In the present research land use changes modeling in the Urmia city is considered in order to detect changes in agricultural lands. In this regard, Landsat satellite images were used and then the object base processing satellite images was performed by applying the process segmentation and in the next stage, the optimization of scale segmentation and image analysis to its constituent elements, the object basic algorithms according to the physical condition, geometric of each land-use classes were used. During images processing in addition to spectral data, the data in the form of homogeneous, shape and texture (GLCM) were used for land use extraction. The results show that the Urmia city had so many physical expand in the past 31 years so that its area has increased from 7.43% of the total study area in 1363 to 30.75 in 1394. This increase was rectify by the reduction of agricultural lands so that large amount of agricultural lands have been used for construction purposes which has caused land degradation, particularly fertile lands in this area, particularly within the Shahr chay river, Mahabad road, Sero road, Darya road and the road of Salmas.
