Atmospheric pollution trend analysis method based on GIS (Geographic Information System) technology

The invention discloses an atmospheric pollution trend analysis method based on a GIS (Geographic Information System) technology, which comprises the following steps of: checking monitoring index numerical values of an atmospheric monitoring micro station in real time, dividing pollution grades according to different colors; according to different time nodes including past and future in a global range, performing three-dimensional visual expression of data of an atmospheric pollutant model and a wind field model, performing visual expression of data of an atmospheric monitoring micro station on the three-dimensional earth according to a time axis sequence, showing the pollution degree and the spatial distribution condition, and performing pollution traceability and trend analysis on the periphery of a severely polluted station. The atmospheric pollution trend analysis is realized in a mode of combining an automatic monitoring means and satellite remote sensing monitoring, the manual observation frequency is r
