Abstract: The problem of soil salinization in the oasis of the arid area in spring is very serious. In order to study the characteristics and spatial distribution of soil salinization in a typical oasis area. The pH and salts at different soil depths in the irrigation areas were analyzed by using classical statistics, geostatistical and GIS methods in the 2^nd Division, 31^st Regiment, Xinjiang. The results showed that the pH values of soils in the irrigation area ranged from 8.01 to 8.32 and was alkaline in general. The salt in spring was accumulated in soil surface. The main cations of soil salt composition were K⁺ and Na⁺. The main anion was SO₄²⁻ in the cultivated soil and was Cl⁻ in the uncultivated soil. The arable and non-arable lands were mainly belonged to chloride-sulfate type and sulfate-chloride type, respectively. The contents of soil salts at different depths were strongly different and most of them showed good spatial correlations. The soil salt content at the 40-60 cm soil layer showed a strong spatial correlation. The contents of soil salt in the 0-20 cm, 20-40 cm, and 80-100 cm depths showed a moderate spatial correlation. The contents of soil salts were higher at the 0-20 cm and 40-60 cm depths, ranging from 1.59-8.91 g kg⁻¹, and were lower at the 20-40 cm and 80-100 cm depths, ranging from 2.44-3.95 g kg⁻¹. The spatial distributions of salt contents within the same soil depths were basically same. The areas with high soil salinity were mainly distributed in the middle and northeast of the study area and in the area with high desertification and low terrain, with 3-8.91 g kg⁻¹ salt contents. The soil salt contents were gradually decreased from the middle to the two sides, and was relatively low (1.59-3 g kg⁻¹) in the northwest and southeast of the study area.
