%X In the west of Songnen Plain , the saline alkali degree is high in saline water body and marsh where pH value is generally over 8 0, and the chemical type of water is HCO 3 2- -Na +. Through analysis on the basic saline alkali variables such as O 3 2- , HCO 3 2- , Cl -, Ca 2+ , Mg 2+ , SO 4 2- , Na + etc. and the composed variables such as (Cl -+SO 4 2- )/HCO 3 2- and Na +/(Ca 2+ +Mg 2+ ), the relationships between different variables were found, and the discriminating function and critical region map were got basing on the pH value, by which the significant study method on saline alkali water body was attempted.
