| 中文摘要: |
| 分析了浙江六横岛潮间带大型底栖动物的种类组成、数量分布和多样性指数等群落特征。３个断面采获的大型底栖动物共有１９种，其中软体动物１０种，节肢动物６种，脊索动物２种，环节动物１种；总平均生物量为（４７０．７７±３１４．３２）ｇ／ｍ２，总平均密度为（４８０±２４８）个／ｍ２。在各类底栖动物中，平均生物量及密度都以软体动物居首位。大型底栖动物的Ｓｈａｎｎｏｎ－Ｗｉｅｎｅｒ多样性指数、Ｍａｒｇａｌｅｆ丰富度指数和Ｐｉｅｌｏｕ均匀度指数分别为１.９７～２.１４、１.４５～１.６７和０.８３～０.９５，平均值分别为（２．０６±０．０８）、（１．５３±０．１２）和（０．９０±０．０６）。ＡＢＣ曲线分析表明，底栖动物群落已受到一定程度的污染扰动。 |
| 英文摘要: |
| The community character of the muddy intertidal macrobenthic fauna in Liuheng island of Zhejiang province，such as species composition，quantity distribution and biodiversity，were analyzed in this study. The results indicated that there were 19 species，including 10 species of Mollusca，6 species of Arthropoda，2 species of Chordata and 1 species of Annelida. The average biomass and density in all stations were (470.77 ±314.32)g/m2 and( 480±248)ind./m2，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 were1.97-2.14, 1.45-1. 67 and 0. 83-0. 95，and the average was ( 2. 06 ±0. 08，(1. 53± 0. 12 ) and (0. 90±0. 06)，respectively. The Abundance/Biomass curves of Liuheng island showed that the marcobenthic fauna communities were partly disturbed by all kinds of pollution.
