区域大气污染物日均浓度不同计算方法的比较

Comparison of Calculation Methods for Daily Average Concentration of an Atmospheric Pollutant in a Zone

在计算区域典型日大气中ＳＯ２日均浓度时，对点源采用高斯烟流模式和烟团模式；对面源分别采用后退点源模式和面源积分模式。计算结果均与实际的监测值比较接近。

For the calculation of daily average concentration of SO2 in the atmosphere of a zone during a normal day, Gaussian plume and puff models are used for point source, backward point source model and area source integral model are separately used for area source. The calculation results are close to the actual monitoring values, but calculation precision for area cource integral model is higher than that for backward point source model.
