Development Model of Oxide of Nitrogen Concentration and Land Use Characteristics in Bangkok Area

摘要

In this study, NOx concentrations and land use characteristics were correlated to develop a Land Use Regression (LUR) model for application in Bangkok Metropolitan, Thailand. Measured NOx concentrations data from thirteen air quality monitoring stations located in Bangkok area were analyzed to develop LUR equations. Land use data obtained from site survey method and was characterized into the following categories, i.e., building with 1-2 floors, building with 3-5 floors, building with over 5 floors, green area, road area, space area and open water. The results showed that NOx concentration positively correlated with percentage areas of building 3-5 floors, building >5 floors and road area while NOx had a negative relationship with building 1-2 floors, green area, and space area. The obtained regression model was able to predict 89% of the variation in NOx concentration.
