The characteristics of the soils of the region were collected from the soil studies report of Harzandat Marand Plain. In order to prepare spatial distribution maps and study spatial patterns, the data of the points collected from the soil were generalized to the regional level during the interpolation process. To determine the relative weight or importance coefficient, the selected criteria were compared using AHP model and hourly quantitative table. After adding the final weight of the criteria in ArcGIS software, the final maps were prepared based on the normalized final weight with the overlay model.</span></span></span></span><br>
