Assessment and Optimization of Urban Physical Growth in in Order to Maintain Vegetation and Agricultural Land (Case Study: City University)

Increase in urban population changes agricultural lands to residential, commercial and industrial uses. These changes have unfavorable consequences including loss of vegetation cover on the urban environment. Ambient temperature and high-quality agricultural lands have been destroyed. In In this regard one of the strategies that optimizes the physical fabric of urban and reduces environmental damage is the use of modern techniques of remote sensing which plays an effective role in the management and the improvement of urban land use. This paper aimed to evaluate and optimize physical growth of Urmia to maintain vegetation and agricultural lands developed. Therefore, changes in land use Urmia, between 1985 and 2011 were calculated. Reviews indicate a sharp decline in agricultural lands and orchards in the area. So as using AHP descriptive model we found that in order to satisfy the requirements of urban development five categories should be considered: From very suitable to very poor groups. The results showed that over 21.5ha of the area, (i.e. 5.08%) have suitable conditions for the intended purpose.
