摘要: 为了解决矿尘迁移致矿区生态系统损害级联传播评价问题,采用矿尘迁移路径构建迁移网络,明确潜在的危害来源路径,给出了生态系统损害级联传播Petri网仿真模型(PN-EDCP)的定义,阐述了将迁移路径网络抽象为Petri网模型的一般方法。通过向Petri网模型中引入库所对象属性与方法的概念,使得模型真实含义清晰,具备对生态系统对象间逻辑关系及损害级联传播路径的描述和分析能力,能够将矿尘迁移现象损害生态系统的过程直观展现出来。在实例研究中,使用PN-EDCP模型完成了仿真分析,并对损害度变化趋势及与之相关的级联路径进行了深入讨论。

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.

Key words: dust migration, ecosystem, damage degree, cascade propagation, Petri net
