摘　　要：颗粒物污染是影响中国城市空气质量的首要因素,交通扬尘是城市大气颗粒物污染的主要来源之一,排放清单及排放特征研究是进行环境影响分析、控制措施成本效益分析、控制方案制定以及进行环境管理的基础。本文对呼和浩特城区典型道路路面尘负荷进行采样分析,现场调研不同类型道路车流量和车辆构成,应用AP-42排放因子计算典型道路交通扬尘排放因子,建立了基于G IS的排放清单数据库。结果显示:胡同的PM10排放因子最大,其次分别为环城路、支路、次干道和主干道;环城路的PM10排放强度最大,其次为主干道、次干道、支路和胡同;基准年2006年呼和浩特城区交通扬尘PM10排放量为22 715 t;从空间分布看,环城路以内网格排放源强较高,中心城区排放强度最大。PM10（particle matter less than 10μm） with fugitive road dust is one of the main sources has become the primary pollutant which influence Chinese urban air quality in recent years.Emission inventory is the basis of air quality modeling,cost-benefit control,regulation planning and environmental management.In this study,silt loading was sampled for 30 roads and traffic volume was investigated.AP-42 emission factor was used to calculate the emission of road fugitive dust PM10 in Huhhot urban area.GIS based inventory was completed.Road fugitive dust PM10 emission was 22 715t in 2006.The emission factor for different types of roads were localring roadcollectorsminor arterialmajor arterial,and the emission strength for different types of roads were ring roadmajor arterialminor arterialcollectorslocal.The emission strength within in ring road was high and the highest emission strength is in the down town area.
