摘　　要：2005-05-22─2005-12-31,在中国科学院大气本底观测网兴隆站对微量气体成分进行连续测量,获得了O3,NOx(NO,NO2),CO2和SO2等气体组分的变化特征和变化规律,并得到了它们的浓度水平.初步分析表明,φ(O3)在6,9月出现高值,12月出现最低值;φ(NOx)的最低值出现在8月,8─11月缓慢增长,NO在NOx中所占比例非常小;φ(SO2)的最低值出现在7月,之后逐渐增加;φ(CO2)的最低值出现在8月.观测资料表明,兴隆站空气质量最好的时间为7─8月.并对它们之间的相互作用及与辐射的关系进行了研究.During May 22 to December 31 of 2005, continuous measurements of some trace gases at Xinglong Station, atmospheric background observation network of Chinese Academy of Sciences were carried out. Some variation characteristics and variation regularity of O3, NOx （ NO, NO2 ）, CO2, SO2, and their present concentrations were obtained. In general, O3 displayed a higher concentration in June and September, and the lowest concentration in December. NOx indicated the lowest concentration in August, and slowly increased during August to November, the ratio of NO to NOx is very low. SO2 showed the lowest concentration in July, and then gradually increased. CO2 exhibited the lowest concentration in August. Based on the present observation, good air quality at Xinglong Station is in July and August. and to study their interactions and the relations between them and solar radiation.
