Abstract

The invention discloses an urban area motor vehicle tail gas contaminant concentration distribution prediction method. According to the method, firstly, relevant information of a region to be tested is collected; a motor vehicle tail gas contaminant concentration association graph is built; the edge weight of the motor vehicle tail gas contaminant concentration association graph is determined; then, the motor vehicle tail gas contaminant concentration distribution of unknown nodes in the motor vehicle tail gas contaminant concentration association graph and the average uncertainty degree of the motor vehicle tail gas contaminant concentration association graph are calculated; the average uncertainty degree is minimized to obtain the motor vehicle tail gas contaminant concentration prediction distribution of the unknown nodes. The method provided by the invention well solves the problem of prediction capability of the motor vehicle tail gas contaminant concentration distribution in anyposition of a city, and can provide the effective help for supervision departments to monitor the urban area motor vehicle tail gas contaminant concentration distribution.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and relates to a method for predicting the concentration distribution of pollutants, in particular to a method for predicting the concentration distribution of motor vehicle exhaust pollutants in urban areas. Background technique [0002] Exhaust gas emitted by motor vehicles contains a large amount of harmful gases. As the main source of air pollution, these harmful gases are the root cause of environmental degradation and severe smog. Since the concentration distribution of motor vehicle exhaust pollutants is uneven and dynamic, and it is difficult for air monitoring stations and monitoring equipment to cover every area of ​​the city, in order to effectively supervise the emission of motor vehicle exhaust pollutants, it is necessary to predict the motor vehicle exhaust emissions of the entire city. The concentration distribution of exhaust pollutants can identify high-concentra...
