备注

为进一步改善空气质量,提升宜居水平,非道路移动机械排放控制已成为环境治理的重要领域.本研究通过对中国深圳市非道路移动机械的实地调查和数据调研,分析深圳市非道路移动机械各特征参数,建立深圳市非道路移动机械排放清单.结果表明,2017年深圳市非道路移动机械NOx、细颗粒物(PM2.5)、可吸入颗粒物(PM10)、HC、CO、黑碳、有机碳及挥发性有机化合物等8类污染物的排放量分别为6 162.0、419.7、442.3、983.9、4 170.7、209.7、64.4及920.2 t.在所有非道路移动机械类型中,挖掘机排放占比最高,达到28.06%; NOx排放量占比最高,占总排放的46.04%.定量分析NOx排放清单的不确定性,在95%置信区间的平均值范围为(4 940.1,7 661.2)t,不确定性范围为[-21.1%,22.6%].研究结果可为非道路移动机械排放控制及制定减排措施提供参考和依据,对未来排放清单的建立提供指导.
In order to effectively improve the air quality and the livable level, emission control of non-road mobile machinery(NRMM)has become an important area of environmental governance. Based on the site investigation and data collection of NRMM in Shenzhen, we analyze the feature parameters of NRMM and establish the emission inventory. The results show that the emissions of NOx, PM2.5, PM10, HC, CO, black carbon(BC), organic carbon(OC)and volatile organic compounds(VOC)are 6 162.0, 419.7, 442.3, 983.9, 4 170.7, 209.7, 64.4 and 920.2 t, respectively. In all types of NRMM, excavator emissions account for the highest proportion, reaching 28.06%. Among the eight pollutants, NOx emissions account for the highest proportion, reaching 46.04% of the total emissions. Quantitative analysis of the uncertainty of NOx emission inventory shows that the average value range of 95% confidence interval is(4 940.1, 7 661.2)t, and the uncertainty ranges from -21.1% to 22.6%. The research results can provide reference and suggestions for the control policy of air pollution and the establishment of emission inventory of NRMM.
