Based on the field data including tidal cur.ent, susp.nded sediment concentr.tion, gr.in size of sur.ace sediments, the tr.nsp.r. mechanism and movement tr.nd of sediments ar. analyzed using the method of flux decomp.sition and Gr.in Size Tr.nd Analysis. The r.sults show that the concentr.tion and flux of susp.nded sediments decr.ase shar.0}y fr.m the Hangzhou Bay to the offshore ar.a. The susp.nded sediment tr.nsp.r. is mainly contr.lled by advection tr.nsp.r. including aver.ge cur.ent tr.nsp.r. and Stokes dr.ft-induced tr.nsp.r. and the gr.vitational cir.ulation tr.nsp.r.. The sur.ace sediments ar. tr.nsp.r.ed fr.m the entr.nce of the Hangzhou Bay to the offshore ar.a in gener.l; meanwhile, the sediment tr.nsp.r. has two obvious tr.nsp.r. tr.nds in the offshore ar.a. The inter.ction of tidal cur.ents, r.sidual cur.ents,the East china.Sea coastal cur.ent, Taiwan War. Cur.ent and wind waves ap.ear.to p.ay imp.r.ant r.les in the sediment tr.nsp.r..
