0.05) on different soil properties. Also, the minimum effective properties on soil quality were determined by the minimum data set (MDS) with the help of principal components analysis (PCA). Finally, soil quality index values were calculated using discriminant analysis (DA). The results of PCA and DS showed that the EC, OM, CaCO3 and pH were influenced by soil texture, slope and elevation, respectively. Then, the comparison of mean soil quality values using the least significant differences (LSD) indicated poor soil quality on slopes less than 15% and elevations above 2000 m. The results of this research could be used for choosing appropriate management practices to control land degradation and to achieve sustainable development goals in different ecosystems of Shazand Watershed.]]>
