摘　　要：于2006年12月对胶州湾及邻近山东半岛南岸进行小型底栖动物调查。研究表明,小型底栖动物的平均丰度为(915.43±407.58)ind.10 cm-2,平均生物量为(1 007.56±422.71)μg.dwt.10 cm-2,平均生产力为(9 068.03±3 804.43)μg.dwt.10 cm-2.a-1。共鉴定出16个小型底栖动物类群。按丰度,自由生活海洋线虫占绝对优势,为总丰度的89.70%,其他优势类群依次为底栖桡足类、多毛类和双壳类;按生物量依次为多毛类38.49%,线虫32.60%,介形类10.31%,桡足类8.84%。The meiofauna was quantitatively investigated in Jiaozhou Bay and the southern coastal waters of the Shandong Peninsula in December, 2006.The mean abundance,biomass and productivity of meiofauna were(915.43±407.58) ind·10 cm-2,(1 007.56±422.71) μg·dwt·10 cm-2 and(9 068.03±3 804.43) μg·dwt·10 cm-2·a-1,respectively.A total of 16 meiofaunal groups were identified.Free-living marine nematods were the most dominant group in abundance in virtually all stations,accounting for 89.70%,followed by benthic copepods,polychaetes and bivalves;in terms of biomass,the dominant groups were polychaetes(38.49%),nematods(32.60%),ostracoda(10.31%),and benthic copepods(8.84%).
