【摘要】：本研究选取上海和杭州两市开展了非道路移动机械的实地调查,分析了各城市非道路移动机械的种类构成、使用特点、燃料类型、功率分布和排放标准等级,在此基础上建立了城市尺度非道路移动机械排放清单技术方法,编制了上海和杭州市2014年非道路移动机械大气污染物排放清单.结果表明,上海和杭州市非道路移动机械柴油消费分别为6.1×10~5t和3.2×10~5t,NO_x排放分别为3.09×10~4t和1.72×10~4t,PM_(2.5)排放分别为1.41×10~3t和8.1×10~2t,其中,挖掘机等建筑市政施工机械的排放贡献最为突出.非道路移动机械NO_x排放分别占两城市所有源的11.1%和16.1%,占流动源的18.5%和32.2%,已成为城市大气污染的重要来源之一.
[Abstract]:In this study, two cities, Shanghai and Hangzhou, were selected to carry out field investigation of off-road moving machinery, and the types, characteristics, fuel type, power distribution and emission standard grade of non-road moving machinery in each city were analyzed. Based on this, the emission inventory technique of non-road moving machinery in urban scale is established, and the emission inventory of atmospheric pollutants of off-road moving machinery in Shanghai and Hangzhou in 2014 is worked out. The results show that diesel consumption of non-road mobile machinery in Shanghai and Hangzhou is 6.1 脳 10 ~ (5) t and 3.2 脳 10 ~ (5) t respectively. The emission of Nox is 3.09 脳 10 ~ (-4) t and 1.72 脳 10 ~ (4) t / min respectively. The emission is 1.41 脳 10 ~ (3) t and 8.1 脳 10 ~ (2) t respectively. The NO_x emissions of off-road moving machinery accounted for 11.1% and 16.1of all sources in the two cities, and 18.5% and 32.2% of the mobile sources, respectively, which have become one of the important sources of urban air pollution.
