底棲動物
Marine benthos are characterized by narrow activity and special territory distribution and can be used to indicate the quality of water and the polluted condition of sediments, which plays an important part in the biologic indication of marine pollution.
海洋底棲動物活動性小、地區(qū)性強，可以較好地反映水質和底質的污染狀況，在海洋污染生物學指標中具有特別重要的意義。
底棲生物
This case study results shows up:1. The exploiting activity of Offshore Oil Field of Beibu Gulf has certain impact on the surroundings waters, obviously on the sediments and benthos within 500 m radius around the oil field.
本研究結果顯示：1．北部灣油田開發(fā)活動對油田周圍海域產(chǎn)生了一定程度的影響，尤其對油田周圍半徑500m范圍內沉積物和底棲生物的影響比較明顯。
