摘要
针对新一代大气污染估算模式AERSCREEN中,面源初始垂向扩散参数、城市人口参数、土地利用类型参数没有明确定义的情况,通过设置不同长宽的面污染源,选取最大小时浓度和最大小时浓度出现的点距污染源距离为考察指标,采用正交试验法,分析了这3个参数对预测结果的影响,并且给出了如何更为合理地选择参数的建议,以期为模型应用提供参考。
The new generation air estimation model AERSCREEN does not have clear definitions of initial vertical dimension of area source, urban population and land use type. Therefore, this paper set the area sources with different length and width, selected the maximum hourly concentration and the distance of maximum hourly concentration from the source as the investigation indexes, and analyzed the influence of these three parameters by orthogonal experiments. In addition, this paper put forward suggestions on how to choose the parameters more reasonably, providing a reference for the AERSCREEN model application.
