摘　　要：在山西运城盐池湖区采到的裸藻门植物共10属83种（包括变种和变型），其中，绿色棵藻类77种，无色裸藻类6种。该区域的水体根据其含盐量的不同可分为4种类型：淡水水体（含盐量0．001—0．05％）、混盐水体（含盐量0．05—3％）、真盐水体（含盐量3—4％）和高盐水体（含盐量4—34．7％）。由于含盐量不同的影响，裸藻门植物在4种水体中的分布有明显差异，总的趋势是裸藻门植物的种数随着含盐量的增加而减少。此外，裸藻门植物在盐池湖区的分布也有明显的季节变化。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.
