| 摘 要： | 利用线源长期平均浓度模式对面源的积分得到了一个用风向、风速和稳定度的联合频率计算大气面源长期平均浓度的新算法。通过对比分析表明，该算法比传统的按16个风向一次浓度的叠加算法简便、快速，且能消除叠加算法夸大16个常规风向附近计算点的浓度而缩小远离常规风向计算点的浓度现象。

| Abstract: | A new method of calculating long term mean concentration of air pollutant from area source is proposed by integrating the line source long term mean concentration model. Contrast research indicates that the new method is simpler and faster than the traditional method by adding concentration in 16 wind directions and can avoid traditional method of magnifying pollutant concentration in the area near these 16 usual wind directions and reducing pollutant concentration in the area far from these 16 usual wind directions. |
