摘要

With the gradual improvement of PM 2.5 pollution in China,the problem of ozone pollution is becoming more and more serious.In recent years,ozone has become the only one of the six major air pollutants increasing year on year in China,and the primary pollutant of air pollution in many cities of China in summer.In this paper,pollution characteristics of ozone and its relationship with meteorological conditions in China s provincial capitals and some economically developed cities(27 cities in total),and temporal-spatial distribution rules of ozone in China were analyzed,and influence and main source of ozone in China were summarized.The results were as below:daily change of ozone concentration showed as single-peak type,and the maximum generally appeared at 15:00-16:00,while the minimum generally occurred at 07:00-08:00.Seasonal change of ozone concentration mainly showed as single-peak type.In summer,ozone concentration was the highest,followed by spring and autumn,and its concentration in winter was the lowest.The influence of meteorological factors on ozone showed as that there was significantly positive correlation between ozone and temperature,radiation quantity,and significantly negative correlation between ozone and humidity,NOx.Ozone near surface will have adverse effects on biosphere,climate and ecological environment.The source of ozone can be divided into two kinds:man-made and natural,and the most important source of near-surface ozone is man-made.
