The results showed that from 1997 to 2017 the area of residential use and water resources decreased and the area of agricultural use and bayer lands increased. So that increased of the residential use of 75373.11 hectares with an area of 14675.04 and water resources with an area of 23918.31 hectares with a total area of 248.76, the water resources of this city have decreased by 32/58 percent over the course of twenty years, and the Bayer lands from 66717150 in 1997 to 1820,86 in 2017, and agricultural use has increased from 13,30029 to 38388 in area.
