东北地区非道路移动源排放清单研究及情景预测.

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， PM2.5, 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.
