Abstract

Abstract
The intensity of wind erosion desertification processes means reducing the ecological and biological land that occurs naturally or artificially by human activity. So far a large variety of methods to estimate the wind erosion rate is presented by various experts around the world. Because not consistent with climate models provided by experts in other countries, Iran, in 1375 IRIFR.E.A experimental model was devised and proposed. Ghahavand plains in areas which are the province of the destruction of production in the decades to face the desert. The study area is located in Sanandaj parallel to the Zagros region and has been strongly altered and magmatic activity in it. The purpose of this study, mapping of wind erosion area is IRIFR.E.A model. For this purpose, the 9 factors affecting wind erosion on the basis of the model in seven units geomorphology and geology, soil, vegetation and weather data were analysised. According to the results found that most points related to changes in land use and zoning salt is granulated or saline flats, and the last one on the regional of the village. Also according to the assessments of the area showed that 7.04percent in grade low and, 23.59 percent in grade average and 69.35 percent in the class wind erosion is very intensity.
