中文摘要：

2013年6月-2014年6月对青岛岩礁潮间带鼠尾藻、孔石莼、蜈蚣藻附植小型底栖生物进行了连续13个月的逐月采样，对小型底栖生物的丰度、生物量、生产量、类群组成及其季节动态进行了研究。共鉴定出小型底栖生物16个类群。鼠尾藻附植小型底栖生物的年平均丰度和生物量分别为7×103 ind·g-1 dwt algae·a-1和56×103μg·g-1 dwt algae·a-1。孔石莼附植小型底栖生物的年平均丰度和生物量分别为2×103 ind·g-1 dwt algae·a-1和8×103μg·g-1 dwt algae·a-1。蜈蚣藻附植小型底栖生物的年平均丰度和生物量分别为3×103 ind·g-1 dwt algae·a-1和16×103μg·g-1 dwt algae·a-1。三种藻类附植小型底栖生物平均丰度和生物量的高低依次为：鼠尾藻＆gt;蜈蚣藻＆gt;孔石莼。附植小型底栖生物及其主要类群的丰度具有明显的季节变化，其中鼠尾藻、孔石莼附植小型底栖生物丰度与海水温度和盐度显著相关。附植小型底栖生物的丰度还可能与藻类生长周期关系密切，三种藻类附植小型底栖生物的丰度的最高值均出现在藻类的快速生长期之前。三种藻类附植小型底栖生物群落差异显著，鼠尾藻上线虫为最优势类群，孔石莼和蜈蚣藻上底栖桡足类为最优势类群。藻类形态和藻类生活周期是影响附植小型底栖生物类群组成、丰度和生物量的关键因素。

英文摘要：

The phytal meiofauna on the seaweeds Sargassum thunbergii, Ulva pertusa Kjellm and Grateloupia filic ina were surveyed monthly over an annual cycle from June 2013 to June 2014 at the rocky intertidal zone in Qingdao. Meiofaunal abundance, biomass, production, faunal composition and their seasonal dynamics were studied, and 16 faunal groups were identified from the three seaweeds. On S. thunb e rgii, the annual average abundance and biomass were 7 × 103 ind·g-1 dwt algae·a-1 and 56 × 103μg·g-1 dwt algae·a-1, respectively. On U. pertusa Kjellm, the annual average abundance and biomass were 2 × 103 ind·g-1 dwt algae·a-1 and 8 × 103 μg· g-1 dwt algae·a-1, respectively. On G . filic ina, the annual average abundance and biomass were 3 × 103 ind·g-1 dwt algae·a-1 and 16 × 103 μg·g-1 dwt algae·a-1, respectively. The three seaweeds with the greatest number of abundance and biomass were, in order, S. thunbergii＆gt;G. filicina＆gt;U. pertusa Kjellm. The abundance of meiofauna and its main groups exhibited significant seasonal variation. The meiofaunal abundance on S. thunb e rgii and U. pertusa Kjellm significantly related with seawater temperature and salinity. Phytal meiofaunal abundance might also be closely related with algal growing cycle, the highest meiofaunal abundances on the three seaweeds all appeared just before the algal rapid growth stage. Meiofauna communities showed significant difference among the three seaweeds. Ne matoda was the most dominant group on S. thunb e rgii, while Cop e p oda was the most dominant group on U. pertusa Kjellm and G. filicina. The morphological structure and life cycle of seaweed were possibly the key factors influencing phytal meiofaunal abundance, biomass and faunal composition.
