Spatial Analysis and Ranking of Noise Pollution in 15 Regions of Isfahan Metropolis

Noise pollution, as one of the lesser-known environmental pollutants, has affected the residential areas of the country's metropolises. One of the main reasons for this problem is the lack of attention to spatial factors affecting noise pollution, lack of evaluation studies and insufficient familiarity with the methods of assessing the effects of development measures on noise pollution in the urban planning system. This study aims to spatial analysis and ranking of noise pollution in 15 regions of Isfahan metropolis. In this regard, the mixed research method (quantitative and qualitative) has been used and the required information has been collected through library and field methods. In addition, spatial analysis method in ArcGIS software was used for data analysis and Analytic Hierarchy Process (AHP) method in Expert Choice software was used to weight the indicators. The results indicate that the spatial distribution of noise pollution in the regions of Isfahan is unbalanced. As in the central regions 1, 3 and regions 8 & 10, mainly due to the existence of busy passages and non-observance of construction privacy for them, the impact of noisy land uses, population concentration and compactness, noise pollution is in a more unfavorable situation than other regions. Among the most important solutions to deal with this issue, can be mentioned to the observance of construction privacy for busy passages and noisy land uses in urban development plans, transfer of workshops and terminals from residential areas to non-sensitive areas and reducing congestion and increasing the complexity of designing new patches.
