Abstract
The mutual effects of humans and the natural environment always directly and indirectly cause land use changes, which lead to many environmental problems and endanger the life of the planet; Therefore, it is necessary to know the changes and the factors affecting them in order to continue life and reduce land use changes to overcome the problems. The current research is of applied type and in terms of its nature, it has an exploratory approach. In this research, satellite images of 1993-2003-2013-2023 and ENVI, ARCGIS and Google Earth software were used to identify land use changes in 5 land use classes of the city (man-made), barren lands, agricultural lands, garden lands and water lands have been used. The results obtained in the studied area during the last three decades during the years 1993-2023 from 26768 hectares of urban lands in Urmia and outside its boundaries show that urban lands (man-made) have always increased by 3744 hectares, lands Barren land decreased by 2838 hectares, agricultural lands increased by 2204 hectares, garden lands decreased by 5764 hectares, and water lands (river bed) have water seasonally due to the construction of Silvana Dam. Using the fuzzy Delphi method, 6 factors of population, wealth, technological progress, political economy, political structure, attitudes and values (culture) were identified as the main factors of urban land use changes in Urmia, and the first three factors are the main factors.
