中国大陆生物质燃烧排放的污染物清单

Inventory of atmospheric pollutants discharged from biomass burning in China continent

根据2000年各省市生物质的消耗资料,结合排放因子,计算了中国大陆生物质燃烧所排放的SO2、NOx、NH3、CH4、EC、OC、VOC、CO、CO2的总量及各省市的排放清单,并进一步细化到县、区级行政区.研究表明,生物质燃烧排放的污染物在地区间的分布极不均衡,排放量较大的包括华东、中南地区的各省市;各种生物质燃烧对各污染物的排放量的贡献差异很大,其中秸秆和薪柴是最主要来源;单位面积生物质燃烧排放污染物的量较高的地区由东北至中南围绕中国的主要农业产地呈带状分布.

Based on biomass consumption data in 2000 combined with discharge factors, the total amounts of SO2, NOx, NH3, CH4, EC, OC, VOC, CO, CO2 discharged from biomass burning in China continent and the discharge inventories of each provinces-city were calculated and elaborated to county and district. Very uneven distribution of pollutants discharged from each region, with larger amounts from the province-city in East-China and Middle-South-China. The contribution to the amount of pollutant discharged from each kinds of biomass burning was different greatly, in which straw and firewood were the main sources. The regions with higher discharged amounts of the pollutants per unit area distributed in a belt shape across the main places of agricultural production of China, from north-east to middle-south.
