Air pollutant monitoring method and device based on large-range ground monitoring stations

The invention provides an air pollutant monitoring method and device based on a large-range ground monitoring station. The method comprises the following steps: acquiring ground air monitoring station data and concentration monitoring data in a target area; assigning geographic attributes to the ground monitoring stations and calculating the missing rate; interpolating the missing monitoring data according to the geographic attributes of the ground monitoring stations; performing spatial scale segmentation on the monitoring data according to geographic attributes of the ground monitoring stations; performing time scale segmentation on the monitoring data according to the time interval, then fusing the monitoring data into a multi-scale data set, and then performing merging and filtering processing; and performing statistical index calculation and analysis on the combined and filtered multi-scale data set to obtain distribution data of the air pollutants. According to the method, the problems of data processin
