确定道路交通氨排放因子方法研究与应用

Research and application for ammonia emission factor of road transportation

近年来,来自城市道路交通的氨(NH3)排放污染越来越严重,加剧了PM2.5颗粒物的形成,严重危害到人体健康。因此,建立高时空分辨的城市道路交通的氨排放清单对于城市大气污染防治与清洁空气的管理十分重要。目前,来自于道路交通的氨排放主要使用排放因子法进行估算,因此获得符合城市道路交通特点的氨排放因子对建立高时空分辨的排放清单尤为重要。本文系统阐述了5种获取氨排放因子方法的国内外研究现状及最新进展,总结和评价了每种方法的适用性和优缺点,并对其在高时空分辨排放清单的应用进行了展望,期望为建立道路交通的高时空分辨氨排放清单提供方法参考。

Ammonia (NH 3 ) pollution from urban road transportation has been becoming more and more serious,which aggravates the formation of PM 2.5 particles and seriously harms human health.Therefore,it is a key issue to establish an ammonia emission inventory with high spatial and temporal resolution in order to control the urban air pollution and clean air management.Currently,the method of building the ammonia emission inventory from road transportation is mainly based on the emission factor method.Therefore,obtaining ammonia emission factor according to the transportation characteristics from urban roads is a key for establishing high-resolution emission inventories.This paper comprehensively introduced the research status and developments of five methods of obtaining ammonia emission factors;And it summarized and analyzed the advantages and disadvantages of each method;The application of the methods in the establishment of the high spatial and temporal resolution emission inventory was discussed in detail.We hopefully provide methodological references for establishing a high-time-space-resolved ammonia emission inventory.
