The invention provides a crop loss assessment method based on multi-stage image comparison, and relates to the field of crop disaster loss assessment. The method comprises a satellite imaging system,a signal base station, a multispectral acquisition device and an image comparison terminal. The satellite imaging system is used for periodically shooting multispectral imaging pictures and high-definition imaging pictures and transmitting relevant information to the image comparison terminal through the signal base station, the image comparison terminal receives the relevant information and makesa comparison map, and the comparison map is used as an original comparison file for judging crop damage. A worker selects a sample area according to the loss reporting area. The multispectral acquisition device acquires a high-definition image and a multispectral image of a sample area, an agricultural expert evaluates the rating of the sample area according to an evaluation method and inputs therating into the image comp
