Soil quality assessment is of great significance for assessing soil status and productivity，promoting sustainable agricultural development，and protecting the ecological environment.In this study，the physical and chemical properties of salinized soil in seven irrigation areas within the oasis of the Manasi river basin were analyzed，and the quality of salinized soil in oasis agricultural areas of the Manasi river basin was evaluated by principal component analysis.The results showed that:(1) The minimum data set affecting the soil quality of oasis agricultural areas in Manasi river basin included total soil salt，organic matter，pH value，Na+，Mg2+，alkali-hydrolyzable nitrogen，and soil texture；(2) The degree of soil nutrient deficiency in oasis agricultural areas was ranked as available potassium>available phosphorus>available nitrogen>organic matter；(3) The soil quality of oasis agricultural area was mainly graded II [0.65
