中文摘要:
      2006年8月在山东南部沿岸海域32个站位进行了大型底栖动物研究,共发现大型底栖动物182种,其中,多毛类92种,甲壳类42种,软体动物29种,棘皮动物9种,其他类群10种。研究海域大型底栖动物总平均丰度为2001 ind./m2,总平均生物量为15.92 g/m2。根据IRI指数,优势种前4种分别是寡鳃齿吻沙蚕(Nephtys oligobranchia)、中蚓虫(Mediomastus sp.)、独指虫(Aricidea fragilis)和巴氏钩毛虫(Sigambra bassi)。Shannon-Wiener多样性指数(H¢)为2.20~4.59,平均值为3.92;Margalef丰富度指数(d)为0.99~5.39,平均值为3.98;Pielou均匀度指数(J)为0.61~0.89,平均值为0.80。根据CLUSTER分析结果,在36%的相似性水平上可将研究站位划分为2个群落。多样性分析表明,研究海域底栖生态环境总体为清洁。Pearson相关性分析显示,大型底栖动物丰度和水深呈显著负相关(r=-0.38, P<0.05)。BIOENV分析表明,与群落结构关系最密切的环境因子组合是粉砂+水深+有机碳(r=0.46)。
英文摘要:
      The community of macrobenthos was investigated at 32 stations in the southern coastal waters nearby the Shandong Province in August 2006. A total of 182 species were identified, including 92 species of Polychaeta, 29 species of Mollusca, 42 species of Crustacea, 9 species of Echinodermata, and 10 species of minor phyla. Nine of the top ten dominant species (Nephtys oligobranchia, Mediomastus sp., Aricidea fragilis and Sigambra bassi, Leptomya minuta, Paralacydonia paradoxa, Sternaspis scutata, Eudorella pacifica, Lumbrinereis debilis, Prionospio sp.) were polychaetes. The average abundance of the macrobenthos was 2001 ind./m2, and the average biomass was 15.92 g/m2 in the investigated area. The value of Shannon-Wiener index (H¢) of macrobenthos was 2.20~4.59 with an average of 3.92. The value of Margalef’s richness index (d) was 0.99~5.39 with an average of 3.98. The value of Pielou's evenness index (J) was 0.61~0.89 with an average of 0.80. According to the results of CLUSTER analysis, the macrobenthos at the 32 stations could be clustered into two infaunal communities at 36% similarity, which were Mediomastus sp.-N. oligobranchia-Prionospio sp. Community (Community Ⅰ), and N. oligobranchia-A. fragilis-S. bassi Community (Community Ⅱ). The dissimilarity between Community Ⅰand CommunityⅡwas 77.21%. Analysis on Shannon-Wiener index (H¢) showed that all stations were unpolluted except for the 147th station, which suggested that the macrobenthic environment in the investigated area was generally clean. Pearson correlation analysis showed that the abundance and the depth of the water were significantly and negatively correlated (r=–0.38, P<0.05). BIOENV analysis indicated that the most crucial combination of environmental factors for the structure of community was silt + depth + organic carbon (r=0.46). Compared to the results of other previous reports, the average abundance value in our study was the highest. while the average biomass value was the lowest
