| 英文摘要 | 为摸清辽宁獐子岛潮间带及近岸海区的大型底栖动物的分布现状和群落受扰动情况,作者于2011年11月中旬在马牙滩潮间带和近岸海区采集大型底栖动物,采用优势度指数、Shannon-Wiener多样性指数、Margalef丰富度指数、Pielou均匀度指数,Bray-Curtis相似性聚类分析、MDS标序和ABC曲线等方法,分析该区域内大型底栖动物群落的生态学特点。结果表明,在潮间带共鉴定大型底栖动物39种,优势类群为多毛类、甲壳类和软体类;优势种均为多毛类,即小头虫(Capitella capitata)、多美沙蚕(Lycastopsis augenari)、仙居虫(Naineris laeviga... |
| 中文摘要 | We completed a quantitative investigation of the macrobenthic community in the intertidal zone and offshore areas of Zhangzi Island in November 2011 to identify the distribution and potential anthropogenic impacts on this aquatic community. Four biodiversity indices, Bray-Curtis similarity, MDS ordination analyses, and ABC curves were used in the present work to analyze the community structure. We identified 39 total macrobenthic species in the intertidal zone of Maya Beach, of which the most dominant groups were the Polychaeta, followed by Crustacea, and Mollusca. We found four dominant species belonging to Polychaeta, including Capitella capitata, Lycastopsis augenari, Naineris laevigata, and Lumbrineris latreilli. Average biomass of the intertidal zone was 25.76 ± 41.08 g/m~2, of which Mollusca contributed most. Average density was 315.11 ± 160.73 ind./m~2, of which the Polychaeta contributed most. The average value of three biodiversity indices were relatively low (Richness index 1.17 ± 0.89, Evenness index 0.74 ± 0.17 and Shannon-Wiener index 1.80 ± 1.09). We identified 40 species in the offshore areas, of which the most dominant group was Polychaeta, followed by Crustacea, Mollusca and Echinodermata. We also identified five dominant species in offshore areas, including Ophiopholis mirabilis, Amphioplus japonicus, Lumbrineris latreilli, Echinocardium cordatum, and Ophiura sarsiivadicola. The average value of biomass and density was higher in the offshore areas compared to that of intertidal zone, with 218.86 ± 152.24 g/m~2 and 700.00 ± 471.51 ind./m~2, respectively. The average value of Richness index was 1.40 ± 0.60, Evenness index 0.64 ± 0.19, and Shannon-Wiener index 2.04 ± 0.78. MDS ordination analysis showed that community structure was significantly different within the intertidal zone and the offshore areas. Lastly, the macrobenthos fauna in intertidal zone were impacted by a moderate anthropogenic disturbance, whereas the fauna in offshore areas was slightly disturbed. |
