description The invention relates to the field of dangerous rock and rockfall migration trajectory simulation, in particular to a dangerous rock and rockfall migration trajectory simulation method based on a three-dimensional GIS scene, and the method comprises the steps: carrying out the region division processing based on a GIS system, and obtaining a first region; acquiring elevation data of the first area; utilizing the elevation data of the first area to obtain a first area terrain model; according to the first area terrain model, dangerous rock falling rock migration trajectory simulation processing is completed, in any GIS system, dangerous rock falling rock migration trajectory simulation calculation can be rapidly completed, different parameters are used for multiple times of calculation so as to meet the motion characteristics of different working conditions in reality, and therefore the dangerous rock falling rock influence range is determined. Meanwhile, a calculation result can be further analyzed and proces
