鼎湖山臭氧、氮氧化物和太阳可见光辐射相互关系的研究

给出了１９９６年了在广东肇庆鼎湖山自然保护区对太阳可见光 段辐射，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。

The study on the relation of surface ozone,NOx and solar visible radiation in Dinghushan station

The observational results of surface ozone,NO and NO\-2 concentrations and solar visible radiation 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 and NO\-2 concentrations. In clear sky condition,the concentrations of surface ozone,NO and NO\-2 show a clear diurnal variation, and in cloudy sky condition, the diurnal variation is complicated. Both in clear sky and in cloudy sky conditions, there is a good correlation between solar visible radiation factor and the concentration of the surface ozone, NO,NO\-2 and the water vapor content in whole atmospheric column ( q\-1,q\-2,q\-3,q\-4 ); the formula is: ln Q vis / m=a\-1q\-1 a\-2q\-2 a\-3q\-3 a\-4q\-4 a\-0 . It is proved that the photochemical reaction in the atmosphere is the main cause to control the concentrations of surface ozone, NO and NO\-2 in clear and cloudy days.
