中文摘要：
在山西运城盐池湖区采到的藻类植物共5门（不包括硅藻门），30科，70属，222种（含变种和变型）．其中蓝藻门4科17属35种，绿藻门19科40属93种，裸藻门5科10属83种，黄藻门1科1属2种，轮藻门1科2属9种．该湖区的水体根据含盐量的不同可分为4种类型：淡水水体（含盐量〈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％）．由于受含盐量的影响，藻类植物在4种水体中的分布有明显差异，随含盐量增加，种类数减少．
英文摘要：
A total of 222 species of algae were collected from the salt lake area in Yuncheng, Shah 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.
