The research of atmosphere actinochemistry mainly aimed at the photochemical reaction occurred by primary nitrogen oxides pollutant (NOX, NOx=NO+N02) and volatile organic compounds (VOCs) under the intense irradiation of sunshine. Ozone (O3) is the main component of this admixture called actinochemistry fog which consisted of reaction products and reactant. The increase of ozone concentration day by day observed recently must be related to the deve-lopment of economy, especially the uprush of motor vehicle holding amount which led to oz-one concentration increasing rapidly in city areas. High concentration of ozone not only harmful to mankind health and ecology environment, but also the important component of haze of city atmosphere which has been considered as the important reason of the visibility decreasing.The paper has studied the reaction process and characteristic of atmosphere actinochem-istry in Beijing area to find an effective way to decrease the ozone concentration by the measure of observation. It would improve the quality of atmosphere environment we depended on.Because a good many factors influenced the formation of actinochemistry fog, it was complicated of the relation between fog forming essential and result. In order to obtain the predictable correlationships in those complicate factors, the routine gas pollutant data obtained by the auther during Nov.2007 in China Research Academy of Environmental Sciences in Beijing were classified and analyzed by the auther The correlation and characteristic of data based on the hour and day change characteristic of pollutants has been analysed by Origin software. Then, city actinochemistry pollution analysis and discussion of Beijing area have been carried out based on pollutants concentration obtained by real monitor. It was indicated that the photochemical reaction of Beijing area has been affected by native pollutant as well as pollutant movement, and the active time of photochemical reaction has showed the trend of ahead of schedule. Also, this paper has provided important theory for actinochemistry fog forming mechanism.
