中文摘要:
      根据2017年渤海海域47个站位大型底栖动物的调查资料,对该海域大型底栖动物进行了群落特征分析。调查共采集到大型底栖动物107种,研究海域大型底栖动物的平均密度为82 个/m2。优势种类分别为彩虹明樱蛤、不倒翁虫、长叶索沙蚕。聚类结果显示,渤海海域大致可按地理位置分为4个群落。与历史数据的对比显示,传统的较大个体的底栖种类,如棘皮动物、双壳类,已经被更小个体的多毛类、软体动物所取代,底栖动物的种类结构表现出了小型化的特征,这与近年来渤海海域底栖动物研究结果一致。研究表明,近年来受人类活动影响,渤海海域大型底栖动物群落结构已经发生了变化。
英文摘要:
      The community of Macrozoobenthos was investigated at 47 stations at the Bohai Sea in summer 2017. A total of 107 Macrozoobenthos species were collected, the average abundance of macrofauna was 82 ind/m2. The dominant species were Moerella iribescens,Sternaspis sculata and Lumbrineris longiforlia. The hierarchical clustering of between groups linkage showed that the Macrozoobenthos community could be divided into 4 groups, which were closely related to the geographical position. It is noted that the dominant species showed a miniaturization trend, while the traditionally dominantsized species, present study such as echinoderms and bivalves, were replaced by small sized polychaetes and mollusks that is similar to research results at Bohai Sea in recent years. The study showed that the Bohai Sea was affected by human activities in recent years, resulting in the changes of macrofauna community structure.
