中文摘要: 【目的】分析芝罘岛附近污水排放对该海域大型底栖动物群落结构的影响,为近岸海区生物多样性保护的可持续和海洋环境生态监测利用提供科学依据。【方法】于2012年9月在芝罘岛附近海域设置10个站位对大型底栖动物群落进行调查和分析。采用生物统计软件PRIMER6.0计算Shannon-Wiener多样性指数(H′)、Margalef物种丰富度指数(D′)和Pielou物种均匀度指数(J′),并进行等级聚类(CLUSTER)、MDS标序及ABC曲线分析。【结果】共鉴定出大型底栖动物63种,其中多毛类35种,软体动物13种,甲壳动物11种,棘皮动物3种,其他类群生物1种,优势类群为多毛类。总平均生物量为8....
英文摘要: 【 Objective】 Analyzing the impacts from the sewage discharge on the macrobenthic community provides scientific basis for sustain-able development of biodiversity conservation in coastal areas and marine environmental monito-ring. 【 Methods】 A survey was carried out in Sep-tember 2012 on 10 sampling stations at the wa-ter areas near to Zhifu Island, offshore area of Yantai, Shandong province. Community charac-ters , three biodiversity indices, CLUSTER, non-metric multi-dimensional scaling (MDS) ordina-tion analysis, abundance and biomass curves (ABC) analysis were calculated and analyzed by software PRIMER 6.0.【 Results】 A total of 63 macrobenthic species were identified,including 35 species of Polychaetes, 13 species of Mollus- can,11 species of Crustacean,3 species of the Echinoderm,one species of other groups,of which the dominant group was Polychaetes. The average biomass and abundance was 8. 30 g/m^2 and 618. 67 ind. /m^2 ,respectively,of which Molluscan species contributed most to biomass and Pol-ychaetes contributed most to abundance. Three biodiversity indices, Shannon-Wiener index, Richness index and Evenness index,were 3. 173 ± 0. 102,5. 469 ± 0. 417 and 0. 965 ± 0. 007,re-spectively. Pearson correlation analysis showed that Evenness index was significantly positive related to salinity. However, the Shannon-Wiener index and Richness index were not signifi-cantly related to the 12 environmental variables. CLUSTER and MDS analysis showed that macrobenthic assemblages could be divided into three sub-groups based on 60% similarity and significant difference was found between different sub-groups. The species composition of sta-tion Z2 nearest to the sewage discharge point was dominated by polychaetes and it showed a miniaturization trend.【 Conclusion】 The environmental variables such as water depth, dissolved oxygen,and TN influenced the spatial distribution of macrobenthos, and they were significantly related to the biomass and abundance.
