The invention discloses an atmospheric pollution three-dimensional monitoring and data processing method based on a fixed-wing unmanned aerial vehicle, and the method comprises the steps of: employing the fixed-wing unmanned aerial vehicle to carry a gaseous pollutant detection module, a wind speed and direction collection module, a temperature and humidity module, a GPS positioning module, and a wireless data transmission module, and flying in the to-be-monitored area according to a height increasing mode and detecting the gaseous pollutants on the route, so that the defect that the atmospheric pollutants at different heights cannot be detected at the same time is overcome. According to the method, the factors of temperature, wind speed and humidity influencing the measurement of the atmospheric pollutant concentration are substituted into the atmospheric pollutant concentration correction formula, the correction coefficient is obtained by using the radial basis function neural network training method, the monitoring precision is improved, and the proposed atmospheric pollutant concentration correction formula can be used for detecting the concentration of various atmospheric pollutants. The method is used for observing and researching the three-dimensional space dynamic change rule of pollution source emission, and achieves the evaluation and prediction of the influence of the pollution source on the air quality of the surrounding environment and the monitoring of the abnormal emission of the pollution source.
