| 摘要: |
| [目的]为了解渤海大型底栖动物多样性现状,研究其物种多样性和分类多样性的分布格局。[方法]依据2008年8月和2009年6月两航次渤海大型底栖动物调查资料,对其物种多样性的辛普森优势度指数(λ)、香农-威纳多样性指数(H')、Margalef物种丰富度指数(d)、Pielou's均匀度指数(J')和分类多样性的分类多样性指数(Δ)、平均分类差异指数(Δ+)、分类差异变异指数(Λ+)以及各指数与环境因子的关系进行分析。[结果]两航次共鉴定出大型底栖动物(或分类实体)270种,隶属于206属,130科,39目,19纲,12门。各多样性指数平均值λ为0.05,H'为4.80、d为7.35、J'为0.93、Δ为83.84、Δ+为87.90、Λ+为343.88。各多样性指数与环境因子中的粉砂-粘土含量、沉积物中值粒径、有机质含量无显著相关性,而水深、盐度和温度等水层环境因子则对其影响较为明显。[结论]渤海海域总体动物多样性较高,其中渤海海域沿岸地区、辽东湾西部、莱州湾西北部等地受扰动和污染严重。将物种多样性和分类多样性结合分析,可以更好地反映群落多样性结构。水深、盐度和温度等水层环境对渤海大型底栖动物的影响要大于沉积环境的影响。 |

| Abstract: |
| [Objective] In order to reveal the current status of macrofaunal diversity and its relationship with environmental factors, spatial patterns of species diversity and taxonomic diversity were studied.[Methods] Based on the macrofauna samples collected in August 2008 and June 2009 in the Bohai Sea, species diversity indices including Simpson dominance index (λ), Shannon-Wiener diversity index (H'), Margalef species richness index (d) and Pielou's evenness index (J'), and taxonomic diversity indices including taxonomic diversity index (Δ), average taxonomic distinctness (Δ+) and variation in taxonomic distinctness (Λ+) were analyzed.Furthermore, the relationships between these indices diversity and environmental factors were estimated.[Results] A total of 270 species or taxa were recorded in the Bohai Sea, and they belong to 12 phyla, 19 classes, 39 orders, 130 families and 206 genera. The averages of λ, H', d, J', Δ, Δ+ and Λ+ were 0.05, 4.80, 7.35, 0.93, 83.84, 87.90 and 343.88, respectively.The macrofaunal diversity indices, like silt-clay percentage, median diameter and organic matter, were not significantly correlated with sediment environmental factors while they were significantly correlated with pelagic environmental factors, such as water depth, salinity, water temperature and so on.[Conclusion] As a whole, the macrofaunal diversity was high in the Bohai Sea, of which the coastal areas, western Liaodong Bay and northwestern Laizhou Bay were disturbed and under heavy pollution. Combining both species diversity and taxonomic diversity can reflect the macrofaunal diversity comprehensively. Water depth, salinity and water temperature were more important than sediment environmental factors in affecting macrofauna in the Bohai Sea. |
