Satellite images taken from Landsat 8,7 and 5 satellites and for three time periods (1987, 2000, 2016), which were provided by international references. All map corrections were performed in ENVI 5.3 and ARC GIS 10.2 software. The results of this study showed that in the first period of the study (1987), the largest area of land use was for Rain fed land with an area of 1558.63 Km2 and the smallest area was the Residential area with an area of 15.77 Km2. Also in the second period (1987-2000), the largest area of land use was for Rain fed land with an area of 1465.74 Km2 and the smallest area belonged to residential land with an area of 19.44 Km2.Whereas in the third period (2000-2016), the largest area of land use was Irrigated lands with an area of 1054.60 Km2, and then the uncoated lands with an area of 1050.62 km2 and the smallest area related to Residential land with area 22.51 Km2.
