东北地区非道路移动源排放清单研究及情景预测

与其他地区相比,东北地区冬季低温漫长,有其非道路移动源大气污染物排放清单的独自特征.本文将东北地区分成辽宁省城市群和哈长城市群进行分析.首先,基于《非道路移动源大气污染物排放清单编制技术指南》(试行)中的排放因子法建立非道路移动源排放清单,分析其排放以及时空分布特征.其次,结合相关政策目标基于情景分析预测2030年的排...

Study on a Non-road Mobile Source Emission Inventory and Scenario Prediction in Northeast China

Compared with other regions， Northeast China has its unique characteristics of non-road mobile source emission inventories due to its long and cold winter. In this paper， the analysis was divided into Liaoning Province and Harbin-Changchun Megalopolis. Firstly， the emission inventory of non-road mobile sources was established based on technical guide for preparation of air pollutant emission list of non-road mobile sources (trial)， and its emission and spatial-temporal distribution characteristics were analyzed. Secondly， the emissions in 2030 were forecasted based on the scenario analysis， taking into account of the relevant policy objectives. Finally， reasonable emission reduction recommendations were made. The results show that: 1) the emissions of PM₁₀， PM_2.5， NO_○x， THC， and CO were 13.0×10³， 12.5×10³， 205.6×10³， 37.0×10³ and 101.1×10³ t， respectively; 2) construction machinery accounts for the largest share of emissions in the two urban agglomerations with 44.5%and 44.8%， respectively; 3) the overall emission reduction can be improved by more than 50% under both the baseline scenario and the enhanced control scenario.
