n.底生生物；海底的動(dòng)植物群

The molluscs were the first in biomass and density of the benthos. 全年各類(lèi)群生物中，平均生物量及棲息密度都以軟體動(dòng)物居首位。

Coastal zones are important habitats to fauna, having a primary production for offering such as benthos and sessile organisms. 摘要沿岸海域一直是生物重要的棲地，并且提供像底棲生物或附著生物相當(dāng)高的基礎(chǔ)生產(chǎn)。

The result indicates that benthos is affected by dredging activity but the extent of the impact is limited. 結(jié)果表明:疏浚工程影響著底棲動(dòng)物的生存,但其影響范圍是局部的。

In 1986 and 1988 the authors sampled macrofauna benthos and investigated the distribution of biomass and density. 作者于1986年和1988年在連云港海域進(jìn)行了底棲動(dòng)物采樣,調(diào)查得出了生物量和棲息密度的分布概況。
