| 摘要: |
| 利用 2000—2009 年 10 年间在胶州湾每年的春、夏、秋、冬(5、8、11、2 月)各季度月的海洋调查资料, 对胶州湾底栖动物的种类组成及变化进行了初步研究。 结果表明, 10 年间在胶州湾共采集到大型底栖动物 552 种, 其中环节动物门的多毛类动物 225 种, 软体动物 107 种, 甲壳类动物 150种, 棘皮动物 25 种, 其它门类动物 45 种。采集到底栖动物种数最多的年份是 2007 年(206 种), 最少的年份是 2005 年(159 种)。多毛类动物是胶州湾大型底栖动物的优势种。10 年间每年所采集到的种数相差不大, 门类组成变化较小, 优势种有所变化。 本文可为今后胶州湾海洋调查底栖动物的种类鉴定提供较详实的参考资料。 |

| Abstract: |
| Based on macrobenthic samples collected from the Jiaozhou Bay during 2000—2009, we report the composition of macrobenthic species and its changes over this ten year period. The results showed that a total of 552 species were found in this area, including 225 species of Polychata, 107 species of Mollusca, 150 species of Crustacea, 25 species of Echinodemata, 17 species of fish, 8 species of Coelenderata, and 20 species of other minor animal groups. The number of species was lowest in 2005 (159 species) and highest in 2007 (206 species). The changes in species number and their compositions were not distinct. Polychata was the dominant macrobenthic group in the bay, with most of the 12 dominant species. The dominant species had changes over the ten year period. |
