摘 要：
This paper deals with the elassification of the 52 fypical probiles of soda sa line soils data got in Xinjiang in 80's ly means of pricipal component analysis. The resulls showed that the soils could be distinguished into four types.
The indexes of interclass delimitation for soda saline soils in Xinjiang are discussed. Five indexes including total sails, pH, total alkalinity, residual sodium carbonate and(CO_3~(2-)+HCO_3~-)/(Cl~-+SO_4~(2-) were used as the indexss in which soda saline soils in whole profile (0～60cm), tolal alkalinity and residual sodium carbonate are considered as the more important indexes.
