Research on buildings impacting on aerosol diffusing in urban area using remote sensing

Employing remote sensing method to interpret the building volumetric ratio and aerosol status in Guangzhou, China. The relation between them and identified characteristics of their spatial distribution was analyzed. Results showed that building density and aerosol status are strongly correlated. It is indicated that the resistance of building to aerosol diffusing is one of factors influencing air pollution in urban area. On the basis of calculated results, building voluminous ratio of 5.6 is taken as the threshold impacting on aerosol diffusing, so the building voluminous ratio of Guangzhou should be limited to less than 5.6 in order to alleviate air pollution.
