Atmospheric pollution source accurate traceability method and system based on gridding data

The invention relates to the technical field of atmospheric pollution monitoring, in particular to an atmospheric pollution source accurate tracing method and system based on gridding data. The invention aims to solve the problems that in the prior art, monitoring stations lack pertinence, factors such as pollution source distribution and prevailing wind directions in a region are difficult to fully consider, so that the temporal-spatial resolution of monitoring data is insufficient, and an existing pollution tracing method mainly depends on monitoring data of a single station or on-site patrol of a few grid members, so that the monitoring efficiency is low. And accurate traceability is difficult to realize. According to the method, gridding micro-station monitoring equipment is deployed through a differentiated point location layout scheme, a pollution high-value area is identified according to real-time monitoring data, a spatial distribution range of a suspected pollution source is delimited, a pollutant t
