Evaluation of Urban Development Capability With Multi Criteria Decision Making Approach (Case Study: Qaen City)

Qaen City is the administrative and political center of Qaenat County in south Khorasan province. Since the use of land is without consideration of ecological potential in addition to environmental degradation, it will also be diverted from sustainable development. Therefore, it is necessary to determine the ecological capabilities of the city for its urban development. This research was conducted with the aim of determining suitable locations for urban development in the Qaen City, South Khorasan Province. For this purpose, using multi-criteria decision making methods (MCDM), the weighted linear combination method was chosen due to the possibility of standardization and assigning different weights to the criteria and in geographic information system based on observations of the natural environment (6 criteria), city ecological potential was evaluated within the limits of the city's final privacy. The results indicate that From a total of 225.12 square kilometers, the area of study area, 50.21 square kilometers is suitable for urban development And 7.26 square kilometers of moderate proportion and 1.95 square kilometers have a small proportion of urban development And an area of 165/7 square kilometers was considered inappropriate for the development of the Qaen City, and has no urban development capability.
