摘要
为给予环境影响评价工作提供重要理论依据,文章利用AERMOD模型,研究了不同点源和面源参数对大气预测结果的影响。结果表明,同一点源,出口烟气温度越高或烟筒几何高度越高,最大地面浓度贡献值越小,且温度对结果影响更大;同一面源,平均释放高度越高,最大地面浓度贡献值越小。
In order to provide an important theoretical basis for environmental impact assessment,the AERMOD model was used to study the effects of different point source and surface source parameters on atmospheric prediction results.The results show that at the same point source,the higher the outlet flue gas temperature or the higher the chimney geometry height,the smaller the contribution value of the maximum ground concentration,and the temperature has a greater influence on the results.For the same surface source,the higher the average release height is,the smaller the contribution value of maximum surface concentration is.
