摘要
１９９２年５月～１９９３年３月对南麂列岛潮间带１７条断面和本岛陆域环境进行了全面的生态调查和环境质量评价。共获大型底栖动物２７８种，大型藻类１２１种，微小型藻类１５５种。研究结果表明，本区种类组成以软体动物最为丰富，生物数量以甲壳动物占绝对优势。区系特点与福建、广东沿岸较为相似。生物量以春季为高，栖息密度在秋季有一明显高峰。生物量的大小顺序为开敞岩礁大于隐蔽岩礁大于巨砾大于泥滩大于沙滩。种类组成、数量分布和群落结构与底质类型、波浪作用关系密切。文中还对生物的地域断裂分布现象作了探讨，对环境质量保护问题提出了建议。
cological study and environment qualitative survey were carried out in the intertidal zone and land area of Nanji ArchipelagO during May 1992-March 1993.278 species of macrobenfauna, 121 species of macroscopic algae, 276 species of nannomeioflora were obtained in total. Molluses is the most abundant group in benthic species composition, crustaceans in absolutly dominant position in biomass. The feature of fauna in Nanji is more similar with that in Fujian and Guangdong. The highest season of biomass is in spring, but an outstanding peak in density occured in Autumn. The order of dinsity and biomass from high to low is as following: exposed reef > sheltered reef > gravel bank > mudy flat > sandy beach. The type of bottom and wave actions are very closely related tO species composition, distribution of individual abundant and community structure in the intertidal zone. The characteristic of the breakage distribution in biopegraphic region is discussed. borne ideas for protecting the environment of Nanji Island are suggested.
