摘要:为了深入分析关联区域内VOCs在大气中的迁移水平与状况，评价其迁移能力，提出关联区域内VOCs迁移水平计算方法。基于HYSPLIT模型前向轨迹模拟，结合关联区域内气象信息构建评价指标体系，运用无量纲化纵横向拉开档次法对表征VOCs迁移水平的5类评价指标进行综合动态评价，计算关联区域内VOCs迁移水平指数，编译MATLAB程序解决计算量问题。模型验证表明：该方法能实现关联区域及其子区域内VOCs迁移水平数据差异分析和时空特征表达。该计算方法可衡量区域VOCs污染实际状况，为科学指导VOCs污染区域联防联控提供理论指导。

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.
