摘要
调查了南京市机动车尾气对道路环境污染的状况 ,分析了城市道路建设对空气质量的影响。指出 ,从 1991年以来 ,南京市机动车总量和道路车流量持续快速增长 ,但由于城市道路条件的改善 ,道路通行能力有了较大的提高 ,道路两侧污染物NOx,CO浓度均有所下降 ,但仍分别高于对照点 2 2倍、3 2倍 ,道路汽车排气对城市环境空气质量的影响不容忽视。提出 ,随着道路车流量的不断增加 ,要改善城市环境空气质量 ,必须推广清洁燃料以及低污染车和零污染车 ,同时进一步加强道路建设 ,提高车辆通行能力 。
The pollution of motor vehicle exhaust to road′s atmospheric environment quality in Nanjing was investigated, the impact of urban road construction to atmospheric environment quality was analyzed. Since 1991, although the amount of motor vehicle and road traffic had been developing constantly and fast, the concentration of pollutants NO x and CO in road were decreased because of the improvement of road condition. But these concentration were 2 2 and 3 2 times more than the control sites, which indicated that the impact of motor vehicle exhaust to urban atmospheric environment quality can not be ignored yet. It suggested to use cleaner fuel, low pollution motor vehicle and zero pollution motor vehicle, and to strengthen road construction and to plant tree in the same time.
