主　　题：Xiaoqing River Estuary Laizhou Bay macrobenthos community structure characteristics 

摘      要：The macrobenthic community of the Xiaoqing River Estuary and the adjacent sea waters was investigated in May and November 2008,August 2009,and May and September 2010,respectively.A total of 95 species of macrobenthos were identified in the five cruises and most of them were polychaetes(46.39%),mollusks(28.86%) and crustaceans(20.62%).The Shannon-Wiener index of macrobenthos was lower than 2 in 67% *** the stream channel,estuary and the coastal waters,the species of polychaetes reduced gradually,while the abundance increased at first and then *** abundance was the biggest at regions with salinity of 5 20 in the *** species and abundance of mollusks and crustaceans increased *** for seasonal distribution,the species,abundance and biomass were higher in spring and lower in summer and *** compared with Laizhou Bay and Yellow River Estuary,the species of macrobenthos appeared in the Xiaoqing River Estuary were much less,while the percentage of polychaetes was *** and biomass were higher in Xiaoqing River estuary,then consequently followed by Laizhou Bay and Yellow River *** dominant species in Xiaoqing River Estuary was polychaete,and Layzhou Bay *** community structure characteristics of macrobenthos in the Xiaoqing River Estuary revealed a significant pollution status in this region.
