| 中文摘要: |
| 基于世博园区主要污染源的排污统计分析,运用ADMS-Urban模型对世博园区SO2浓度变化规律进行数值模拟计算,分析了风向、风速、云盖度及降雨等方面分析对SO2浓度扩散的影响程度,以及SO2污染世博规划区空气质量最严重的不利因素.结果表明,对世博规划区SO2浓度贡献最大的为杨树浦发电厂,云盖度对污染物浓度扩散有一定的抑制作用,降雨对污染物浓度有削减作用,降雨对污染物浓度的削减作用远远大于云盖度的抑制作用,SO2污染世博规划区空气质量最严重的不利因素为36.8°或190.8°的风向,这两种风向下世博规划区SO2浓度严重超标. |
| 英文摘要: |
| Based on the statistical analysis on discharge of main pollution sources, ADMS-Urban was put in use to simulate the variation of SO2 concentration in Expo area, including the effects of wind direction, wind velocity, clouds coverage and rainfall on the diffusion of SO2, as well as to find out negative factors influencing air quality in Expo planning area due to discharge of SO2. The results show that Yangshupu Power Plant gave most contribution on SO2 concentration to Expo planning area. Clouds coverage can... |
