摘　　要：随着对水生态系统结构与功能的深入研究,自由生活的异养鞭毛虫在水生态系统中的作用成为当前生态学领域的热点之一。已有的研究结果表明,异养鞭毛虫物种丰富,摄食方式多样,周转迅速,是微食物环的重要成分,在水生态系统中起着十分重要的作用。异养鞭毛虫物种多样性及生态学方面的系统研究将有助于对水生态系统结构、功能和过程深入了解。综述了异养鞭毛虫多样性、群落结构、摄食生态学以及在氮、磷循环中的作用,分析了其在生态系统中的功能。As increasing attention has recently been ecological function of free-living heterotrophie flagella paid to the structure and function of the water ecosystems, the tes in water ecosystems has emerged as a central issue in water ecological research. Researches have shown that heterotrophic flagellates are being important members of microbial food webs. Strengthen and expand the researches on heterotrophic flagellate diversity, community structure and their function in nutrient recycling will contribute to understanding on the structure, function and the process of water ecosystems. In this paper, species diversity, community structure and feeding ecology of heterotrophic flagellate were summarized. The mechanism in nutrient recycling and the function in water ecosystem of heterotrophic flagellate were also discussed.
