摘　　要：白水江国家级自然保护区是甘肃省生物多样性最为丰富的地区,但是境内的藻类资源状况未见报道过。在实地调查取样的基础上,初步鉴定出白水江国家级自然保护区境内的藻类共4个门60属161种:硅藻门种类最多,有91种,占总种数的56.5%;绿藻门次之,有41种,占25.5%,其次是蓝藻门,有26种,占16.1%;裸藻门最少,共3种,占1.9%。从分布上看,铁楼的种类最多,有81种,然后依次是刘家坪有73种,邱家坝61种,石林谷48种,碧口47种。我们的名录对于了解该保护区的生物多样性提供了基础材料。The checklist of freshwater algae in Baishuijiang National Nature Reserve is preliminarily reported.＂ According to the classification system of the Chinese freshwater algae, 160 alga species subject to 4 phyla and 60 genera have been identified. Among them, Bacillariophyta includes the most with 89 species, accounting for 55. 6% of total species. Chlorophyta is ranked as the second one with 41 species, accounting for 25.6 % of total species. The number of species of Cyanophyta is ranked 3rd with 27 species , accounting for 16.9 % of total species. Genus Euglenophyta is the least one, only containing 3 species. The checklist we reported will be an important document to reveal biodiversity status in Baishuijiang Nature Reserve.
