2010年4月—2011年3月对烟台养马岛潮间带大型海藻进行了逐月调查.在养马岛潮间带共设置了A、B两个点,对大型海藻物种组成、生物量以及与环境变化的关系进行了研究.结果表明:调查区域共有大型海藻35种,其中红藻24种,占总数的68.6%;绿藻6种,占总数的17.1%;褐藻5种,占总数的14.3%.夏季优势种以褐藻和绿藻为主,秋、冬、春季优势种以红藻和褐藻为主,鼠尾藻在各季节中均为优势种.大型海藻生物量呈现夏季高、冬季低的特点,生物量最高值出现在6月,A、B采样点大型海藻生物量最小值分别出现在1月和11月,具有温带海域藻类变化特点.温度、营养盐和p H对大型海藻生物量有显著影响. From April 2010 to March 2011, a monthly survey was conducted on large-scale algae in the Yangma island intertidal zone of Yantai. A and B were set up in the intertidal zone of Yangma Island, respectively. Species composition, biomass 35 species of large-scale algae, of which 24 species of red algae, accounting for 68.6% of the total; 6 species of green algae, accounting for 17.1% of the total; 5 species of brown algae, accounting for the total 14.3% .The main dominant species in summer were brown algae and green algae, while the dominant species were red algae and brown algae in autumn, winter and spring.The species of algae were the dominant species in all seasons.The biomass of large algae showed the highest in summer, In winter, the maximum value of biomass appeared in June, and the minimum biomass of large algae in sampling points A and B appeared in January and November, respectively, with the characteristics of algae change in temperate zone.Temperature, Seaweed biomass has a significant impact.
