| 摘 要： | 北京周边地区污染源对北京市区大气环境的影响不可忽视.利用区域大气污染模式,系统模拟分析2002-08-17T09:00-2002-08-29T08:00污染传输过程;选择典型污染时段,结合气象资料进行比较分析,计算各时段周边地区和北京自身大气污染物对北京大气环境污染的贡献和贡献率;进一步证实了在大气条件有利于污染物输送的背景下,周边地区污染源的中远距离输送对北京大气环境质量的影响不可忽略.研究表明:有特殊天气背景时,即研究区域在西南风气流场的控制之下,周边地区污染源对北京的贡献比北京自身的大;没有特殊天气时,北京自身的贡献大于周边地区对其的贡献. |

| Abstract: | The influence of surrounding emission sources on Beijing's air quality is considerable to the improvement of its atmospheric environment.The regional air pollution modeling system was used to simulate the pollution transportation of regional scale from 09:00 am August 17,2002 to 08:00 am August 29,2002.Several typical pollution events were studied,and combined with the local meteorological data,the contributions of atmospheric pollutant in Beijing and its surrounding regions in each event were simulated.The result shows that in special atmospheric background,the air pollution impact on Beijing transported from mid-long distance of surrounding regions can not be neglected.The contribution of surrounding regions is more than that of Beijing in special weather conditions,i.e.when the research regions are controlled under southwestern air flow field, and the contribution of Beijing is more than that of surrounding region without the special weathers. |
| Keywords: | surrounding regions pollution transportation atmospheric environment contribution |
