| 摘 要： | 近地面臭氧是空气中氮氧化物和挥发性有机物发生光化学反应的产物，其浓度与气象条件密切相关。晴天少云、紫外辐射较强、温度较高、相对湿度较低以及风速较小的天气，均有利于臭氧的生成，其中紫外辐射是产生臭氧最关键的因素。臭氧前体物（氮氧化物和挥发性有机物）的浓度及其比值是影响近地面臭氧浓度的另外三个重要因素。我国大多数城市的O3处于VOC控制区，即NOx浓度的增加会引起O3浓度的降低，而VOCs浓度的增加则会使其浓度升高。因而VOC源解析问题成为近年来O3研究的一个热点问题。同时，由于气溶胶可以直接吸收、散射太阳紫外辐射、短波辐射以及大气长波辐射，因此气溶胶的存在会影响大气中光化学反应的进程，从而影响臭氧的光化学生成，气溶胶对近地面臭氧的影响已成为目前大气环境的前沿课题。

| Abstract: | Surface ozone is the product of photochemical reactions of nitrogen oxides and volatile organic compounds in the air, whose concentration is closely related to the weather conditions. Under the weather conditions, such as sunny, strong ultraviolet radiation, high temperature, low relative humidity and small wind speed, surface ozone is easier produced. UV radiation is one of the most critical factors to produce ozone. Concentrations of nitrogen oxides (NOx) and volatile organic compounds (VOCs), and the ratio of them are the other three essential factors to the concentration of ozone. Concentrations of ozone in many cities, which increase with the decrease of NOx and the increase of VOCs, are controlled by the concentrations of VOCs. Thus the study on VOCs source becomes a hot issue of ozone in recent years. Meanwhile, since aerosols could directly absorb and scatter ultraviolet radiation, the solar radiation and atmospheric long-wave radiation, aerosols would affect the process of photochemical reactions in the atmosphere and then the concentrations of ozone. Thus, the study on impacts of aerosols on surface ozone has become the topics at the forefront of the atmospheric environment. |
