Method and device for acquiring resident space carbon emission

Abstract

The invention provides a method and a device for acquiring space carbon emission of residents, and belongs to the technical field of environment monitoring. Firstly, POI data and night light remote sensing data of a target area are obtained, grid division is carried out on the target area, the importance degree of each land class in each grid is determined according to POI data of each land class of each grid, and then a night pure light value of a residential land class under each grid is calculated based on the obtained night light remote sensing data; and determining the carbon emission of each grid according to the total resident carbon emission in the target area and the proportion of the night pure light value of the resident place class of each grid in the target area. Compared with the prior art, the method has the advantages that a more accurate resident carbon emission spatial distribution pattern is obtained through the extracted night pure light values of the resident places, the influence of night light of other places is reduced, the precision of a resident carbon emission spatial distribution result is improved, and a more accurate data source is provided for subsequent low-carbon research.

Description

technical field [0001] The invention relates to a method and a device for obtaining carbon emissions in residential spaces, and belongs to the technical field of environmental monitoring. Background technique [0002] Global warming caused by increased carbon emissions has profoundly affected people's lives and health. In order to cope with the serious consequences of global warming, countries around the world have begun a series of actions to curb climate warming and reduce man-made carbon dioxide emissions. Residential carbon emissions are an important source of carbon emissions, and the study of the spatial distribution pattern of residential carbon emissions is of great significance for low-carbon development and low-carbon construction. Night lights can objectively reflect the status of human social production and living activities. Night light data have been widely used in the research of urban development, natural environment, and social and economic activities. [0...
