Study on Stream Algae in Shuishentang Spring,Shanxi

Shuishentang Spring,located in Guangling County,Shanxi ,is a larger spring with rich algae resources.The flora and feature of stream algae in Shuishentang Spring has not been previously reported except for the occurrence of some species.In the research,65 species of algae were found,representing 4 divisions,21 families and 37 genera.Bacillariophyta was the most diversified division,including 42 species 10 families and 20 genera,which were accounted for 64.42 %.Chlorophyta was ranked as second,including 13 species,in 7 families and 10 genera,which were accounted for 20.00 %.The third was Cyanophyta,including 9 species from 3 families and 6 genera,which were accounted for 13.85 %.Charophyta had the least species,with only 1 species,which were accounted for 1.53 %,Based on the study of algae communities by using some algological parameters,the water quality of the spring was evaluated.The results showed that the spring belonged to an eutrophic water body.
