摘要: 兴化湾大型底栖生物已鉴定有314种,平均生物量为36.60g/m2,平均栖息密度为162个/m2.按Bray-Curtis相似性指数和多维排序尺度可划分为4个群落.应用丰度生物量比较法(ABC)和种类个体几何级数显示群落结构相对稳定.Abstract: The species composition,quantity distribution and community structure are analyzed,All of 314 species of macrobenthos have been identified in the Xinghua Bay,Fujian,The average biomass is 36.60 g/m2,the inhabited density is 162 ind,/m2.There are four communities of macrobenthos in the Xinghua Bay which are divided according to Bray-Curtis similarity and multidimensional scaling ordination,The relatively stability of communities are shown based on abundance biomass comparison method and species individual geometric progression.
