| 中文摘要: |
| 2007年4月和10月,在山东日照临近海域进行了大型底栖动物春季和秋季两个航次的调查，对采集到的大型底栖动物进行分类鉴定。结果显示：1) 全海域共鉴定底栖动物141种，其中多毛类、甲壳动物、软体动物分别占总种数的38.30%、34.75%和17.73%，三者构成大型底栖动物的主要类群。2)大型底栖动物的总平均丰度为1 885 ind/m2，总平均生物量为39.82 g/m2。3)大型底栖动物种类多样性,春季高于秋季。4)优势种随季节变化不大，生物群落结构稳定性较好。 |
| 英文摘要: |
| Two surveys on macrobenthos along the coastal waters of Rizhao were carried out in April and October 2007, and all the collected samples were classified. A total of 141 species were identified in the two surveys and the number of Polychaete, Crustacea and Mollusca, which were the dominant species,accounted for 38.30%, 34.75% and 17.73% of the total number of species. The total mean abundance and biomass were 1 885 ind/m2 and 39.82 g/m2 at the 7 stations. Biodiversity of macrobenthos was higher in spring than that in autumn. Dominant species slightly changed in different seasons, and biological community structure was stable, except that station SR001 in spring and station SR003 and SR005 in autumn were disturbed moderately. |
