Ecological capacity assessment for sustainable urban development, using MADM and GIS (a case study of Shahriyar City)

Ecological capacity assessment is an indispensable tool for achieving sustainable urban development. As urbanization continues to reshape the world, these assessments will play an increasingly vital role in fostering environmentally conscious and resilient cities. Shahriyar city with an area of ۳۶۰ km۲ is located in the west of Tehran province. Due to the growing population of this city, environmental assessment studies are necessary for urban development. In this study, the multi-attribute decision-making method (MADM), and GIS were used for the ecological capacity assessment of Shahriyar City. First, the ecological and socioeconomic resources of this city were identified. In the second step urban development criteria were extracted from different sources. Then the main urban development criteria of Shahriyar city were screened using the Delphi method. Some criteria including topography, water resources, soil, and socio-economic were selected as the main data layers. The weight of each layer was calculated via the AHP tool. Finally, all of the layers were overlaid in GIS based on their weight, and the map of land suitability for urban development of the city was plotted. Then the final land suitability map of Shahriyar was prepared into ۹ classification codes. The result shows that code ۹ with an area equal to ۵۶.۱۱ km۲, which is ۱۸.۱% of the Shahriyar area, due to its unity and the suitable degree of the slope, direction, distance from the limiting factors such as faults, rivers, and industrial centers is the most appropriate area for urban development in Shahriyar city.
