摘要
于2006年12月对山东半岛南部近岸海域进行了37个站位的大型底栖动物调查。调查海域共发现大型底栖动物266种,大型底栖动物的总平均丰度和生物量分别为2 373ind./m^2和10.42g/m^2,丰度呈北部高、南部低的分布规律,生物量呈沿岸高、外围海域低的分布规律;调查海域IRI指数居于前10位的种中,多毛类8种,软体动物2种,显示了多毛类在调查海域的优势地位;多样性指数H’表明,调查海域除个别站位外底栖生态环境整体清洁;在23%相似性水平上,调查海域可划分为4个群落,群落呈明显地域性分布;沉积物类型显著影响调查海域大型底栖动物丰度分布。
The macrobenthic samples were taken in the southern coastal waters of the Shandong Peninsula in December,2006.A total of 266 species were indentified in survey area where the average abundance and biomass of macrobenthos were 2 373 ind./m^2 and 10.42 g/m^2,respectively.The distribution of abundance in the north were higher than in the south and biomass longshore were higher than peripheral waters in survey area.The top 10 IRI species including 8 Polychaetes and 2 Molluscs indicated that polychaetes were dominant in survey area.Shannon-Wiener diversity index(H')showed that the benthic environment were integral clean except several stations in survey area.At 23% similarity levels,4 distinct station groups could be clustered in different regions.The sediment characteristics obviously influenced the abundance pattern of macrobenthos in survey area.
