嵊泗列岛;潮间带;群落结构;种类多样性
摘  要:
用Shannon-Wiever多样性指数、Pielous种类均匀度、Margalef种类丰度、McNaushton优势度4个测定群落种类多样性指标进行数值分析.结果表明,嵊泗列岛从近岸到外海.H’(S)、J、d值呈现逐渐增加的趋势.而D值则有逐渐减小的趋势;各断面多样性指数H’(S)以春、秋季较高,J值则基本上以春、冬季稍高,d值则随断面的不同有差异,D值基本上以夏、秋季为高用Whiftaker和Fairbanks群落系数计算公式及Bray-Curtis群落相似性指数进行群落相似性及聚类分析,结果表明,嵊泗列岛潮间带底栖动物群落结构可聚为两大类型,从结构上看.近外海底栖动物群落为近岸及外海群落的过渡类型.

摘  要:
In this paper, the Shannon-Wiever diversity index H' (S), Pielous species uniform index (J),Margalef specics abundancc index (d) and McNaughton dominant degree (D) are used to conduct the numcrical analpeis of species diversity of bcnthic invertebrate community in rochy intcrtidal zone of Shengsi archipclago. The rcsults show that from neritic zone to off shore, thevalucs of H' (S), J and d have an increasing trend, and D is in reverse. In each sampling section, bigger valucs of H' (S) and J appear in different seasons, the former in Spring and Autumn, and thc later in Spring and Winter. d value is different for each section, bigger D valueappcars in Summer and Auttunn. Whiftaker-Fairbanks community coefficient and Bray-Curtiscommunity similarity index are used to deal with the community similarity and cluster analpeis.The results show that the benthic invertebratc community in rocky intertidal zone of Shengsiarchipelago can be clustered into two type. The community structure of benthic invertebrates innear-shore is an interim type betwecn those in neritic zonc and off-shore.
