摘要
对北麂列岛潮间带蔓足类群落结构的研究表明 ,该列岛蔓足类群落属外海高盐类型 ,群落结构简单 .用 Shannon- Wiever多样性指数 H′( s)、Pielou均匀度 J、Margalef种类丰度 d及 Mc Naughton优势度 D 4 个测定群落种类多样性指标进行数值分析 ,结果表明 ,从北到南 ,H′( s)、J、d值呈现逐渐增加的趋势 ,而 D值则有逐渐减少的趋势 .各断面的多样性指数 H′( s)及种类均匀度 J值以春、夏季较高 ,d值夏、秋季较高 。
The intertidal cirripod community structure in Beiji archipelago was investigated, the cirripod community structure is belong to hight salty ones, and is very simple. The Shannon-Wiever diversity \$H′(S)\$, Pielous species index\$(J)\$, Margalef species abundance index\$(d)\$ and McNaughton dominant degree \$(D)\$ are used to conduct the numerical analysis of species diversity of benthic cirripod community in rocky intertidal zone of Beiji archipelago. The results show that, from North to South, the values of \$H′(S)\$, \$J\$ and \$d\$ have an increasing trend, and \$D\$ is in reverse. In each sampling section, bigger values of \$H′(S)\$ and \$J\$ appear in Spring and Summer, that of \$d\$ appears in Summer and Autumn, and \$D\$ value is different for each section.
