Abundance and Biomass Characteristics of Intertidal Macrobenthic Community in Huiquan Bay

Based on macrobenthos survey carried out on different sections in four seasons form year 2009 to 2010 in the intertidal zone in Huiquan Bay,macrobenthos abundance and biomass were studied.The results show that the abundance and biomass of macrobenthos is a continuous decrease from spring to winter,but no significant change happens to spatial variation in same season.As to space,the changes in latitude and longitude of intertidal macrobenthic habitats in Huiquan Bay are not that large.Environment of flour is anther important factor that effects the distribution of macrobenthos.In different types of intertidal macrobenthic habitats,biomass and abundance are quite different.And the distribution of benthic communities is closely related with the sedimentary types.
