In the light of reasonable disposal and resource utilization of dredged polluted sediment，we point out the shortages in dredged sediment utilization，and introduce three resource utilization methods，i.e.，backfill soil，baking-free building material，and planting soil，on the basis of which，reasonable selection of resource utilization methods is analyzed quantitatively by discriminating the content of organic matter，heavy metal，salinity and lithologic character of dredged polluted sediment.Furthermore，the effectiveness of quantitative selection method is verified by enumerating two cases，i.e.baking-free brick production and planting soil production using Taihu and Baiyangdian sediment，respectively.The research result reveals that it is accessible to determine the resource utilization method of environmentally friendly dredging soil from the view of lithology，organic content，salt content.
