英文摘要	河口区大型底栖动物具有的重要群落特征往往可以反映群落所经历的环境污染。为更好地了解珠江河口区大型底栖动物群落结构,作者于2014年11月至2015年8月进行了4个季度的大型底栖动物调查,并利用PRIMER 6.0软件进行群落生物多样性指数计算、群落等级聚类(Cluster)和非度量多维标度排序(nMDS)分析。研究结果显示:珠江河口区共获得大型底栖动物52种,优势种包括光滑河篮蛤(Potamocorbulalaevis)、中国绿螂(Glaucomya chinensis)、焦河篮蛤(Potamocorbulaustulata)和羽须鳃沙蚕(Dendronerispinnaticirrus)。大型底栖动物年平均密度为269.3 ind./m~2,年平均生物量为129.61g/m~2。12个站次的丰富度指数(D)、均匀度指数(J’)和Shannon-Wiener多样性指数(H’)平均值分别为1.81±1.38、0.50±0.27和1.60±1.13。该结果显示除P01断面的秋季和冬季环境质量为优良外,其他站位在不同季度都显示出轻度到重度的污染。Cluster聚类分析和n MDS标序结果表明, P01断面与P02和P03断面群落相似度较低,与断面地理分布情况一致;P02断面和P03断面存在交叉聚集,群落相似度较高。结合环境因子结果可知,沉积物理化因子与群落分布特征相关性较大,其中最能解释珠江河口区群落多样性分布特征的环境因子为盐度和pH值。
中文摘要	The macrobenthic communities of estuaries are often indicative of important community traits,such as the environmental pollution a community may experience.To better understand the structure of Pearl River Estuary’s macrobenthic community,macrobenthic species were identified based on investigations carried out from November 2014 to August 2015,and biodiversity analyses were performed.More specifically,biodiversity index calculations,cluster analysis,and nMDS(non-metric MDS)analysis were performed used PRIMER 6.0 software.While 52 macrobenthic species were identified in the Pearl River estuary,the dominant species in this study area were Potamocorbula laevis,Glaucomya chinensis,Potamocorbula ustulata and Dendroneris pinnaticirrus.The annual mean density of macrobenthos in the Pearl River Estuary was 269.3 ind./m2 and the annual mean biomass was 129.61 g/m2.The mean values of richness index(D),evenness index(J')and Shannon-Wiener diversity index(H')of 12 samplings were 1.81±1.38、0.50±0.27 and 1.60±1.13,respectively.The results showed a range of environmental quality from clean to severe pollution,in which only P01 section indicated clean environmental quality in autumn and winter.Cluster and nMDS results revealed that low community similarity were observed among P01 section and P02 together with P03 sections,potentially due to the geographical distribution factors.Additionally,the P02 section and P03 section gathered crosswise with higher community similarity.Our results suggested the combination of environmental factors with physical and chemical sediment factors were significantly correlated with the distribution characteristics of communities.Also to note,water salinity and pH can help explain the biodiversity distribution pattern of the microbenthic community in the Pearl River Estuary.
