In this study, Wuhai in Inner Mongolia and Lingwu in Ningxia in the eastern part of the northwest arid desert region were used as the study area, and six types of soil profiles were selected on artificial green areas to study their salinization characteristics, namely, homogeneous sandy soil (A), homogeneous loamy soil (B), upper sand lower loam (C), upper loam lower sand (D), sandwich type (E) (loam-sand-loam (E1), loam-powder-loam (E2), sand-loam-sand-loam (E3)), and upper loam lower stone (F). In addition, the effects of irrigation, soil physical, and soil depth factors on soil salinization were investigated using redundancy analysis (RDA). The results showed that: (1) the total salt (TS) of soil profiles ranged from 115.5 to 4945.5 mg kg-1. Moreover, 6.7%, 26.7%, 6.7%, 20.0%, 33.3%, and 40.0% of the soils in profile types A, B, C, D, E, and F, respectively, reached light salinization; 13.3%, 20.0%, and 20.0% of the soils in profile types D, E, and F, respectively, reached moderate salinization; in addition, only profile type F showed heavy salinization with a high percentage of 40.0%. On the other hand, soil profile types A, B, D, and F were predominantly surface accumulation type, while soil profile type C was bottom accumulation type. In addition, profiles E1 and E2 in the E-type soil profile were bottom accumulation type, while profile E3 was surface accumulation type; (2) Soil pH and soil SAR ranged from 7.49 to 9.31 and 0.67 to 15.28, respectively; (3) The results of the RDA analysis showed that the first two axes explained more than 74.0% of the soil salinity variance, indicating the obvious relationship between soil salinity and the influencing factors. Silt content, irrigation frequency, clay content, annual irrigation volume, irrigation frequency, and soil depth were the major factors influencing soil salinity in soil profile types A, B, C, D, E, and F, respectively, while soil water content and soil salinity had highly significant co-spatial characteristics (P < 0.01).
