- 摘要:提出在多条轨迹上应用轨迹模式,以实现对固定地区臭氧浓度日变化的模拟。应用该方法对北京燕山石化炼油厂地区的O3浓度日变化进行了模拟,结果表明模拟值和实测值十分吻和。进一步模拟了当地的臭氧生成特征,并讨论了当地的气象条件和源排放对O3生成浓度的影响,结果说明削减NOx的排放量是控制该地区光化学烟雾形成的关键,而降低烯烃和芳香烃在排放物中所占的比例也是控制该地区光化学烟雾的重要手段。
- Abstract:It is put forward to use trajectory model in multi-trajectory in order to simulate the diurnal change of the ozone concentration in specific places.The diurnal change of the ozone concentration in the area of Beijing Yanshan Petroleum and Chemical Industry Inc.was simulated by this method and it is shown that the simulation keeps consistent with the real measurement.Furthermore the local ozone formation character was simulated and the impacts of the local meteorological factors and emissions of pollutants on the formation concentration of ozone were simulated and discussed.The results show that the key of controlling the local photo-chemical smog is cutting down the emission of NOx,and reducing the percents of alkene and aromatic in the emission of NMHC is also very important.
