摘要
通过实例,对AERMOD在大气环境影响评价中的应用进行讨论。根据2007年1月～12月达州市地面和高空气象数据、项目所在地的地形资料,应用AERMOD预测模型建立了空气扩散模型,对工程的大气环境影响进行了预测与评价。结果表明:AERMOD空气扩散模型实现了评价区域二维地形向三维地形的可视化转变,预测浓度分布能够反映出污染源分布和气象场变化以及地形等对大气污染物迁移和扩散的影响。
Application of AERMOD model on impact evaluation of atmospheric environment was discussed through examples in the paper.The atmosphere model(AERMOD) was built according to the topography,surface and upper data from Dazhou weather station to forecast and assess the impacts of atmospheric environment.The results showed that 2D terrain could be transformed to 3D though AERMOD processes,and atmosphere forecast concentration could reflect the pollutant distribution and the impact of terrain and meteorological field on air pollutant transfer and diffusion.
