Abstract

Two surveys on macrobenthos along the coastal waters of Rizhao were carried out in April and October 2007,and all the collected samples were classified.A total of 141species were identified in the two surveys and the number of Polychaete,Crustacea and Mollusca,which were the dominant species,accounted for 38.30%,34.75% and 17.73% of the total number of species.The total mean abundance and biomass were 1 885ind/m2 and 39.82g/m2 at the 7stations.Biodiversity of macrobenthos was higher in spring than that in autumn.Dominant species slightly changed in different seasons,and biological community structure was stable,except that station SR001in spring and station SR003and SR005in autumn were disturbed moderately.
