| 摘 要： | 文章基于Models3/CMAQ空气质量模式,利用北京及周边省市详细调查的污染源数据,采取双层网格嵌套技术建立起适用于我国华北区域的大气PM10数值模拟系统。在此基础上,文章设计了5种污染源情景方案,并对各种情景分别进行数值模拟,定量计算周边各省市对北京大气PM10的具体影响情况,得到2002年采暖季(1月份)和非采暖季(7月份)周边省市对北京大气PM10逐时浓度贡献情况。结果表明,外来污染物输送对北京大气PM10浓度影响较大,在采暖季和非采暖季外来影响分别为23.4%和40.0%。在周边各省市中,河北、天津、山西等地污染源排放对北京市大气PM10均具有不同程度的影响。

| Abstract: | Models3/CMAQ modeling system was used to study transboundary PM10 contribution to Beijing metropolitan region. Emission inventory for the 2-level nested model was built up through tailed investigation and collected data from Beijing and surrounding provincial environmental protection bureaus. Months of January and July in 2002 were selected as target periods for model predication. Five emission scenarios were designed and run by modeling system in order to quantitatively assess transboundary PM10 contributi... |
