| 摘要: |
| 2007年9月至2008年5月在海州湾采集15个站点的底泥样品,对大型底栖动物丰度和生物量进行调查研究。共采集到38种大型底栖动物,其中多毛类环节动物14种,甲壳动物5种,软体动物14种,棘皮动物1种,鱼类3种,扁形动物1种。春季平均生物量为3.3g/m2,平均丰度为164个/m2; 秋季平均生物量为26.8g/m2,平均丰度为180个/m2。本次调查与1959～1960年和2000～2001年南黄海的调查结果相比较,生物量有所下降。 |

| The abundance and biomass of macrobenthos in Haizhou Bay |

| Abstract: |
| Macrobenthos harvested from 15 sites in Haizhou Bay during September 2007 and May 2008 were investigated. In total, 38 species were collected, including 14 species of Polychaeta, 5 species of Crustacea, 14 species of Mollusca, 1 species of Echinoderma, 3 species of Fishes and 1 species of Platyhelminthes. The average biomass was 3.3 g/m2, and the average abundance was 164 ind/m2 in spring. The average biomass was 26.8 g/m2, and the average abundance was 180 ind/m2 in autumn. The average biomass of macrobenthos in Haizhou Bay has decreased compared with the national comprehensive ocean investigation results during 1959～1960 and 2000～2001 in the Southern Yellow sea. |
