| 摘 要： | 渤海1998年9月航次的调查结果.小型底栖生物总平均丰度为(8688±5097)个/m2,底栖桡足类居第2位,平均丰度为(663±569)个/m2,占总数量的76%.根据77种底栖桡足类丰度所做的聚类和标序分析将渤海20个站位划分为4个组合.根据11种环境因子数据所做的聚类和主成分分析将研究海域划分为两个生境、4个亚区.对研究海域进行的分区与自然分区是基本一致的.支配研究海域底栖桡足类群落结构的主要环境因子是水深和沉积物粒度.

| Abstract: | The benthic meiofauna was quantitatively investigated at 20 stations in the Bohai Sea in September 1998.Mean meiofaunal abundance amounts to(868.8±509.7) ind/m2.Benthic copepods are the second in overall abundance,constituting 7.6% of the total meiofauna,with the mean abundance of(66.3±56.9) ind/m2.The cluster or dination and PCA analysis of 11 environmental variables show there are two distinctly different habitats in the Bohai Sea,these two habitats are divided into four sub-areas further.According to the cluster and MDS analysis of 77 benthic copepods species,four groups are divided,these areas are well coincident with natural zone.The major factors which affect the community structure of benthic copepods are depth and grain size of sediment. |
