摘　　要：作为微型浮游动物的重要组成部分,海洋浮游纤毛虫是连接微食物环和经典食物链的重要中介,在海洋浮游生态系统物质循环和能量流动中发挥重要的作用。从20世纪60年代至今,关于纤毛虫丰度和生物量的分布已经积累了大量的资料,目前纤毛虫丰度和生物量分布的研究大部分集中在温带海区,热带和极地海区的研究尚少。本文概述了世界海区纤毛虫丰度和生物量的水平分布、垂直分布特点及周年变化规律。纤毛虫丰度和生物量一般在饵料丰富、生产力较高的海区较高;纤毛虫倾向分布在水体的中上层;纤毛虫的丰度和生物量一年之内呈现双峰型或单峰型,纤毛虫群落的粒级组成一般春季较大,夏季较小,砂壳纤毛虫丰度占纤毛虫丰度的比例一般在夏季或秋季较高。As an important component of microzooplankton, marine planktonic ciliates are the key link between the microbial food web and classical food chain, playing an important role in the material cycling and energy flow in marine planktonic ecosystems. Since the 1960s, studies on the marine ciliate abundance and biomass in the sea areas of the world, especially in the temper- ate regions, have been performed extensively. In this paper, the horizontal distribution, vertical distribution, and annual variation patterns of the abundance and biomass of marine planktonic ciliates in the world sea areas were summarized. Generally, ciliates tend to distribute in the mid- dle and upper water layers, their abundance and biomass are higher in the sea areas with more diet supply and higher primary production and showed a bimodal or unimodal pattern in a year, larger ciliates are more prevalent in spring than in summer, and the contribution of tintinnid to the total ciliate abundance was higher in summer or autumn.
