Abstract:In order to deeply analyze the migratory level of VOCs in the atmosphere after emission and to evaluate its ability，a calculation method of VOCs migratory level in the correlated regions was proposed.Based on the forward trajectory simulation of HYSPLIT model，combining the meteorological information in the correlated regions，the evaluation index system was constructed.The dimensionless vertical and horizontal pull grade method was used to comprehensively and dynamically evaluate the five kinds of indexes representing the VOCs migratory level，and the VOCs migratory level index in the correlated region was calculated.The program of MATLAB was compiled to solve the problem of calculation involved in the method.Model validation showed that the method could realize the data difference analysis and spatiotemporal feature expression of VOCs migratory level in the correlated regions and its sub regions.By calculating the migratory level of VOCs in correlated regions，the actual pollution after VOCs emission could be measured，so as to scientifically guide the joint prevention and the control of VOCs pollution regions.
