Uncontrolled urban growth has several negative effects on our surrounding natural environment. One of the main problems is the change of valuable natural and agricultural lands to urban areas. This study aimed to extract the past land use changes and predict future changes in the southwestern regions of Isfahan province over 30 years using a hybrid model of cellular automata (CA) and fuzzy logic. Landsat 7 ETM+ and OLI Landsat 8 images for 2003-2013-2022 were used together with topographic and geological maps of the region as data. Satellite images were classified and validated into five land uses classes including agriculture, forest, urban, water and barren lands. The CA model then predicted and produced land use maps for 2023 and 2033. Next, to evaluate the suitability of the projected land use in each location, the selected parameters were mapped based on their nature and role in the study area using the different operators of the fuzzy model. Results showed that 35 % of the study area is suitable for urban growth and more than 36 % of the project urban land uses are located in these areas. In contrast, 54 % of the project urban land uses are located in the class of moderate suitable, and finally about 10 % the project urban land use is located in the class of not suitable, which should be the main concern of the local government. Integration of these two models creates an accurate understanding of future urban changes for decision makers.
