摘　　要：采用二维多箱模型对石家庄市区的大气污染物ＳＯ２进行了计算，分别计算４个风向的各子箱污染物浓度，然后按其风向频率加权取和得到平均浓度．把计算结果与地面监测值和１９９４－０１中国环境科学研究院的高空航测值进行了比较分析后发现，多箱模型预测大气环境比单箱模型和其它预测方法产生的误差要小．从而证明用多箱模型预测市区和经济开发区的大气环境是最佳方法之一．In this paper,atmospheric SO 2 concenration in Shijiazhuang City has been calculated by using two dimension multi box model.The concentrations of every box in four wind directions has been also calculated,and then average concentration in every box has been obtained by weighting method on wind direction frequencies.Comparing calculating values with monitoring concentrations on the ground and high altitude plane monitoring values by Chinese Recearch Academy of Environ.Sci.in January 1994,it was found that the predicting result by multi box model brings smaller error than that by single box model.Author recognizes that the method of prodicting atmospheric environmental concentration in cities and economic development districts by multi box model is one of the best methods.
