| 摘 要： | 利用WRF模式与多尺度空气质量模式(CMAQ)系统模拟了试验期间(2005年1月30-2月2日)兰州市城区SO2的地面浓度,并根据模拟结果进一步分析了兰州市冬季污染物的空间分布特征。研究结果表明西固区和城关区各有一处污染物高浓度区域；受排放源空间分布和气象场的综合影响,夜间SO2地面污染范围小于日间,夜间污染物地面最大浓度明显高于日间,夜间模拟区域平均值低于日间；水平流场和山谷风环流形成的垂直运动均对污染物地面浓度有明显影响。

| Abstract: | SO2 ground concentration in Lanzhou from30,Jan to 2,Feb was simulated by WRF model and multiscale air quality model, and spatial distribution of pollutants in Lanzhou city was further analyzed. The research results show that SO2 pollution range less than the daytime, and SO2 ground concentration at night was significantly higher than that in daytime by the comprehensive influence of the spatial distribution of the emission and meteorological field characteristic; Horizontal flow field and vertical flow field formed by valley wind circulation have obvious influence on ground level pollutant concentration. |
