摘　　要：利用 1 997年 7月～ 1 998年 4月在北麂列岛壳菜岙北侧岩礁、海利南岙岙口岩礁、关帝山岩礁及大筲箕屿岩礁 4个断面所采集的样品 ,对北麂列岛岩相潮间带无脊椎动物的群落类型及结构进行了研究。采用 Shannon- Wiener多样性指数 (H′)、Pielous均匀度 (J)、Margalef丰度 (d)、 Mc Naunghton优势度 (D) 4个测定群落种类多样性的指标及 Whittaker群落相似性指数公式进行数值分析 ,结果表明 :该群落属于典型的外海高盐性生物群落。水平变化 ,H′、J及 d值以大筲箕屿岩礁处为最大 ,D值以关帝山岩礁处为最大 ;垂直变化 ,H′、J及 d值为低潮区 >中潮区 >高潮区 ,D值为高潮区 >中潮区 >低潮区 ;季节变化 ,H′和 J值以春季最高、秋季最低 ,d值以夏季最高、冬季最低 ,D值以秋季最高、春季最低。 4个断面群落种类的相似程度较为接近 ,根据相似性指数 I的值 ,可将其划分为开敞性群落组和极开敞性群落组 ,其中壳菜岙北侧岩礁、海利南岙岙口岩礁和大筲箕屿岩礁为开敞性群落组 。The community types and structures of invertebrates of Beiji Islands were investigated from July 1997 to April 1998. The Shannon-Wiener diversity index (H′), Pielous species uniform index (J), Margalef species abundance index (d) and McNanghton dominant degree(D) are used to conduct the numerical analysis of species diversity of invertebrate community in rocky intertidal zone of Beiji Islands. The results show that the biggest values of horizontal changes of H′, J and d appeared near Xiaoqiyu , and subsequent in Haili, Kecaiao and Guandishan . The biggest value of D appeared near Guandishan, and subsequent near Haili , Kecaiao and Xiaoqiyu . The values of vertical changes of H′, J and d are the low-tide area > the mid-tide area > the high-tide area, and D is in reverse . The values of H′and J are the highest in spring and the lowest in autumn, d is the highest in summer and the lowest in winter, and D is the highest in autumn and the lowest in spring. The community types of benthic invertebrates of Beiji Islands are belong to the typical off-shore and high-salty one.
