The ecology characterization of macrobenthic community from the intertidal zone of Dayudao Village, Shidao Town, Shandong Peninsula

Based on analysis of the benthic samples collected from August,2008 to May,2009(representing spring,summer,autumn and winter,respectively) in the intertidal zones of Dayudao Village,Shidao Town,Rongcheng City,Shandong Peninsula,the macrobenthic community and its seasonal changes were characterized in the present paper.The results showed that the mean abundances,biomasses and species numbers of macrobenthos in this intertidal zone were 397.7 ind/m2,99.874 g/m2 and 68 species,respectively.The mean abundances,biomasses and species numbers of the macrobenthos were different among four seasons,namely,the mean abundances: Winter SummerAutumnSpring,mean biomasses SummerWinterAutumnSpring,species numbers: Winter SummerAutumnSpring.The sequence of biodiversity indices(H′,D,J) of the three intertidal zones were as follows: H′,low tidal zone high tida1 zone medium tidal zone;D,low tidal zone medium tidal zone high tida1 zone;J,high tida1 zone low tidal zone medium tidal zone.The seasonal changes of three biodiversity indices were not significant.
