Abstract

Abstract: To solve the cascade transmission evaluation of ecosystem damage caused by dust migration in mining area, the migration network is constructed by dust migration path, and the potential hazard source path is identified. The definition of Petri-net simulation model of ecosystem damage with cascade propagation (PN-EDCP) is given, and the general method of abstracting migration paths network into a Petri net model is expounded. By introducing the concepts of attributes and methods of place objects into Petri net model, the real meaning of the model is clear, and the ability of describing and analyzing the logical relationship between ecosystem objects and the damage cascade transmission path can be obtained, which can visually show the damage process of mineral dust migration to ecosystem. In the case study, based on the simulation analysis results, the damage degree trend and the related cascade path are discussed intensively.
