摘　　要：在青岛太平角海区潮间带设立样地,运用最近邻体法进行了鼠尾藻种群分布格局的研究;利用野外观测数据编制了静态生命表,运用静态生命表、存活率曲线以及生殖力表,研究了鼠尾藻种群数量动态变化过程,分析了影响种群数量变动的因素。结果表明,鼠尾藻种群的生态分布格局为聚集分布,面对复杂多变的生态环境,鼠尾藻种群表现出r-对策者和k-对策者两种生态对策,从而确保鼠尾藻种群数量在自然环境中能够保持稳定增长,并很容易在潮间带群落中形成优势种群。The analyses of distribution patterns of the populations of Sargassum thunbergii in the intertidal belt of Qingdao Taipingjiao area were conducted with the nearest neighbor technique.Based on the data obtained in the field,the help of the static life table,survival curve and fecundity table,the process of dynamic change of the population of S.thunbergii,and factors affecting the numeric dynamics were studied.The results showed that the populations of S.thunbergii were aggregative.To adapt the varied environment,the populations of S.thunbergii evolved two ecological strategies：r-strategy and k-strategy,which facilitated the steady increase of the population,accordingly,the population usually got predominant among the intertidal community.
