Over the past few years, lands of many cities in Iran, especially marginal lands, have been repurposed due to the urbanization trend and need of citizens for new housing, turning this city parts into lands for construction. Given the facing of Mahshahr city with the phenomenon of immigration in the past years, significant changes have been observed in urban land use of this area. The research aimed to evaluate land changes in Mahshahr city during 1966-2011. To learn about the type and amount of changes, the Landsat images of TM, ETM, OLI/TIRS and the demographic changes of this city in the period of 1956-2011 were assessed. After image enhancement, fuzzy methods based on compliance intensity (Fuzzy Artmap) and comparison after classification (Crosstab) were used to detect and evaluate the changes. According to the results of the study, no significant changes have been observed in the area of green spaces and pastures of Mahshahr during 1976-1986; when the most immigrations to this city occurred. However, given the growth of urban space during 1986-1996, the area of green spaces and pastures significantly decreased. Therefore, the green spaces and pastures of this city reduced due to population growth with a delay. Nevertheless, there has been an increase in the green space area of the city during 1996-2006 despite the population and urban area growth.
