摘　　要：主要对大气环境防护距离设置选用的预测模型及预测条件进行了对比分析;推荐采用Aermod模式进行预测,即,计算项目所有排放源产生的污染物,并考虑地形影响,预测近三年气象条件下污染物小时浓度最大贡献值超标区域,设为大气环境防护区域。此方法更为准确地表达了大气环境防护距离的设置意义,也更符合实际情况。This paper mainly makes a comparative analysis of prediction models and prediction conditions which are used in atmospheric environmental protection distance setting and recommends Aremod model for prediction.This model requires calculating the whole pollution generated by the entire emission source,considering topographic influence,and being based on meteorological condition in recent three years to predict the area whose largest contribution value of pollutant concentration per hour exceeds the standard as atmospheric environmental protection area.This method fully reflects the magnificence of atmospheric environmental protection distance setting and also better confirms to reality.
