Abstract
Blowy erosion is one of the serious problems of arid and semi-arid regions in the world that threat a large part of human life specially in semi-arid regions of the world in 20 to 45 nor then and southern latitwle. Large part of our country’s lands have exited from ecologic balance state because of different natural and human factors, and arid destroying or region destruction have started there. Blowy erosion, supplant of product dregs, occurrence of sandstorms and dust are among the first obvious effects of this destruction. The region under study with pp602 hr. width is located in the east of Sistan and Baluchistan province in zone of khash city. This confine has two units, four brigades and eight faces. Recognition of taking points or origin of sandy hills is the most important way for battling blowy erosion. Therefore we utilize finding origins method of sandy hills in Iran (Ekhtesasi, et al 1375) and according to it during two phases of orientation and location. Origin of sandy hills was determined, orientation is entail of gathering of local data of blow erosion state, surrey and comparison aerial and satellite pictures with different time duration, surrey public morphology and sandy hill units and surrey regional winds, and location is entail of local geomorphological study and samplery of faces, performing granalometry, morphoscopy and inorganic tests. Based on the results of the study erosive winds in the region have northwest to west orient, and most important taking faces are riverbeds and arid streams of Esmail Abad, Roudhinar and Poor pastures of Esmail Abad. Also, faces sensitivity to blowy erosion using Eafer method is assessed from low to high.
