| 摘 要： | 为了解浙江苍南海域无居民海岛岩相潮间带生物群落组成与结构，于2019年3月对该海域内11个无居民海岛进行了潮间带生物调查，对采集到的样品进行鉴定，并计算了栖息密度、生物量和生物多样性指数。11个无居民海岛共鉴定出58种潮间带生物，平均栖息密度和平均生物量分别为857±205 ind/m2和2 847.83±1 032.50 g/m2，各断面的Shannon-Wiener多样性指数H′、Pielou均匀度指数J和Margalef丰富度指数D范围分别为1.07~1.61, 0.66~0.83和0.54~1.30。与大陆沿岸潮间带相比，无居民海岛生态系统独特，拥有更多的生物资源，具有重要的生态价值，需要重视并加强保护。

| Abstract: | In order to study the composition and structure of rocky intertidal benthos community in uninhabited islands in Cangnan, Zhejiang, the intertidal benthos investigation was carried out on 11 uninhabited islands in March 2019. The collected samples were identified, and the abundance, biomass and biodiversity indexes were calculated. A total of 58 intertidal benthos species are identified in 11 uninhabited islands, the average density is 857±205 ind/m2 and the average biomass is 2 847.83±1 032.50 g/m2, the Shannon-Wiener diversity index H, Pielou evenness index J and Margalef richness index D are 1.07-1.61, 0.66-0.83 and 0.54-1.30, respectively. Compared with the mainland coastal intertidal zone, uninhabited islands have more distinct ecosystems with rich and diverse biological resources and important ecological values. It is suggested that uninhabited islands should be protected. |
