英文摘要 | In spring and summer 2011,the macro-and megabenthic fauna in two sections of the East China Sea were investigated using an Agassiz net trawl to detect the seasonal and spatial variations of benthic community characteristics and the relation to environmental variables.The total number of species increased slightly from spring(131 species)to summer(133)whereas the percentage of Mollusca decreased signifi cantly.The index of relative importance(IRI)indicated that the top fi ve important species changed completely from spring to summer.Species number,abundance and biomass in summer were signifi cantly higher than in spring,but no signifi cant dif ference was observed among areas(coastal,transitional and oceanic areas,divided basically from inshore to of fshore).Species richness(d),diversity(H′)and evenness(J′)showed no signifi cant seasonal or spatial variations.Cluster analysis and n MDS ordination identifi ed three benthic communities from inshore to of fshore,corresponding to the three areas.Analysis of Similarity(ANOSIM)indicated the overall signifi cant dif ference in community structure between seasons and among areas.K-dominance curves revealed the high intrinsic diversity in the off shore area.Canonical correspondence analysis showed that the coastal community was positively correlated to total nitrogen and total organic carbon in spring,but negatively in summer;oceanic community was positively correlated to total nitrogen and total organic carbon in both seasons.Species such as Coelorhynchus multispinulosus,Neobythites sivicola,Lepidotrigla alata,Solenocera melantho,Parapenaeus fi ssuroides,Oratosquilla gonypetes and Spiropagurus spiriger occurred exclusively in the of fshore oceanic area and their presence may refl ect the infl uence of the off shore Kuroshio Current. |
