The growth of the world’s urban population in the last century and the environmental changes resulting from urbanization and urbanism have led to unbalanced urban development and disintegration of natural habitats, which has led to climate change and the environment, increasing the frequency and severity of accidents and intensifying natural disasters like earthquake in cities. Therefore, it is essential for cities to rely on their potential to be sustainable and resilient to the world’s environmental change for sustainable life and growth. However, the spatial form and structure of cities may be immutable and inflexible, and its properties such as the size and pattern of urban development and the extent of distribution of urban facilities have a direct impact on social and economic changes and the urban environment and ultimately resilience. In the same vein, the main purpose of this study is to investigate the morphological changes in Qom over time on a large scale and the effect of these changes on the physical resilience of this city. This research is a combined research (quantitative and qualitative); to achieve the objectives of the research, the qualitative data have been examined through GIS and satellite images, and also the quantitative data have been examined through statistical analysis using Shannon and Holdern Entropy Models and Gini and Moran coefficients. The results of this study indicate that the uncontrolled growth of population and body of Qom in recent decades, along with the concentration of urban facilities in certain urban areas, causes scattered and isolated urban development and unbalanced morphological changes in Qom metropolitan scale, particularly in areas 1, 3, 5 and 8, which has finally reduced the flexibility and physical resilience of Qom.
