One of the main objectives in urban environment is to guarantee a high level life quality for citizens by improving environment's quality where the level of pollution does not cause harmful effects on human health and other parts of biological system. Western part of Tehran was chosen as the case study and three land uses (agricultural, park, vacant lot) were recognized there. 20, 16 and 20 samples were collected from these land uses respectively. Based on assessment's purposes lime, pH, EC, total nitrogen, phosphorus, potassium, sodium, organic carbon, soil texture, bulk density, saturated soil percent and available water were measured in laboratory. Statistical analyses using One-way ANOVA indicated that organic carbon, total Nitrogen, sodium, phosphorus, Lime and potassium have significant changes in different land uses. Factor Analysis identified five factors that explained for 72.62 % of the variance. Finally, the soil quality model was determined based on the variables which have the most communality using redundancy analysis and discriminant function analysis. The results showed that organic carbon, lime, pH, P, BD and TN have the highest canonical coefficient and therefore, these variables are the effective parameters on urban soil quality indicators.
