摘　　要：建立了16个风向下的三维多箱模式,该模式充分考虑了污染源的空间变化、气象条件和周围环境对污染扩散的影响,以及干沉积和化学转化等物理化学机理对SO2的去除作用,根据质量守恒定律,得到了箱体方程,最后将该模式用于石家庄市区SO2质量浓度的预测,并对其进行了验证,结果表明多箱模型是预测市区和经济开发区的大气质量最佳方法之一。In this paper,three dimension multi-box model of 16 downward wind direction was introduced.The model take the spatial variations of the emission source and the meteorological conditions' effects on the pollutions' diffusion into account.The model can reflect physical and chemical removal mechanisms of SO_2 based on the rule of constant quality,the equation of SO_2 concentration in each box was acquired.This model was applied to predict SO_2 concentration in Shijiazhuang City,the results were tested and it was found that the multi-box model was one of the best methods to predict atmospheric environmental quantity in cities and economic development districts.
