of SiO 3 2- accounted for 7.8%.
