Characteristics of Macrobenthic Animal Communities in Northeastern Nearshore Area of Outside Bay of Qinzhou
摘要
Abstract
[Objective]The community structure on macrobenthic animals was analyzed,in north-eastern nearshore area of outside bay of Qinzhou,in order to determine whether the communi-ties were affected,and to find out the relationship between diversity indices of macrobenthos and environmental factors.[Methods]Trawl surveys were carried out in Jun.and Dec.2010.The survey data were analyzed by using the PIMER and SPSS software.[Results]148 species were collected altogether,including 57 species of Mollusca,42 species of Arthropod and 20 species of demersal fishes.[Conclution]The analysis showed that the macrobenthic communities can be divided into three groups in summer,and two groups in winter.The bio-diversity was better in summer than in winter.The abundance-biomass curve analysis showed that a few of the sta-tion’s macrobenthos were affected modestly,and few was affected seriously.Pearson correla-tion analysis showed that biomass,abundance and number of species all had significant negative correlation with oil concentration in sediment in summer;the abundance also had significant positive correlation with the median diameter of sediment;Shannon-Wiener index had significant positive correlation with the percentage of clay in sediment.In winter,number of species had sig-nificant positive correlation with salinity,pH and DO,and also had significant negative correlation with oil concentration in water.The abundance index had significant positive correlation with DO in water.关键词
