山东半岛镆铘岛潮间带大型底栖动物群落特征

Based on the macrobenthos collected seasonally from three intertidal zones (the high, middle and low tidal zones) in Moye Island, Shandong Peninsula during January to October 2007, the characteristics of macrobenthos community were investigated in this paper. Ninety-two species were found in this area, including 22 Polychate species, 28 Mollusk species, 33 Crustacean species, 2 Echinoderm species and 6 species belonging to other groups. The average biomass and abundance were 81.74 g/m2 and 329.67 ind./m2, respectively. Mollusca were the dominant group to the total biomass, followed by Crustacea; Mollusca also provided most contribution to the total abundance, followed by Polychaeta. The Shannon-Weiner index was highest in the high tidal zone and lowest in the low tidal zone, and varied with seasons, autumn > spring > winter > summer.
