Taking the lakeside oasis in the western lakeside of Bosten Lake as the researcharea，the characteristics of soilsalinity in the study area were analyzed using the Pearson correlation analysis and principal component analysis.Resultsof the study showedthat:(1)The salt type of the surface soil was mainly chloride -sulfate，which accounted for more than 60.00%.The coefficients of variation for the soilsalinity，Na ++K+，Ca2+，SO42-，and C1 -were all higher than100.00% and were strong，and the coefficient of variation for HCO 3-was higher than 90.00% and less than100%，and wasmoderate；Mg 2+ showed strong variability and medium variability in 0～ 10 cm soil layer and 10～ 30cm soillayer，respectively，with the coefficient of variation of 132.85% and93.30%，respectively；(2)Therewas a very significant positive correlation between the soil salinity and main ions in the soil( P<0.01).The soil salinity showed the strongest correlation for Na++K+with the correlation coefficient of0.99，whereas the soil salinity showed the lowest correlation for Mg2+with the correlation coefficient of0.37.(3)Among of the different landusetypes，the soil salinity was rankedas:the unusedland(11.82 g·kg -1)> forestland(5.98 g·kg -1)>grassland(4.89 g·kg -1)>cultivated land(2.50 g·kg -1)，the coefficient of variation of the soil salinity was rankedas:cultivated land>grass land>forest land>unusedland，the maximum value of the coefficient of variation was176.31%，whereas the minimum value of was87.97%.(4)The characteristic factors of soil salinity were Na ++K+，HCO3-，and SO 42-，the integrated score model of principal component wasY=0.09(HCO 3-)+0.30(Cl-)+0.10(SO42-)+0.17(Ca2+)+0.18(Mg2+)+0.09(Na++K+)，the average score of the composite score was0.58，and the coefficient of variation was122.00%， which belonged to the strong variability.
