| 摘 要： | 较详细地介绍了美国环保总局的第三代空气质量模式系统Models-3的特点，并且针对兰州市冬季采暖期污染严重的特点，选取2002年12月份的个例，将兰州市最新的大气污染源资料加入模式中．对模式进行调试并检验了该模式对兰州污染的模拟性能。从模式对SO2，NO2和O3等几种大气污染物浓度的模拟结果与监测资料对比分析，表明该模式系统较好地模拟出了SO2，NO2的空间分布格局，模拟结果与监测结果比较吻合，而且模式模拟的污染物浓度场比较均匀；模式模拟的O3的日变化规律与资料分析结论基本一致，也符合O3的生成机理。因此该模式系统对于复杂地形条件下的城市污染物输送具有一定的模拟能力。

| Abstract: | The characteristic of Third-Generation Air Quality Modeling System and its application to Lanzhou have been introduced in somewhat detail. Because air pollution is serious during winter heating period, a case in December 2002 is chosen and a 48 h integrating simulation experiment was carried out utilizing the latest pollution sources data. Comparing the simulation results of SOz, NO2 and O3 with the observation ones, it is shown that the model system can better simulate the spatial distribution trend of SO2 and NO2. Also the simulation and monitoring results are more identical and the simulation concentration field is more even. The simulation result of ozone is unanimous basically with data analysis and according with the formulation mechanism of the ozone too. So this air quality model system has ability to simulate air pollution transport in complicated topographical city of Lanzhou. |
