| 摘 要： | 采用Lagrangian传输、扩散、沉降模式计算了1994年9、10月份(非采暖期)、1995年1月和2000年1月(采暖期)北京地区SO2的变化规律,并分别计算了北京市不同类型的排放源以及周边地区污染源对平均地面SO2浓度的贡献.计算结果与实际观测资料对比表明,模式能够较好地模拟北京地区SO2的浓度量级和逐日变化趋势.北京地区地面SO2浓度受天气条件的影响较大.采暖期,北京当地排放源的影响相对较大;但在大气条件有利输送的背景下,来自周边地区污染排放源的影响不容忽视. |

| Abstract: | Using the Lagrangian transport, dispersion, and deposition model to calculate the variation of surface SO 2 during the periods from September to October of 1994, January of 1995 and January of 2000 in Beijing. Further the source contributions of SO 2 from the regions surrounding Beijing are studied. Model results indicate that the simulated concentration levels and their daily variations are in good agreement with the observations in all periods. The concentrations of surface SO 2 varies in different weather conditions. The Beijing local emissions make greater contributions to the surface SO 2, but in some weather conditions the contributions from sources out of Beijing became an important part, i.e. in some situations, the influences from non local emissions are not negligible. |
