| 摘 要： | 定量分析从大连石槽岩礁潮间带共采得１４种海藻和２５个附植小型动物样品。指出海洋线虫和底栖桡足类是永久性小型动物中占优势的类群，平均相对丰度分别占４１％和２８．３％。共鉴定出４６种海洋线虫。沉积食性的锐棘线虫（Ｔｈｅｒｉｓｔｕｓａｃｅｒ）的优势和普遍分布，指出本研究海域的隐蔽性，海藻上沉积了较多的有机碎屑和沉积物。将附植小型动物的数量与其他海域进行比较，并讨论了附植小型与附植大型动物的关系。

| Abstract: | A total of 25 meiofauna samples were collected from fourteen macro-algal species from the rocky beach at Shicao, Dalian in April 1990. The permanent meiofauna were dominated by free-living marine nematodes and harpacticoid copepods,whose mean relative abundances being 41% and 28% respectively, and their abundances and relative dominances appeared to be related to their feeding habits and the degree of shelter. Forty-six nematodes species and taxa were identified, of which Monhysterids and Chromodorids were the most dominant group. The Monhysterid Theristus acer contributed 40% to the overall abundance, and its dominance and distribution on the most macro-algal species showed the relative shelter and accumulation of detritus in the study area. A comparison was made between the present phytal meiofauna abundance and that of other areas. |
