摘要: 对福建海岛潮间带大型底栖生物共鉴定862种,其中动物为734种,藻类为128种.对11个主要海岛的潮间带生物群落测定Jaccard群落系数,应用加权均值联结法聚类分析及极坐标排序分析,海岛潮间带生物群落可分为3个类型:(1)开敞海域群落,宏观上分布于地处远岸水域的海岛或近岸凸出部、开阔部水域的海岛;(2)近岸港湾群落,分布于近岸或港湾的海岛;(3)河口群落,分布于河口区的海岛.群落种类组成和海岛所在地理位置及其生境密切相关.盐度和水扰动程度是影响群落分布的主要因子Abstract: A total of 862 biobenthic species are found in the intertidal zone Fujian islands,which belong to 734 species of animals,128 species of algae.Jaccard's similarity index of species is measured,and the distribution of the benthic community is studied using hierarchical clustering(WPGMA) and polarordination.The result indicates that the benthic communities are divided into three classifications:the estuary type,harbour type and wide sea type of the community.The distribution of the benthic community is related to the island location and its environment.The salinity and motive power of the water are major factors which influence the community.
