Abstract

The embodiment of the invention discloses an atmospheric pollution source analysis method and device, electronic equipment and a storage medium. The atmospheric pollution source analysis method comprises the following steps: dividing each source class in an emission list of an area into sub-source classes; simulating the emission and diffusion processes of sub-source classes in each source class in an emission list of an area by using a CALPUFF model to obtain a pollution contribution ratio of each sub-source class of the area to a receptor point; carrying out source analysis of a CMB model onthe region by utilizing the source component spectrum and the receptor component data to obtain pollution contribution proportions of various sources of the region; and coupling the pollution contribution ratio of each sub-source class to the receptor point obtained by simulation of the CALPUFF model with the pollution contribution ratio of each sub-source class of the region obtained by the CMBmodel, and establishing a refined source analysis result.

Description

technical field [0001] The invention relates to the field of air pollution detection, in particular to an air pollution source analysis method, device, electronic equipment and storage medium. Background technique [0002] At present, there are three main methods for source apportionment of ambient particulate matter: receptor model, source inventory analysis, and air quality model. CALPUFF conducts spatial simulation based on emission source data, and is a widely used mesoscale air quality model; CMB conducts source analysis based on PM2.5 component data from receptor point monitoring or sampling analysis, and is one of the most widely used receptor models . [0003] Some studies abroad have been carried out very early, and the research comprehensively uses the air quality model and the receptor model to analyze the source of a certain receptor point. The two models are compared and verified with each other. For example, Amit M et al. (2005) used the CMAQ and CMB models t...
