| 中文摘要: |
| 对黄河中上游能源化工区近地面和边界层顶气象流场及该区域大气污染长距离输送产生的跨界环境影响趋势特征进行了分析。结果表明，该区域近地面和边界层顶的流场总体上为西北向东南流动，大气污染物长距离输送可能影响的区域主要为华中地区；区域冷空气的活动对其大气污染物的清除起重要作用；通过CALPUFF模型的模拟结果表明，该区域SO2的影响程度和范围明显大于NO2，在区域内部存在污染物浓度较高的区域，但未对区外造成显著跨界环境影响。 |
| 英文摘要: |
| The crossing boundary impact of air pollutant was analyzed by meteorological flow of boundary layer and air quality model simulation. The results showed that the meteorological flow direction of boundary layer and near-land surface was mainly from north-west to south-east, and the main influenced area by long-distance-transported air pollutant was in central china. The simulation results of air model CALPUFF showed that the influence area of SO2 was larger than NO2, and there was two high concentrated sites inside the region but the air pollutant did not cause remarkable crossing boundary impact. |
