The invention provides a file information matching
system based on an emission right, and the
system is characterized in that the
system comprises a receiving module which is used for receiving an emission right application file submitted by an enterprise; based on the to-be-declared
pollutant information in the application file, taking the emission position as a target detection area, obtaining emission information of the target detection area, and based on the collaborative
hazard knowledge graph, performing
correlation analysis on the to-be-declared
pollutant information and the emission information to obtain a correlation result of the to-be-declared
pollutant information; identifying whether a collaborative
hazard risk that the
environmental hazard may be amplified due to coexistence of different pollutants exists or not, and generating a
risk level;
background data of the target detection area are acquired, the
background data comprise area environment capacity data and pollutant consumption rate, to-be-declared pollutant information is acquired, and an environment cost influence value is generated; and obtaining the environmental cost influence values of the plurality of application files in the target detection area, carrying out priority
ranking, and carrying out matched distribution of the
pollution discharge right according to a
ranking result and the
risk level.
