摘要

“大洋一号”调查船于2011年5—6月在南大西洋中脊14°S附近进行了7个站位的小型底栖生物采样。共鉴定出小型底栖生物10个类群。小型底栖生物平均丰度为(60.63±54.77) ind/10 cm²,平均干重生物量为(9.42±8.92) μg/10 cm²。线虫是其中的优势类群,丰度为(47.42±47.99)ind/10 cm²,占总丰度的78.21%,另外,肉鞭动物和桡足类分别占总丰度的16.63%和3.91%。生物量前3位的类群依次为桡足类、线虫和肉鞭动物。小型底栖生物密度随沉积物深度增加而减少,约73.55%的生物丰度分布在0～2 cm层内。个体大小方面,有75.32%的小型底栖生物粒径处于32～125 μm范围内。

Abstract

A study was carried out by “Dayang Yihao” from May 25 to June 17,2011. The meiofauna samples were collected from 7 stations in the south Mid-Atlantic Ridge. The results showed that 10 benthic groups were founded from the surveyed area. The average abundance and biomass of meiofauna were (60.63±54.77) ind/10 cm² and (9.42±8.92) μg/10 cm², respectively. Nematodes were present the great abundance (47.42±47.99) ind/10 cm²,accounting for 78.21% of total abundance of meiofauna in study area. Besides,Sarcomastigophora and Copepod were also found to be the dominant taxa, constituting 16.63% and 3.91% of total abundance of meiofauna,respectively. Copepod had the most biomass in the 10 benthic groups,followed by Nematoda and Sarcomastigophora. The analysis of vertical distribution has shown that the abundance of meiofauna decreased with the depth in the sediment. About 73.55% of meiofauna live in the top 0-2 cm layer. In terms of body size,the range of 32-125 μm accounted for 75.32% of meiofauna.
