摘　　要：通过对南昌郊区一片樟树林上空氨浓度的实地监测,用微气象学浓度梯度法计算了氨的干沉降速率,在稳定和中性大气情况下,氨的干沉降速率范围为一0.96—2.09cm.s^(-1),平均值为 0.62 cm.s^(-1).The ammonia concentrations over a small camphor forest at the northwest of Nan-chang city in Jiangxi province of China were measured. Dry deposition velocity of ammonia was calculated with micro meteorological concentration gradients method. The results show that under stable and neutral atmospheric situation the dry deposition velocity of ammonia lie in the range of -0. 96 - 2- 09cm · s-1 with a mean of 0. 62cm · s-1.
