| 摘要: |
| 利用2008 年7 月3 日至25 日在青岛附近海域浒苔[Enteromorpha prolifera (Muell.) J. Ag]暴发期间进行的大型底栖动物定量分析资料, 研究了该海域大型底栖动物群落在物种组成、生物量和丰度以及物种多样性方面的动态变化, 以了解浒苔暴发对大型底栖动物的生态学影响。结果表明, 本项目调查共采集到大型底栖动物152 种, 其中优势类群是环节动物多毛类78 种, 占51.32%。在调查期间, 底栖动物的物种数量、平均栖息密度和生物量及物种多样性指数均发生较大的变化, 其中环节动物多毛类的变化尤其明显。ABC 曲线分析也表明, 胶州湾口附近取样站的底栖动物群落在当时已受到中等程度干扰, 其他某些站位在某次调查中也显示出一种大型底栖动物群落倾向于受到中等程度干扰的状况。 |

| Abstract: |
| Based on the material collected by five cruises from five sampling stations in the sea areas around Qingdao in July, 2008, we studied the ecological characteristics of the macrobenthic community during the upsurge of green seaweed Enteromorpha prolifera. The results showed that 152 macrobenthic species in total were found during the research, in which Polychaeta was the most abundant group with 78 species, amounting to 51.32% of all the species. The ABC analysis showed that the macrobenthic community at the inner side of the mouth of Jiaozhou Bay had been affected by the upsurge, and the macrobenthic communities out of the bay were also disturbed by the upsurge. |
