摘　　要：调查统计了北京市机动车的汽车类型、环境情况、汽车里程、燃油类别等,运用COPERTⅣ模式计算了机动车NH_3排放因子,通过调查研究和模型模拟的方法得到了北京道路网的车型组成和车流量,利用Arc GIS软件构建NH_3排放清单,分析其空间排放情况。结果显示:国Ⅱ标准下汽油和LPG载客轻型车以及汽油载货车的NH_3排放因子较高,而柴油车NH_3的排放因子较低而且几乎不受各类排放标准影响。西部和北部地区道路较为稀疏,氨气排放量较低,高速路各个进京口和城区道路车流量大,氨气排放量较高。The emission factor of NH_3in motor vehicle exhaust gas was calculated by using the COPERT IV model and the emission of NH_3in Beijing area was calculated by investigating the basic data such as vehicle proportion,ambient temperature,vehicle running condition and oil quality in Beijing.The results showed that the NH_3emission factors for stateⅡstandard gasoline and LPG light passenger cars and petrol trucks were higher,while diesel vehicles were barely affected by emission standards and NH_3emission factors were lower.The survey statistic and model simulation method were used to obtain the vehicle composition and traffic volume data of Beijing road network,and emission inventory of vehicle exhaust NH_3was built with Arc GIS as the platform,and then spatial distribution characteristics were analyzed.The results showed that the emission intensity was higher in the vicinity of the urban ring roads and suburbs highways due to the large traffic volume,while in the northern and western mountain areas,the emission intensity was lower due to the lower density of the road network.
