Abstract：The species composition,dominant species,abundance,biomass,biodiversity and communi-ty structure of polychaetes were analyzed based on the data collected from Yellow Sea in spring(April and May)of 2014.A total of 110 polychaete species in 67 genera,37 families,were collected.The mean abundance and mean biomass of polychaetes were 1362 inds./m2 and 6.92 g/m2,respectively,in spring.The Shannon-Wiener diversity index(H')was 3.94.The dominant species were Mediomastus californiensis,Ampharete acutifrons,Sternaspis scutate,Terebellides stromii and Sigambra bassi in the surveyed area.It was shown that the abundance of polychaetes was higher in the western part than in the central and eastern parts.The distribution of polychaetes mainly was affected by sediment type and water depth.
