THE SPECIES COMPOSITION AND DISTRIBUTION OF EUGLENOPHYTA IN SALT LAKES AREA IN YUNCHENG

Xie Shulian, Ling Yuanjie and Li Zhen)(Department of Life SCience, Shanxi University, Taiyuan 030006)(Shanxi Education College, Taiyuan 030031)  
A total of 83 species euglenoids were collected from the salt lakes area in Yuncheng, Shanxi, North China They belong to 10 genera and 77 taxa to green euglenoids and only 6 taxa to colourless euglenoids.Conceding the salt concentration of the water, 4 types can be divided, i. e. fresh water (salt concentation 0.001-0.05%), mesohalinous water (salt concentration 0.05-3%), euhalinous water (salt concentration 3-4%) and polyhalinous water (salt concentration 4-34.7%). Because of the effect of different content of salt the difference is evident in the distribution of euglenoids in 4 types of the water. That is the more the content of salt is, the fewer the number of euglenoids is. In addition, there are obvious changes in number of the euglenoid species in salt lakes area in different months.
