Abstract
The present study attempts to explain the spatial patterns of Qom city in the last 50 years. This research is applied in nature and descriptive-analytical in terms of method and based on remote sensing data. First, the images of 1972, 1986, 1997, 2008 and 2021 were obtained from Landsat 5 and 8 satellites using MMS, TM and OLI sensors. Then, using ENVI software and the supervised classification method, they were converted into land use maps in four classes: urban, agricultural, mountain and water. Then, these maps were prepared using ARC GIS PRO software to enter into Fragastas software, and in the next step, they were called to this software for land surface analysis. In the next step, these maps were analyzed using spatial metrics (PALAN-PD-NP-LSI-LPI-AWMFD-ENN-MN). In the last stage, by calling these metrics in the Shannon entropy model, an overall picture of the spatial growth pattern of Qom city in the last 50 years was obtained. Also, to check this goal, whether the city of Qom has grown and developed in the desired direction or vice versa after preparing the layers of slope, height, land use, fault, river, village, city and road, which are the most important factors in urban growth and development.
