摘要
根据2006年3月同安湾12个调查站位所采集的大型底栖生物样品,对同安湾底栖生物组成和群落结构进行叙述和讨论.结果表明:同安湾大型底栖生物共有163种,其中多毛类、软体动物和甲壳动物为三大主要类群.海区大型底栖生物平均丰度为845 ind./m2,平均生物量是13.81 g/m2,鳄鱼屿附近海域丰度和生物量相对较低.根据Cluster聚类和MDS标序的结果,同安湾大型底栖生物可划分成3个群落,群落Ⅰ的多样性水平最高.同时,使用复合k-优势度曲线法对各个群落结构受扰动的程度进行分析,结果显示3个群落均出现一定扰动.
An analysis of macrobenthic species composition and community structure was conducted based on 12 sampling collected from March 2006 in Tong＇ an Bay. The results show that： 163 species were identified in the macrobenthos, among which Polychaeta, Mollusca and Crustacea constituted the main population of macrobenthos. The average abundance and biomass of macrobenthos were 845 ind./m^2 and 13.81 g/m^2 respectively in study area,and they are relatively low near the E＇yu island. There were three macrobenthic communities in Tong＇an Bay which were divided by CLUSTER and MDS analysis,among which community I ＇ biodiversity level was the highest. According to Abundance-Biomass Comparison analysis, certain disturbance were revealed in all the three communities.
