于2007年1月至2007年10月间冬、春、夏、秋4个季度月,对位于山东荣成的镆铘岛潮间带的高潮带、中潮带和低潮带进行大型底栖动物生态调查,根据所获得的样品,对该潮间带不同潮区大型底栖动物的种类组成、平均密度、平均生物量及物种多样性进行了分析.本次调查共采到大型底栖动物92种,其中多毛类环节动物11科22种,软体动物17科28种,甲壳动物18科33种,棘皮动物2科2种,扁形动物1种,腔肠动物2种,鱼类3种;平均栖息密度为329.67个/m2,软体动物贡献最大,其次为甲壳动物;平均生物量为81.74 g/m2,软体动物贡献最大,其次为多毛类环节动物.镆铘岛潮间带多样性指数H'垂直变化规律为高潮带>中潮带>低潮带,季节变化规律为秋季>春季>冬季>夏季.

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 macroben-thos 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.
