In recent years, the occurrence of water and wind erosion indifferent parts of country due to the changes of land use from the forest andpasture into the agricultural and also construction of communication lineshave increased. The study and research on this phenomenon, the effectivefactors in creating them and also identification of geomorphology faciestypes are necessary to prevent the waste of water and soil resources and theirdamages. In this study, in order to homogenize the studies and prevent thedisperse works; we have tried to generate a base map based ongeomorphological one. Thematic maps such as lithology and slope erosionfacies map were also combined and finally obtained a homogeneous unitmap (work units) which has a special place in natural resources studies.Considering the characteristics of each of these homogeneous units, thereshould be a special planning to protect and restore them. Therefore,considering the nature of this study, it can be a basic platform and be used inother studies. According to researches, 12 geomorphological facies wereidentified in the region. These facies are in mountain and pediment units; sothree types of pediments including erosion, appendage and covered oneswere distinguished in pediment unit. Different facies with specificcharacteristics were determined in each of these types. Finally, consideringthe natural power (potential) of facies and current status of land use, amanagement program was suggested.
