AERMOD和CALPUFF大气污染扩散模型的对比研究

摘要

大气污染控制模式能够分析雾霾的成因和发展趋势,预测大气污染物的迁移和转化规律,并对环境空气质量恶化起到一定的预防作用,系统阐述了AERMOD和CALPUFF大气扩散模型的理论及应用研究进展,并且比较了二者扩散模式的异同及各自适用范围.结果得出,近场范围内(小于50 km)使用AERMOD大气污染控制模型进行污染物的模拟预测,长距离(大于50 km)或复杂流场条件下使用CALPUFF大气污染控制模型,能够对大气污染的模拟预测起到良好预期效果.%Atmosphere pollution control model analyzes the origin and development of haze,and forecast the migration and conversion of air pollutant,and then to some extend prevent ambient air quality from getting worse.This article discussed the theories and applications of both AERMOD and CALPUFF atmosphere pollution control models,and analyze similarity and distinction between the two models.The results showed that AERMOD model should be used in near-field range(<50 km) to obtain the anticipated good results in atmosphere pollution simulation forecast while CALPUFF model should be used in far-field range(>50 km) or under complex flow field.
