Soil pollution prediction method and system for heavy metal stable pollution source

The embodiment of the invention provides a soil pollution prediction method and system for a heavy metal stable pollution source, and the method comprises the steps: dividing a target pollution regioninto a plurality of grids with preset sizes, and building a cellular automaton model; for each grid at the current moment, enabling the cellular automaton model to calculate the probability of pollution of each grid at the next moment according to the probability of pollution of a plurality of neighborhood grids of each grid; repeating the process for a preset number of times, and predicting theprobability of pollution of each grid at a preset moment. According to the embodiment of the invention, a cellular automaton geographic space simulation framework is adopted, and the probability of pollution of the grid at the next moment is predicted through the probability of pollution of neighborhood grids around the grid, so that dynamic simulation of soil heavy metal pollution risk diffusionis realized, and the spatia
