| description | In order to avoid subjectivism, catastrophe theory functions were used to the integration of different variables in the context of geographic information system. Decrease in decision making uncertainty during weighting process and to some extent in classification uncertainty, high flexibility in type and number of variables, and consideration of spatial differentiation of variables are the most important advantages of this model. The comparison between the results of this model and field and geographic facts indicates high efficiency and validity of used model. Feasibility of spatial-physical development of Tabriz using catastrophe theory showed that because of special geomorphologic, geologic, soil and hydrologic conditions, there are not suitable zones for the spatial- physical development in the surrounding of the city. The best zones for outer development of the city is located in the southwest of the peri-urban areas between Tabriz and Sahand new town. Although, the physical development of the city in these zones- in the form of towns- will require high cost for the preparation of lands. Therefore considering environmental unsuitable conditions of city’s surrounding, it would be better to plan the physical-spatial development with regard to the city’s inner potentials (such as renovation of old texture). |
