Abstract
Abstract: In order to evaluate the interaction between regions due to the cross regional flow of VOCs(volatile organic compounds) under polluted weather, a dynamic risk assessment method of cross regional flow of VOCs is proposed by using Petri net modeling method. The migration paths of VOCs between multiple potential pollution sources and contaminated areas are determined by HYSPLIT model, and the relationship between each migration path is described by Petri net; the dynamic risk assessment method is defined, and the calculation of dynamic risk is integrated into the operation of functional Petri net; through case analysis, the dynamic risk assessment results of surrounding areas for Xi'an under polluted weather and the potential risk index of each pollution path are obtained. The research shows that under heavy pollution weather, the influence degree of each pollution source city on Xi'an is Baoji > Hanzhong > Xining > Lanzhou from high to low. This method provides a basis for evaluating the risk degree of potential pollution sources in the cross regional flow of VOCs.
