Abstract
Today, air pollution of large cities has caused major crises in economic, social, environmental and physical development. So that this issue has become the first priority for urban planners in order to curb the problem. Investigating the effects of urban form on air quality has been considered in both experimental and theoretical research. Arak metropolis is unhealthy especially for vulnerable groups due to the presence of many sources of air pollution in more than half of the days of the year and now it is one of the eight polluted cities in the country. The present study attempted to evaluate the impact of city form indicators on the pollution of the city. The research results showed; There has been a significant relationship between the city form index and the dependent variable (air pollution index) at the 95% level. So that the R2 value obtained from the spatial analysis of the city form index on SO2, showed 72% and the influence of the city form on the production of this pollutant. The intensity of the effect is greater in zones 2 and 3 of Arak city. This study explored the regional form and air pollution in a city where the concentration of industrial plants exacerbated environmental situation. So urban planning and policies should be formulated in accordance with the city function and industrial structure of Arak metropolis.
