The effect of different housing textures on air pollution intensity: Erzurum case.

Air pollution is one of the most important problems that threaten life today. Different housing textures in the city were examined in terms of air pollution values (emission values) and geographical variables that trigger air pollution (pressure, altitude, wind, temperature) and physical variables (natural gas consumption, coal consumption and Sky View Factor). Spatial analyzes of the variables were done with Arcgis. SPSS was used for statistical analysis. Correlation analysis was used to understand the difference between housing patterns variables, Kruskal Wallis to understand the difference between housing patterns, and Posthoc – Games Howell analysis at 95% confidence level to reveal which parameters were different. Block-type housing pattern is significantly more dense than other housing patterns in terms of emission values and pressure values, and has a significantly more intense value in natural gas and coal consumption than other housing patterns, except shanty housing. Gated community type housing texture has a significantly more intense value in terms of wind speed than other housing patterns. As a matter of fact, the wind speed was found to be less than 3 m/s. The shanty housing pattern has a significantly more intense value than other housing patterns in terms of altitude and fuel consumption. Detached house texture has a significantly higher value of O3, temperature and SVF than other housing patterns. Considering the urban transformation areas in Erzurum, it is clear that local governments, city planners and landscape architects should produce site-specific urban design proposals, taking into account the natural conditions.
