摘　　要：非道路移动源排放正逐渐成为影响我国空气质量的重要来源之一。本文在调研2017年我国非道路移动源分类保有量的基础上,测算了2017年我国工程机械、农业机械、船舶(渔船、客货船等)、铁路内燃机车、飞机(起降阶段)等主要非道路移动源碳氢化合物(HC)、氮氧化合物(NOx)和颗粒物(PM)的排放状况,并以工程机械为例分析了排放标准升级和采用颗粒物捕集器(DPF,Diesel Particulate Filter)进行治理改造对非道路移动源减排的影响。研究表明,2017年我国主要非道路移动源碳氢化合物排放77.9万吨,氮氧化合物排放573.5万吨,颗粒物排放48.5万吨。在2019年主要非道路移动源保有量持续增长的情况下,提前实行国IV阶段排放标准可减少工程机械各种污染物排放约0.8%~4.4%,国Ⅰ、国Ⅱ工程机械加装DPF后颗粒物减排可达20%左右,挖掘机、装载机与叉车减排效果明显。本研究可为我国非道路移动源排放管控提供思路。Non-road mobile source emission is gradually becoming one of the important sources of air pollution in China.Based on the investigation of the classified populations of non-road mobile sources in China, the emissions of hydrocarbons(HC),Nitrogen Oxides(NOx) and particulate matter(PM) from construction machinery, agricultural machinery, ships(fishing vessels, passenger and cargo vessels),railway diesel locomotive and aircraft(take-off and landing) in 2017 were estimated.Taking construction machinery as an example, the influence of upgrading emission standards and using Diesel Particulate Filter(DPF) to reduce emissions from non-road mobile sources were analyzed.The results show that in 2017,the main non-road mobile sources in China emitted 779,000 tons of HC,5735,000 tons of NOx and 485,000 tons of PM.In 2019,with the continuous increase population of major non-road mobile sources, the early implementation of the National Phase Ⅳ emission standard can reduce the emission of various pollutants from construction machinery by about 0.8 to 4.4 percent.PM Emission can be reduced by about 20% after the Phase Ⅰ and Phase Ⅱ construction machineries were installed with DPF.The effect of emission reduction for excavators, loaders and forklifts is obvious.The study can provide ideas for the non-road mobile source emission control in China.
