中国华北地区冬季大气污染物航空测量(I)—空中气态污染物污染特征研究

为掌握致酸大气污染物SO₂和NO_x的空间浓度分布，并探讨上述污染物扩散、迁移和传输规律，进而研究其在酸性降水形成过程中的作用，在“八五”期间酸性降水的研究中，针对中国华北地区城市和工业集中以及S0₂和NO_x等酸性大气污染物排放量大的特点，以石家庄及其以东地区为飞行区域，进行了华北地区冬季空中S0₂和NO_x污染特征的航空测量。通过测定发现在华北地区1.5km左右的空中存在着S0₂和NO_x高浓度污染空域，同时S0₂存在着高浓度汇集区。 

Aircraft Measurement of Atmospheric Pollutants in Winter in North China I : Research on Pollution Properties of Gaseous Pollutants

In order to understand spatial distributions of acidity causing atmospheric pollutants such as SO 2,NO x and study the diffusion and transmission properties of the above pollutants and thus therir contributions to the formation of acidic precipitation,in he research of acidic precipitation during the Eighth Five Year Plan Period,the aircraft monitoring area in and to the east of Shijiazhuang was selected and aircraft monitoring performed on pollution properties of SO 2 and NO x in winter in North China with consideration of the high density of cities and industries in this area.It was found from the monitoring that there are heavily polluted spatial areas caused by SO 2 and NO x at the height of about 1.5 km and,at the same time,there are areas concentrated with high SO 2 in North China.
