Abstract
Arid and semi-arid region of the world are located in 20 to 40 northern and southern latitude. Iran is located in this region too, that is known as universal erosion belt. Cognizance of taking region counted as the most fundamental and basic things. Critical center of Nikshahr with 23684/8 hr. width is set in north of Nikshahr situated in southwest of Sistan and Baluchistan and the southeast of Iran. This sector arena encompass southeast to northwest direction, that from geomorphology view has 2 units of plain and mountain. In northwest exit blowy erosion form in the form of Barkhan, lateral Barkhan in width seif and silk. For signification origin this hills we utilize discovering. Original method sandy hills of Iran and based on during two phases of orientation and location counter, that orientation is entail of gathering of local data of blowy erosion estate, survery and comparison aerial and satellite pictures with different time duration, survery public morphology and sandy hill unit and survery regional wind and location counter is entail of local geomorphological study and samplery of faces and doing granalometery, morphoscopy and inorganic test origin of sandy hills was determined. Based on conclusion of the study which was done on erosive wind in the region they have north to northwest orient. Also faces sensitivity to blowy erosion with using Eafer method is assessed from very low to high.
