| 中文摘要: |
| 根据2012年9月对山东烟台辛安河口海域大型底栖动物调查资料，采用优势度指数、物种多样性指数、Cluster聚类和MDS排序、AMBI和M-AMBI等方法，结合单因子标准指数等非生物因素指标研究该海域底栖群落结构和生态状况。调查结果表明，水体无机氮和活性磷酸盐属于一类或二类海水水质标准，但调查海域溶解氧和pH均属于或超出四类海水水质标准，说明调查海域受到海洋酸化和缺氧的干扰。该海域共采集大型底栖动物62种，总平均丰度为577.50 ind./m2，总平均生物量为6.01g/m2，多毛动物是主要优势类群。污染指示种小头虫在Y1站位大量出现，结合环境数据分析表明该处底栖环境受到海洋酸化和缺氧的严重干扰。与2009-2011年历史数据比较，辛安河口及其邻近海域的底栖生物群落状况变化不大。AMBI和M-AMBI评价结果与环境因子评价较一致，该海域底栖生态环境受到轻度干扰，环境质量介于较差到高等之间。海洋酸化和缺氧对底栖生物群落结构产生影响，尤其是Y1，Y2和Y5站位，底栖环境评价结果均较差。 |

| To understand the ecological status and macrobenthic assemblages of the Xin'an River Estuary and its adjacent waters, a survey was conducted for environmental variables and macrobenthic assemblage structure in September 2012 (Yantai, China). Several methods are adopted in the data analysis process:dominance index, diversity indices, cluster analysis, non-metric multi-dimentional scaling ordination, AMBI and M-AMBI. The dissolved inorganic nitrogen and soluble reactive phosphorus of six out of eight sampling stations were in a good condition with low concentration. The average value of DO ((2.89±0.60) mg/L) and pH (4.28±0.43) indicated that the research area faced with the risk of ocean acidification and underlying hypoxia. A total of 62 species were identified, of which the dominant species group was polychaetes. The average abundance and biomass was 577.50 ind./m2 and 6.01 g/m2, respectively. Compared with historical data, the macrobenthic assemblage structure at waters around the Xin'an River Estuary was in a relatively stable status from 2009 to 2012. Contaminant indicator species Capitella capitata appeared at Sta. Y1, indicating the animals here suffered from hypoxia and acidification. AMBI and M-AMBI results showed that most sampling stations were slightly disturbed, which were coincided with the abiotic measurement on evaluating the health conditions. Macrobenthic communities suffered pressures from ocean acidification and hypoxia at the research waters, particularly those at Stas Y1, Y2 and Y5, which displays negative results in benthic health evaluation. |
