微型与微微型真核浮游生物通常是指粒径在0.2~20 μm之间的真核浮游生物。高原盐湖中微型与微微型真核生物具有丰富的遗传多样性，近年来对高原盐湖中微型与微微型真核生物的研究日渐增多。本文综述了国内外微型与微微型真核浮游生物主要类群的分类学和多样性研究进展，论述了青藏高原柴达木盆地盐湖微型与微微型真核浮游生物的群落结构、在不同盐湖中的分布差异及分子生物学研究方法自身的局限。最后对中国未来加强盐湖中微型与微微型真核浮游生物研究提出了4个建议：加强盐湖微型与微微型真核浮游生物遗传多样性研究，开展盐湖微型与微微型真核浮游生物的纯培养技术研究，充分挖掘盐湖微型与微微型真核浮游生物在生物进化研究中的潜力，以及推动盐湖微型与微微型真核浮游生物功能研究。
The Saline Lake storage of the rich mineral resources and biological resources provides an optimum contribution to the economy and the development of industry and agriculture. The eukaryotic pico-and nano-plankton is usually defined as a plankton in the range from 0.2 to 3 μm diameter. The high genetic diversity of the eukaryotic pico-and nano-plankton communities is observed in the HighMountain saline lakes. In recent years, the eukaryotic pico-and nano-plankton attracts attentions of many researchers and many useful observations were made in the literature. The present paper summarizes the recent research progresses in systematic and biodiversity of the eukaryotic pico-and nano-plankton, the composition and the distribution of the inhabiting saline lakes in the Qaidam Basin of the QinghaiTibetan Plateau. And it is pointed out that each kind of molecular biology research techniques has limitations. Some suggestions are made about the studies of the eukaryotic pico-and nano-plankton inhabiting saline lakes, including how to promote the research of genetic diversity of eukaryotic pico-and nano-plankton inhabiting saline lakes, how to carry out the research work based on the microbial cultivation and the pure culture isolation for eukaryotic pico-and nano-plankton inhabiting saline lakes, how to tap the potential of research for the evolutionary studies based on the eukaryotic pico-and nano-plankton inhabiting saline lakes, and how to promote the studies of the biological functions of the eukaryotic pico-and nano-plankton inhabiting saline lakes.
