Based on the macrobenthos materials samples collected in August 2009, October 2009, May 2010 and August 2010 in the Laizhou Bay, the present study analyzed species composition, abundance, biomass, community structure and compared with historical data of macrobenthos. The results suggested that 272 species of macrobenthos were identified in the research region, including 122 species of Polychaetea, 64 of Crustacea, 46 of Mullusca, 18 of Echinodermata, 9 of Pisces and 13 of other groups. The total average abundance was (1102.56±216.32) ind./m2, average biomass was (28.16±8.45) g/m2, Polychaetes were the most dominant groups in the abundance and Mollusks were dominant in the biomass. Regarding the spatial influence on macrobenthos, low values of abundance and biomass usually appeared in stations outside of the Huanghe River Estuary in the west of the bay, but high values occurred in the central of Bohai Sea. Regarding the temporal influence on macrobenthos, significant seasonal variations in the abundance and biomass were observed. The dominant species were distinct, the relative important species were Sternaspis sculata, Glycinde gurjanovae and Alvenius ojianus. Compared with the historical data, the species composition and dominant species had showed an obvious miniaturization trend.
