摘要 SCREEN3作为大气环评导则推荐的估算模式在大气环评工作中得到广泛应用,而SCREEN3模式对复杂地形的处理有一定局限性。AERSCREEN模式在气象数据处理、地形数据处理以及建筑物下洗等方面做了较多改进。通过案例在不同预测情境下的设定,对比地形因素对污染物落地浓度预测结果的影响。结果显示:在调用地形文件的情况下,污染物落地浓度变化范围增大、波动明显,污染物落地浓度与距离的相关性减弱,但整体趋势随着离源距离的增加,落地浓度是分级下降的。测算案例周围地形整体呈东高西低、南高北低,AERSCREEN模型调用地形参数模拟得出,项目排放的污染物受东北方及东南方山体阻隔,在山前聚积效应明显。 As the recommended screening-level air quality model in Guidelines for Environmental Impact Assessment--Atmospheric Environment (HJ 2.2-2008) , SCREEN3 has been widely used so far. However, SCREEN3 model has some limitations on complex terrain parameter processing. AERSCREEN has made more improvements in meteorological parameter processing, terrain parameter processing, and building down wash. Based on the case comparison in different forecast scenarios, the impact of terrain parameter on the prediction of ground level concentration of pollutants was studied. The results showed that in the ease of adopting terrain processing, the variation range of ground level concentration increased and fluctuated obviously, and the correlation between ground level concentration and distance was weakened, while the ground concentration graded down with the increase of the distance from the source. The project location had lower terrain around the whole west than the east, the north than the south. The AERSCREEN model simulation results showed that the pollutants were significantly affected by the northeastern and southeastern mountain blocks, and the pollutants accumulated in the piedmont.
