| 摘 要： | 采用被动扩散采样技术，在遂宁市辖区16km×16km网格区域内开展了为期1a的环境空气NO2监测，分析了不同时空内的NO2浓度变化趋势。研究表明：NO2浓度季节变化规律是：冬季〉春季〉秋季〉夏季；在全市各个区域中，浓度最高值出现在全市工业集中及车流量较大的区域（船山区）；受遂宁市污染源整体布局以及主导风向（西北风）的影响，全辖区范围内NO2呈现西北低、东南高的趋势。

| Abstract: | The atmospheric NO2 concentration has been monitored for one year by using the passive sampling method within the grid area of 16km × 16km in Suining. We analyzed the change of NO2 concentration in different time and area. The results showed that the seasonal change trend of NO2 concentration was ： winter 〉 spring 〉 autumn 〉 summer. In the whole city, the highest concentration occurred in the industrial area and the area with large vehicle flow （Chuanshan District）. Influenced by the layout of the pollution sources and the dominant wind direction （northwest）, the NO2 concentration in the northwest is lower than the southeast. |
