汇泉湾潮间带大型底栖动物群落结构特征

Intertidal Macrobenthic Community Structural Features in Huiquan Bay

文章根据2009—2010年四个季度在汇泉湾潮间带开展的大型底栖动物调查,对不同季节不同断面的大型底栖动物的种类组成、群落结构作了分析。经鉴定汇泉湾潮间带大型底栖动物共有92种,包括软体类39种,多毛类29种,甲壳类15种,鱼类4种,棘皮类3种,还有腔肠和纽虫各1种。优势种是短滨螺Littorina(L)brevicula(Philippi)。均匀度跟总个体数具有一定的负相关关系。MDS排序结果与群落分布聚类分析结果基本一致。

Based on the data collected from the 15 sampling stations in four seasons from 2009 to 2010. the characters of macrobenthic community of the Huiquan Bay is approached The results show that 92 species were found in this area, including 29 species of Polychaeta, 15 of Crustacea, 39 of Mollusca and 3 of Echinodermata; the dominant species are Littorlna （L） brevlcula （Philippi） , Batillaria cumingi and Venempis Philippinaram. The results of CLUSTER and MDS analysis show that the structure of the macrobenthic communi- ties in the 15 stations of each season are not very unified.
