摘要
大气污染物浓度权重轨迹模型是一种研究大气污染物的区域输送问题的常用模型,但这一模型只考虑大气污染物浓度对目标城市的影响,而不考虑大气污染物持续输送时间的影响。针对此缺陷,提出了一种新的大气污染物源区计算模型——排放量权重轨迹模型,将污染物持续输送的时间因素引入模型计算中,计算出网格的权重排放量,并将权重排放量作为对目标城市污染贡献度的新衡量标准。
When studying the regional transport of air pollutants,the Concentration Weighted Trajectory(CWT)model is often used.But CWT only considers the influence of atmospheric pollutant concentration on the target city,without considering the influence of transportation period.In the article,a new source model---Emissions Weighted Trajectory(EWT)model was proposed,in which the factor of transportation period was introduced and the weighted emission was considered as the new criterion to measure the pollution level.
