AERSCREEN模型在大尺寸面源预测中的参数影响分析

Parameter Influence Analysis of AERSCREEN Model in Large-scale Area Source Prediction

AERSCREEN模型作为《环境影响评价技术导则大气环境》(HJ 2.2-2018)中推荐的估算模型在近年的环评工作中得到了广泛应用。通过某整车制造项目涂装车间面源案例,采用正交试验法,分析在大尺寸面源估算预测过程中,初始垂向扩散参数、土地利用类型、城市人口3个参数对预测结果的影响,并提出参数选择的建议,为实际的环评工作提供借鉴。

As recommended in the“Technical guidelines for environmental impact assessment—Atmospheric environment”(HJ 2.2-208),the estimation model AERSCREEN has been widely used.Based on the case of a painting workshop area source,this paper selected initial vertical dimension of the area source,land use type and urban population as variable parameters to analyze the influence in the prediction work on large-scale area source by orthogonal experiments,and give suggestion on how to choose the parameters properly,providing a reference for actual EIA work.
