摘　　要：为了探索石灰华扇沉积物中微型生物多样性特征，作者2006年7～9月对贵州中部马脚冲瀑布石灰华扇进行了野外生态学调查，采集样品和标本50份。经室内初步分析和鉴定，该瀑布石灰华扇中含有4大微型生物多样性类群共25个物种，它们是蓝细菌（Cyanobacteria）1个种，原生动物（Protozoan）16个种，绿藻（Green algae）1个种，硅藻（Diatoms）7个种。此外，石灰华扇中还发现了苔藓植物（Bryophytes）6个种。石灰华扇沉积物的形成，是微型生物多样性一石灰华扇沉积相互作用的地质生态学结果。For the research of characteristics of biodiversity of microorganisms from a tufa fan deposition of karst waterfall, the authors conducted out a field work at Horse＇s- hoof Waterfall in Guizhou from July to September in 2006, After identification and analysis in laboratory, 25 microorganisms taxa belonging to four groups have been found from this tufa fan deposit at Horse＇s -hoof Waterfall. Among them, there are one species for cyanobacteria while sixteen for protozoan , one for green algae and seven for diatoms. And six taxa for bryophytes also were found from same tufa fan. The relationship between biodiversity of microorganisms and tufa deposition at activa waterfall have been disscused in this paper.
