| 摘 要： | 以杭州市全市域为研究对象,基于机动车排放管理数据库和IVE模型本地化后计算出市区、城区、城郊和郊区4类区域及快速路、主干路和次干路3类道路的各类机动车排放清单,利用Arc GIS及杭州市路网信息建立了1 km×1 km网格化空间分布,分析了机动车污染物排放特征.结果显示,杭州市机动车各污染物NO_x、CO、PM_(2.5)和VOCs的年排放量分别为4.9×10~4、12.5×10~4、0.2×10~4、2.1×10~4t.各种车型中,中重型货车对NO_x和PM_(2.5)的贡献均最大,分别为45.8%和36.3%,其次为大中型客车、公交客运,小微型客车对CO和VOCs的排放贡献最大,分别为69.3%和51.1%.机动车各污染物排放强度均呈现由城市中心向城市边缘递减的趋势,高排放区域集中在城中心及城南和城北区域,同时各污染物排放量日变化特征明显,均出现弱双峰现象.

| Abstract: | This study calculate the localized area, urban,rural and suburban areas 4 types of expressway, trunk road and secondary trunk road 3 kinds of vehicle emission inventory in Hangzhou City by using motor vehicle emissions management database and IVE model, to established the distribution of 1 km×1 km grid space by using the information of road network and ArcGIS software, analyzed the emission characteristics of motor vehicle pollution. The results showed that the emissions of NOx, CO, PM2.5 and VOCs were 4.9×104, 12.5×104, 0.2×104, and 2.1×104 t, respectively. The duty trucks contributed mostly in NOx and PM2.5 formation, accounted 45.8% and 36.3%, respectively. The contribution of small cars to CO and VOCs emission were 69.3% and 51.1%, respectively. The motor vehicle pollutant emission intensity decreased from the city center to the edge of the city, high emission regions are concentrated in the city center and the south and north region. At the same time, the diurnal variation of the pollutant discharge is obvious. |
