One of the most tremendous environmental crisis is the pollution of the cities that its' main cause is the human activities besides environmental factors. Modern thought toward urban development is that cities must be compatible with natural environment as far as possible and takes the step toward sustainability. Thus for access to a sustainable development in the cities, the deduction and control of air pollution can be of high importance important . So in the present research, the potential grading of air pollutant density in Tabriz by using ELECTRE method has been evaluated. The general framework of this research is based on gathering different informative layers (wind , crowd , land use, topography , queen space deficit , noise and vibration ,temperature ,inversion, connecting roads , volume of travels origin and destination) has been utilized as criterion and limitation factor.
Their valuing and weighing in the form of ELECTRE model as one of multi criteria analysis tactics in a functional contexts of the research subject was examined and used for the 10 districts of Tabriz.
Moreover for measuring the air pollutants' condensation, the data concerning to pollution monitoring stations of this city (Abrsan, Bagh shomal , Behdasht , hakim Nezami , Rah Ahan, Raste kauche station) have been used. Comparing the findings of the model and the data relevant with the stations indicate that the pollutant of PM10, SO2, Co are in critical and unhealthy condition in most of the stations especially in Raste Kauche, in which the crowd density and improper distribution of usages have more effect on the pollutants of this area, so that the most service and commercial uses which attract the population and vehicles during the day, ate located in district No.8 i.e. the central texture of the city. While the said district among the other districts has the most communication uses and the least green space, that such factors has caused the environmental instability and increase of pollutants' condensation. Based on the findings of this research, use of multi criteria analysis technique, in addition of increasing the accuracy and increase of the work speed, will increase the variety and causes the better quality of the results.
