| 摘要: |
| 采用功能群及多元统计方法, 对山东荣成俚岛湾牡蛎壳人工增殖礁礁区与毗连非礁区底质中多毛纲动物群落结构进行对比研究, 评估了牡蛎壳人工礁对多毛纲底栖动物群落结构的影响。结果表明, 人工礁区与非礁区共采集19科39种多毛纲动物, 按食性分为植食性、沉积食性和肉食性三大功能群。礁区肉食性多毛纲动物栖息密度高于非礁区, 可能与人工礁礁体底栖多毛纲动物引起的边缘效应有关。多维尺度分析MDS、相似度分析ANOSIM以及多因素方差分析(PERMANOVA)结果表明, 礁区同非礁区多毛纲动物群落结构差异不显著, 这可能与牡蛎壳人工礁单体体积较小, 对近底层水体及底质理化环境的影响较小有关。综上所述, 牡蛎壳人工礁在较小时间尺度内(1—2年)对底栖环境无显著影响。 |

| Abstract: |
| Polychaeta have been shown a good indicator to environmental changes. We investigated the functional group and community structure of Polychaeta in reef and non-reef area to study the ecological effects of artificial oyster shell reef. 19 families and 39 species of Polychaeta were sampled in two areas. The dominant species of Polychaeta communities were herbivore and deposit-feeders. The most abundance species in the two areas were Scoletoma longifolia, Chaetozone setosa, and Cirratulus filiformis. The abundance of carnivore species in reef area was higher than that in non-reef area, which might be resulted from the halo effects of oyster shell reef. The statistic results using multi-dimensional scaling (MDS), similarities multivariate analyses (ANOSIM), and PERMANOVA showed that the difference of Polychaeta communities in reef and non-reef areas was not significant, because the shell reef size was relatively small and slightly affected near-bottom water flow and sediment environment. The oyster shell reef had no significant effects on local benthic environment in a short time (1—2 year). |
