Abstract
The present study aims to evaluate the desertification hazard and determine the effective criteria affecting desertification in Abu-Ghoveyr Plain in Ilam Province, using the 9 criteria Iranian Model of Desertification Potential Assessment To this end, first, work units maps (geomorphologic facies) were created using slope, geology, and land use maps. Using this method, work units were considered as the main unit of desertification and a map was generated for each index according to assigned weights, such that the qualitative map of the desired criteria were obtained using the geometric mean of indicators. Then, through integration and determining the geometric mean of layers obtained from criteria and finally classification of the obtained maps, map of the current status of desertification in the studied area was prepared. The obtained results indicated that 31.67% of the area was in the medium class of desertification (II) and 68.33% belonged to the intense class (III).
