| 摘 要： | 本文基于对七星列岛大型底栖藻类的实地调查,结合浙南3个列岛(七星列岛、南麂列岛和洞头列岛)和浙北3个列岛(渔山列岛、中街山列岛和马鞍列岛)大型底栖藻类物种组成的有关文献,构建大型底栖藻类基础数据库。采用平均分类差异指数△~+、分类差异变异指数∧~+、G-F多样性测度指数和相似性系数开展分类多样性研究。结果显示:6个列岛藻类在目级和科级的相似性很高,其值均在0.800以上;洞头列岛的△~+值最高(77.42),中街山列岛最低(72.65),这表明洞头列岛大型底栖藻类类群间的亲缘关系较远,中街山列岛藻类类群间的亲缘关系较近;七星列岛的∧~+值最高,达942.00,南麂列岛最低,仅865.12,这表明南麂列岛大型底栖藻类在不同分类阶元分布最均匀,七星列岛的藻类分布较集中;南麂列岛无论是F指数、G指数还是G-F指数的值均比其他5个列岛高,依次为18.62,4.40和0.76,这说明南麂列岛藻类的生态位分化程度较高。本研究构建了6个列岛大型底栖藻类资源与分类多样性基础数据库,为有效保护和管理大型底栖藻类提供了理论依据。

| Abstract: | This paper summarizes the field investigation of benthic macroalgae in Qixing Islands, Zhejiang Province, and combines available literatures data of the benthic macroalgae from other five archipelagic islands of the province, including Nanji, Dongtou, Yushan, Zhongjieshan, and Ma''an Islands, and established the database of the benthic macroalgae. The results indicate that the taxa of the six islands were similar in the order and family level. The maximum average taxonomic distinctness index (77.42) was found in Dongtou Islands, and the minimum in Zhongjieshan Islands (72.65). Thus, the genetic relationship of the benthic macroalgae in the Dongtou Islands is more distant than those of the other five islands. The maximum variation in taxonomic distinctness index was revealed in the Qixing Islands (942.00), and the minimum in Nanji Islands (865.12). Therefore, the taxonomic distribution of benthic macroalgae in Nanji Islands was the evenest among all the islands. Moreover, Nanji Islands ranked No. 1 in F index (18.62), G (4.40) and G-F index (0.76) among all islands, indicating that the algae species of Nanji Islands featured higher niche differentiation degree. This paper shall provide the basic natural information for effective protection to benthic macroalgae resources these islands. |
