Chanan Irrigation Area in Ili of Xinjiang was selected as the study region, the soils were graded according to the salinization level, the characteristics of soil salts were analyzed by using correlation analysis and principal component analysis, and the regional influential factors on soil salinity were also qualitatively determined. The results show and that soils in the Chanan Irrigation Area are mainly alkaline, the influence of HCO₃^- on soil pH is most. Salinization soil constitutes of about 25% of the total Irrigation Area, indicating the study area is facing great risk of salinization. Correlation analysis showsed HCO₃^- , Cl^-, SO₄^2-, Ca²⁺, Mg²⁺, Na⁺ and K⁺ are the main ions of soil salt, all ions have positive correlation with total salt content, among of which, SO₄^2- and Mg²⁺ are the most correlated anion and cation respectively. The result of PCA disclosed that HCO₃^- , Cl^-and K⁺ are the dominant influential factors on soil salinity characteristics in Chanan Irrigation Area. The qualitative analysis of the regional influential factors suggest HCO₃^- and pH of soil in Chanan Irrigation Area are comprehensively influenced by river and groundwater, while other salt ions are mainly affected by rivers.
