惠州市城区NO2污染水平的分析与模拟

分析了2004年惠州市城区各监测站点的NO2数据,结果表明,NO2对城区空气质量影响不大。采用了城市空气质量管理软件模拟了NO2空间分布及日变化情况,且与实测值的比较分析表明,模拟结果在城区内有可比性。但地处城市边缘地带的污染模拟受光化学和区域性污染的影响,有待于进一步研究。所得结论可为惠州市城区优化布点的研究提供一定的参考。

Analysis and Simulation of NO2 Pollution Levels in Huizhou City Zone

This paper presents the preliminary study of the project for "Optimization of the atmospheric environment monitoring stations in Huizhou city zone".Data of the year 2004 is analysed,which were collected from the monitoring stations in Huizhou city zone.The results show that NO_2 has minute impact on the air pollution in the city zone.Spatial and temporal simulation of NO_2 distribution is made by using Urban Air Quality Management software.Compared with the observations,it shows that the simulation in the city zone is reliable.Howerer, further research should be carried out in the boundary areas where the simulation is much more affected by photochemical pollution and the regional intersectional pollution.The result from this paper could provide valuable reference to the optimization research for the distribution of monitoring stations in Huizhou city zone.
