农作物残留物的燃烧是区域和全球范围内痕量气体（CO、CO2、NO、NO2和NOx）和颗粒物的主要来源。利用自制的燃烧炉和气溶胶室，研究了水稻、小麦和玉米秸秆燃烧过程中的气体和颗粒物排放。结果表明，稻草的CO_2、CO、NO、NO_2和NOx的排放因子分别为791.3、64.2、1.02、0.79和1.81 g kg（-1），小麦秸秆为1557.9、141.2、0.79、0.32和1.12 g kg（-1），稻草为1261.5、114.7、0.85、114.7、0.32和1.12 g kg（-1）。玉米秸秆分别为0.43和1.28 g kg（-1）。相应的颗粒数排放因子分别为1.8 × 10（13）、1.0 × 10（13）和1.7 × 10（13）颗粒kg（-1）。2004年中国水稻、小麦和玉米秸秆焚烧产生的CO、CO2和NOx排放总量分别为22.59、252.92和0.28 Tg。水稻秸秆、小麦秸秆和玉米秸秆的CO、CO2和NOx排放量分别占总排放量的13.9%、15.3%和31.4%、32.9%、32.5%和20.9%、53.2%、52.2%和47.6%。此外，还利用简单的地理信息系统（GIS）绘制了中国不同区域的农作物秸秆焚烧排放分配图。(c)2008爱思唯尔有限公司版权所有。
The burning of agricultural crop residue represents a major source of trace gases (CO, CO2, NO, NO2, and NOx) and particulate matter on a regional and global scale. This study investigates the gaseous and particulate emissions from the burning of rice, wheat and corn straws, which are three major agricultural crop residues in China, using a self-built burning stove and an aerosol chamber. Emission factors Of CO2, CO, NO, NO2 and NOx were measured to be 791.3, 64.2,1.02, 0.79 and 1.81 g kg(-1) for rice straw, 1557.9,141.2, 0.79, 0.32 and 1.12 g kg(-1) for wheat straw, and 1261.5, 114.7, 0.85, 0.43 and 1.28 g kg(-1) for corn straw, respectively. The corresponding emission factors of particle number are 1.8 X 10(13), 1.0 x 10(13), and 1.7 x 10(13) particles kg(-1), respectively. The total emissions of CO, CO2, and NOx from rice, wheat and corn straw burnings in China for the year 2004 were estimated to be 22.59, 252.92, and 0.28 Tg, respectively. The percentages of CO, CO2, and NOx to the total emissions were 13.9%, 15.3%, and 31.4% for rice straw, 32.9%, 32.5%, and 20.9% for wheat straw, and 53.2%, 52.2%, and 47.6% for corn straw, respectively. In addition, the emission allocations of agricultural crop residue burning were also plotted in different regions of China using a simple geographic information system (GIS). (c) 2008 Elsevier Ltd.
