| 摘 要： | 为了弥补A—P值法的不足，本文以A值法和SSIM模式为基础。提出了一种合理分配城市面源SO2允许排放总量的方法。该方法将A值法计算出的面源SO2允许排放总量作为一个约束条件放入SSIM（Source Strength Inversed Model）模式，调整该模式中各组源强的分担率，直至模式反演出的城市控制区各网格内的面源允许排放量之和与约束条件相等为止，此时模式输出的网格面源SO2允许排放量就是城市控制区内面源SO2允许排放总量的分配结果。应用该方法对石家庄市面源SO2允许排放总量进行网格分配，并采用美国工业源长期浓度复合模式（ISC3LT）对石家庄市SO2总量控制效果进行检验。结果表明：采用该方法分配面源SO2允许排放总量，可保证城市总量控制区内各网格上的SO2浓度值均满足国家标准。

| Abstract: | In order to improve the A-P value method,a rational method for distributing permissible sulfur dioxide(SO_2) emission to urban area sources is put forwarded.The permissible SO_2 emission calculated by the A-value method was added to SSIM(Source Strength Inversed Model) as a restriction condition to adjust the sharing ratio of different pollution sources.When the calculated sum of permissible area source emission in each grid for urban control areas is equal to the restricted value,the model output is the distributing result for permissible emission in urban control areas.It was used to calculate the grids' permissible SO_2 emission in Shijiazhuang,and the effectiveness was verified by using ISC3LT.The results show that with the method,SO_2 concentrations can be controlled within the National Standards on the grids of the control areas(urban areas). |
