Wind erosion is the main reason for damaging and transferring soil and sediment materials in arid and semi arid zones, which can cover talented lands and bring about indispensable damage to land administrators. Wind erosion in arid zones is one of the most important processes of desertification. A vast part of Aghqalla-Gomishan is arid and semi arid climate. Because of special climate, edaphic, and geomorphologic condition, the area is highly suitable for wind erosion and desertification. So, evaluation wind erosion is required for proper land management planning. To develop an wind erosion control program in Aghqalla- Gomishan plain, a Scalogram Model has been initiated to identify the areas that truly require immediate improvement practices. The model also has been used to make possible priority in rating of areas and corrective measures. For this purpose, the geomorphological units and the characteristics that influence the erodibility of landscapes and also the related measures have been arranged to identify the volume and intensity of practices. The study provides numerous conclusions which may be useful for combat desertification managers and conservationists in resource conservation projects.
