Study on species and distribution of algae in salt lakes area in Yuncheng, Shanxi Province

Abstract

A total of 222 species of algae were collected from the salt lake area in Yuncheng, Shan xi Province , North China, representing 5 didivisions, 30families and 70 genera. Among them 35 speces from 4 families and 17genera in Cyanophyta, 93 speces from 19 families and 40 genera in Chlorophyta, 83 speces from 5 families and 10 genera in Euglenophyta, 2 speces from 1 family and 1 genera in Xanthophyta, 9 speces from 1 family and 2 genera in Charophyta. Concerning the salt concentration of the water, 4 types can be divide, i. e. fresh water (salt concentration 0.05% ) , mesohalinous water (salt concentration 0.05% -3% ), euhalinous water (salt concentration 3% -4% ) and polyhalinous water (salt concentration 4%). Because of the effect of different salt concentration the difference is evident in the distribution of alage in 4 types of the water . It is shown that the higher salinity , the fewer number of species.
