The physical development of cities is a dynamic and continuous process, during which the physical limits of the city and its physical spaces in vertical and horizontal directions are increased quantitatively and qualitatively, and if this process is rapid and unplanned, it causes an unbalanced physical development of spaces. It becomes urban and as a result it will face many problems in urban systems. Therefore, the goals of this research are to analyze land suitability for the purpose of urban physical development with the approach of environmental considerations. The research method is applied according to the purpose and descriptive-analytical in terms of its nature and method. The investigated criteria include 11 environmental components (height, slope, direction of slope, distance from the service area of the city, soil erosion, geology, distance from rivers, distance from fault, distance from rural areas, land use and distance from It is the road. To evaluate and analyze land suitability for physical development, various multi-criteria decision-making techniques (MCDM) have been used. Excel, GIS, IDRISI and Google Earth pro software were used for data analysis and map drawing. The results of the research showed that parts of the southern, southeastern, southwestern, and northeastern parts of the studied area are the most suitable places for the physical development of Oshnavieh city. The main reason for this choice was the appropriate slope, the distance from the river and the fault, etc. Finally, two priority ranges (A and B) were proposed for the physical development of the city for the coming years, which can be used in accordance with the needs in the phase of continuous and discontinuous urban development to develop and create residential settlements as an option, compared to other options. Others should be considered.
