Abstract :
According to desert habitation sensitivity and for optimum management of these areas and zone, it is essential that all effective factors in the habitation situation are investigated. Therefore in this research the relationship between wind erosion as a climatic-anthropogenic common phenomenon in desert area and under protected areas is studied in Yazd Province. By estimating the rate of wind erosion in such area, the capability of environment for providing appropriate conditions for animal species subsistence can also be estimated. This research has two parts: first, using of iso-erosion map and under protected areas map in order to determine of affected regions in every zone. Second, determination of habitation value of four under protected areas on the basis of food, water and security as three variable factors. Finally the correlation of the value of each habitation with the area of the regions was determined. The results showed there is strong correlation between two mentioned factors (r = -0.87). It means that effective factors of the increase of wind erosion amount affect on the quality of protected habitation and habitation value reduce proportional with the increase of the area of affected regions.
