鼎湖山地面臭氧、氮氧化物变化特征的分析

给出了１９９６年夏季在广东肇庆鼎湖山自然保护区对太阳紫外Ｂ辐射、地面臭氧、ＮＯ、ＮＯ２浓度的观测结果，对影响地面臭氧、ＮＯ、ＮＯ２的主要因子进行了分析，并得到了较好的结果．晴天条件下，地面臭氧浓度、ＮＯ、ＮＯ２浓度有明显的日变化；阴天条件下，地面臭氧浓度、ＮＯ、ＮＯ２浓度的日变化要复杂一些．晴天和阴天条件下，ＵＶＢ因子与ｑ１、ｑ２、ｑ３、ｑ４之间存在着很好的相关关系，其关系式为ｌｎ（ＱＵＶＢ／ｍ）＝ａ１ｑ１＋ａ２ｑ２＋ａ３ｑ３＋ａ４ｑ４＋ａ０．说明大气中的光化学反应是决定地面臭氧浓度、ＮＯ、ＮＯ２浓度变化规律的主要原因．

The analysis for the variation characteristics of surface ozone and NOx in Dinghushan Station

The observational results of surface ozone,NO,NO 2 concentrations and solar UVB during the summer of 1996 in Dinghushan biosphere reserve,Zhaoqing City,Guangdong province are given.A good result was got from the analysis of key factors affecting the surface ozone,NO,NO 2 concentrations.In clear sky condition,their diurnal variations was complicated.Both in clear sky and in cloudy sky conditions,there was a good correlation between solar UVB factor and factors of q 1,q 2,q 3 and q 4 which related to the concentration of surface ozone,NO,NO 2 and water vapor contents,the formula is:ln( Q UVB / m)=a 1q 1 a 2q 2 a 3q 3 a 4q 4 a 0. It was proved that photochemical reaction in atmosphere is the main cause to control the concentrations of surface O 3,NO,NO 2.
