Characterization of Construction Dust Emission from Urban Perspective Based on Remote Sensing Image:A Case Study of Guangzhou
As urbanization continues,construction-related dust has emerged as a significant contributor to urban air pollution.A comprehensive evaluation of the environmental impact of construction dust necessitates an understanding of the pollution discharge from an urban perspective.Consequently,this paper proposes a construction dust emission inventory construction method from the urban perspective,which combines remote sensing image interpretation and the emission factor method.On this basis,a particulate matter emission inventory of construction dust sources in Guangzhou in 2020 is established,and the emission characteristics of the study area are analyzed using a 2km×2km grid distribution.The findings of this research provide a crucial data foundation for high-resolution pollutant diffusion simulations and environmental impact assessments.They also offer a macro perspective for observing construction pollution,which can be utilized by the government to monitor and control pollution from an urban perspective.
