| 摘 要： | 被动扩散技术以其低成本、操作简单、空间覆盖率较高等优点已在西方国家广泛应用于环境空气质量监测与调查，辽宁省环保局通过欧盟项目引进，本技术在葫芦岛市环境空气质量监测应用有4年时间。依据4年环境空气被动扩散管监测基础数据，分析了解葫芦岛市城区大气中NO2时空分布特征：高浓度值出现在交通区，季节上呈现春季明显低于其它季节。

| Abstract: | The passive diffuse cell with the merits of low cost, simple operation and higher space cover percentage is extensively adopted for monitoring and survey of ambient air quality. Through the introduction of European Commission project, the Environmental Protection Bureau of Liao Ning province has developed this technology to monitor the ambient air quality of Hu Lu Dao city for four years. According to the basic monitoring data of ambient air passive diffuse cell over four years, the spatiotemporal distribution characteristics of NO2 in urban atmosphere of Hu Lu Dao city are analyzed. It shows that peak concentration value appears in traffic district and the value in spring is obviously lower than values of other seasons. |
