摘要：Erosion is a phenomenon during which soil and sediment materials are transferred bysuch damaging factors as water and wind. The type of erosion, of course, is differentin various climates. As an example, in wet and semi-wet areas, water erosion is morelikely than wind erosion. In turn, wind erosion is the main reason for damaging andtransferring soil and sediment materials in arid and semi-arid zones, which can covertalented lands and bring about indispensable damage to land administrators. Winderosion in arid zones is one of the most important processes of desertification, whichis considered in different forms and in various models. Wind erosion status wasinvestigated using the IRIFR method. In this method, nine parameters affecting winderosion process including lithology, morphology and relief, wind velocity, soilcharacteristics, type and plant cover percentage, wind erosion features, soil moisture,type and distribution of sandy dune, land use and land management were considered.Ultimately, wind erosion index was classified in five classes. ArcGIS 9 was used toanalyse and prepare the layers of quality maps to integrate the individual sub-indicatormaps. Results show those areas classified under moderate category have a greaterextent (61%) in the study area while areas under high and very high hazard cover 15%of lands.
