摘　　要：2011年12月—2013年1月对南韭山周围海域15个站位进行了大型底栖动物分布状况调查,共获得大型底栖动物59种,其中甲壳类20种,鱼类14种,软体动物11种,腔肠动物6种,其他类动物8种。相比于国内其他海域,数量处于较低水平。从平面布局上来看,种数分布呈自北向南和由近岸(西部)向外海(东部)逐渐增多的趋势。各季节出现种类,夏季34种,春季28种,秋季27种,冬季为19种。优势种及特征种年均更替率分别是78.75%与82.78%,表明南韭山海域大型底栖动物种类组成和群落结构季节更替显著。同2005—2006年相比,优势种组成变化较大,优势种数量有所增加,且个别种类优势度较高,表明南韭山海域大型底栖动物的群落结构发生了较大程度的变化。Investigations on the distribution of macrobenthos were made in 15 stations in waters around Nanjiushan Island during December 2011-January 2013.There were 59 species of macrobenthos, including 20 species of crustaceans, 14 species of fishes, 11 species of mollusks, 6 species of coelenterates, and 8 of other species, which were less than those in other domestic waters in quantity aspect. In general, the species gradually increased from shores （the west） to seas （the east）. Beside, the number of species in each season was given as follows： 34 species in summer, 28 species in spring, 27 species in autumn and 19 species in winter. The turnovers of dominant species and character species were 78.75% and 82.78% respectively, suggesting that the substitution of species and communities were significant in the NanJiushan Island waters. Moreover, the composition of dominant species changed greatly; the quantity of dominant ones increased and dominance of a few species was higher than others compared with 2005 to 2006, which implied the macrobenthic community structure had undergone significant changes in waters around Nanjiushan Island.
