中文摘要	利用东部沿海城市天津大气边界层观测站(以下简称天津站)和西部兰州大学半干旱气候与环境观测站(SACOL)一年的臭氧和NO_X体积浓度观测资料,对比分析了两观测站点近地层臭氧浓度的逐月变化、频率分布、日变化特征以及与NO_X之间的相关关系。结果表明,两观测站点臭氧浓度月均值变化呈现出很好的一致性,均在47月出现高值,12月至次年2月出现低值,SACOL臭氧浓度月均值的最大值和最小值出现时间要比天津站推迟一个月。天津站臭氧体积浓度主要分布在10~50muL/m~3,SACOL则集中在10~70muL/m~3,春、夏季两观测站点臭氧体积浓度低于10muL/m~3的频率均很小,秋、冬季两观测站点臭氧浓度频率分布特征类似。两观测站点臭氧浓度日变化在4个季节均呈现典型的单峰型分布,SACOL臭氧浓度日最大值出现时刻要比天津站晚2h。两观测站点臭氧浓度与NO_X、NO_2、NO的浓度之间均呈显著的负相关关系。天津站与臭氧浓度的相关性最强的为NO,而SACOL则是NO_X。
英文摘要	The ozone and nitrogen oxides concentrations in Tianjin and Lanzhou were observed by Tianjin at-mospheric boundary-layer observatory and semi-arid climate observatory and laboratory(SACOL),these observation-al data were used to analyze and compare the monthly variations,frequency distributions and diurnal changes of ozoneconcentration in eastern coastal area and western arid area of China.The correlations between ozone and nitrogen ox-ides were also analyzed.The results showed that the variation of the monthly averaged ozone concentration of two sta-tions presented similar tendency.They were both higher in April to July,and lower in December to February of nextyear.The maximum and minimum monthly average ozone concentration of SACOL appeared one month later thanTianjin.The ozone concentration in Tianjin mostly distributed in 10-50muL/m~3,in SACOL was mostly ranged 10-70muL/m~3.The frequencies of ozone concentration bellow 10muL/m~3 were small in spring and summer for the two sta-tions.The frequencies were similarly between two stations in autumn and winter.The ozone concentrations of twostations both presented a typical single-peak distribution in four seasons.The daily maximum of ozone concentrationin SACOL appeared two hours later than that in Tianjin.There was a significant negative correlation between ozoneand NO_X,NO_2,NO concentration in both stations.O_3 had the maximal relationship with NO in Tianjin station,whilein SACOL O_3 was most correlated with NO_X.
