北京市实行机动车排放欧洲标准的环境效果分析

以2005年为基准年,在全面调查北京市城区道路交通、机动车保有运营状况的基础上建立机动车污染源排放清单,并借助ADMS-城市模型建立机动车污染物扩散模型,对北京市城区内的机动车污染物浓度进行了模拟;对国Ⅰ、国Ⅱ标准实施的污染物排放量变化及其对大气环境质量的影响进行回顾性评估,并预测实施国Ⅲ、国Ⅳ标准后,在未来能取得的污...

An environmental effect analysis for the application of european emission standards of motor vehicle in Beijing

The study makes a pollutant emission inventory for motor vehicles through an overall investigation of the traffic conditions based on the situation of year 2005 of the urban area of Beijing.Using ADMS system,an air pollutants concentration distribution model is constructed,and quantitative simulation analysis on the pollution emission from motor vehicles in Beijing is conducted.Then a retrospective environmental effect assessment is made on the application of applying motor vehicle emission standard,i.e.Ⅰ,Ⅱ,Ⅲand IV.It is concluded that the implementation ofⅠand Ⅱ standards has turned out to be quite big a success.On the baseline of 2005,if Ⅲ and IV standards are implemented,the effect of reducing CO pollution will be obvious in 2015,but for NOX it will just bring the air quality to a level of 2005,and to further improve the air environmental quality,more stringent measures or support policies must be imposed.
