The study of environmental factors affecting the growth and development of rural and urban areas leads to determining the optimal aspects of future urban development and the potential of the environment for spatial expansion. In this study, land suitability for physical-spatial development of Shahmirzad village in the north of Mahdishahr, Semnan province, where the settlement of dwellings and uses in its geographical environment (Chakeh river basin) does not have relative morphodynamic stability, based on ten criteria in four proposed areas The descriptive-analytical method was performed with the aim of providing location and appropriate solutions for Shahmirzad's future development, and the weighting of related criteria and parameters was done from AHP hierarchical model and Makhdoom model with the help of experts' knowledge and Chois export software. Based on the studies, it was concluded that different urban geographical areas of Shahmirzad (Shahmirzad North Shahmirzad South, Shahmirzad East and Shahmirzad West) are not quantitatively and qualitatively homogeneous in terms of application and distribution of environmental methods and the distribution of residential spatial in Relation to indicators such as people's inclinations, height and slope of land, situation in relation to natural hazards, distance from agricultural lands and gardens, distance from surface water, area, land ownership factor (endowment and government land), purchase cost, preparation cost And the situation with respect to heterogeneous uses) is not commensurate. Meanwhile, economic indicators such as purchase cost and preparation cost and land ownership factor accounted for more than 50% of the share of the city's expansion to high-risk areas in terms of natural hazards (floods, landslides and earthquakes) and destruction. , Capture fertile gardens and change land use. Any development must be done in accordance with ecological constraints, while purposeful development is to be formed between the four areas for the future development of Shahmirzad and based on the horizon of sustainable development. After evaluation and zoning, it was found that the eastern area (eastern Shahmirzad area and around Kolahdooz town) has more environmental potential for the future sustainable development of Shahmirzad space than the west, north and south of the city.
