摘要: 微生物是一群以分解代谢为主的重要生物类群,其生物学多样性十分丰富。但由于它们的微观性,尤其原核微生物简单的单细胞结构、以无性方式进行快速地繁殖而造成的无准确的基线难以对其进行种群数目和数量的统计,因而对微生物的多样性研究远没有宏观生物那样深入和受到重视。本文根据原核微生物的特性,从其物种、所代表的进化分支、生理代谢类群及遗传背景几个方面简述了它们的多样性及重要意义,意在引起科学界和全社会对这类生物资源的认识和保护的重视。

Abstract: Microorganisms are an important group of organism mainly performing catabolic metabolism, which display extreme abundance in biodiversity. However, due to their microscopic sizes, especially prokaryotes with simple unicellular structure, their asexual propagation, their rapid replication and the lack of base line inventory of their groups and quantity, the biodiversity of microorganisms has so far not been studied thoroughly and has been paid little attention compared with macro organisms. In the present paper, the biodiversity of microorganisms is reviewed briefly, with consideration of the following aspects: species diversity, diversity of phylogenetic lines, physiological diversity and genetic diversity. The aim is to improve awareness of investigation of microorganism resources, not only in the scientific community but also in society as a whole.
