摘要
文章通过分析浙江大渔山岛潮间带大型底栖动物的物种组成、数量分布和生物多样性等群落结构特征来了解周围海域的水质状况。本次大渔山岛海域潮间带调查采获的大型底栖动物标本共有35种,其中软体动物21种,节肢动物9种,脊索动物与腔肠动物各2种,环节动物仅1种。且该海域潮间带大型底栖动物的平均生物量为1027.33 g/m2,平均丰度为1404 ind./m2。在各类群底栖动物中,软体动物的平均生物量及丰富都为第一。大渔山岛潮间带大型底栖动物的多样性指数、丰富度指数和均匀度指数的分布范围分别在0.193～2.101、0.268～1.744和0.073～2.007,平均值分别为1.140±1.084、1.080±0.696和0.780±0.886。
The community structures of the intertidal macrobenthic fauna in Dayushan island,Zhejiang,including species composition,quantity distribution and biodiversity,were analyzed in the study.The investigation in the study found 35 species,including 1 species of Annelida,2 species of Chordata,2 species of coelenterate,9 species of Arthropoda and 21 species of Mollusca.The average biomass and density in all stations were 1027.33 g/m2 and 1404 ind.m-2,respectively.The mollusca were the first in biomass and density among all macrobenthic fauna.The value of Shannon-Weaner index,Margalef＇s species richness index and Pielou＇s evenness index were 0.193～2.101,0.268～1.744 and 0.073～2.007,and their averages were 1.140±1.084,1.080±0.696 and 0.780±0.886,respectively.There was significant difference between the results in the study and in the similar experiments.The Abundance/Biomass curves of the intertidal zone of Dayushan island had part of the cross.
