中文摘要:
      根据2017年7月胶州湾海域的大型底栖动物调查数据,应用聚类分析、生物多样性和Multivariate-AZTI’s Marine Biotic Index (M-AMBI)等方法分析了大型底栖动物的生态学特征,评估了胶州湾底栖生态系统的健康状况。结果显示,调查海域共采集到大型底栖动物64种,其中多毛类25种,甲壳动物23种,软体动物9种,棘皮动物和其他类群各4种;该海域大型底栖动物生物量和丰度的平均值分别为70.0 g/m2 和132 ind./m2,菲律宾蛤仔(Ruditapes philippinarum)、寡鳃齿吻沙蚕(Nephthys oligobranchia)和纽虫(Nemertinea)是优势种。物种多样性指数(H^')为0.69~3.77,平均值为2.35,丰富度指数(d)为0.67~3.12,平均值为1.56,Pielou均匀度指数(J)为0.25~1.00,平均值为0.81。多样性AMBI指数(M-AMBI)为0.26~0.60,平均值为0.44。根据CLUSTER分析结果,在15%相似水平上可将研究站位划分为3个群落,聚类结果与菲律宾蛤仔养殖密切相关。大型底栖动物群落的多样性指数和M-AMBI指数分析显示胶州湾海域底栖生态系统受到中等程度的干扰。
英文摘要:
      Based on the survey data in the Jiaozhou Bay in July 2017, the ecological characteristics of macrobenthos were analyzed using Clustering analysis, biodiversity and M-AMBI methods. A total of 64 species were identified, including 25 species of Polychata, 23 species of Crustaceans, 9 species of Mollusks, 4 species belong to other benthic groups and Echinoderms. The average biomass and the abundance were 33.67 g/m2 and 136 ind./m2, respectively. There were three dominant species including Ruditapes philippinarum、Nephthys oligobranchia and Nemertinea. The ranges of Margalef species richness index, Shannon-Wiener diversity index, Pielou’s evenness index and multivariate-AMBI were 0.69~3.77, 0.67~3.12, 0.25~1.00 and 0.26~0.60, respectively. According to the results of CLUSTER analysis, the macrobenthos at the 15 stations could be clustered into three infaunal communities at 15% similarity. Clustering results were related to Philippine clam farming . Shannon-Wiener Index (H′) and multivariate AMBI(M-AMBI) analysis showed that the macrobenthic community tend to be disturbed moderately.
