| 摘 要： | 近年来随着机动车保有量的快速增加,北京市机动车排放污染受到越来越多的关注。本研究应用COPERTⅣ模型计算了北京不同类型机动车排放因子,根据保有量和年均行驶里程等基础数据计算了2009年机动车尾气污染物排放量;调查了北京典型道路车流量和车辆运行速度等参数,计算机动车尾气排放强度,得出了典型道路不同污染物的综合排放因子;应用COPERTⅣ模型分析了车速对不同污染物排放的影响,将基于G IS的机动车活动强度、行驶速度和排放因子结合在一起,得到了北京机动车尾气排放网格分布清单。结果表明:CO排放量为71.58×104t,HC排放量为7.95×104t,NOx排放量为8.77×104t,PM排放量为0.38×104t。北京城区高峰小时CO排放量为143.9 t/h,HC排放量为18.6 t/h,NOx排放量为12.5/h,PM10排放量为1.14 t/h。

| Abstract: | Over the past few years,there has been a rapid increase in the amount of vehicles in Beijing.The tailpipe emissions from these vehicles are causing an increasing impact on air quality.In this paper,detailed surveys were conducted on vehicle population and the distribution of vehicle types,vehicle ages and mileages in 2009.This data formed the foundation of detailed analysis of the emission inventory,distribution of total vehicle emissions by fuel type and by vehicle type.The results showed that the total CO... |
