The invention discloses a photometry station coverage range analysis method based on region gridding lattice classification. The photometry station coverage range analysis method mainly comprises the steps of gridding a region to be measured according to latitudes and longitudes to acquire measurement data of geographical factors and meteorological environmental factors at lattices; drawing a graph according to the measurement data to obtain an altitude and the surface reflectance of the region to be measured, performing comprehensive analysis on the relevance of the geographical factors comprising the altitude heights and the surface reflectance at positions where the lattices are positioned, and performing lattice classification; analyzing and classifying the lattice data relevance based on the lattice classification result; determining a measurement range of a photometry station according to the lattice data relevance analysis and classification result. According to the photometry station coverage range analysis method based on region gridding lattice classification, the shortcomings of low stability, low energy conversion efficiency, low environment friendliness and the like in the prior art can be overcome, and the photometry station coverage range analysis method has the advantages of high stability, high energy conversion efficiency and high environment friendliness.
