【摘要】 根据2000年各省市生物质的消耗资料,结合查阅的排放因子,计算了中国大陆生物质燃烧所排放的TSP,PM10,PM2.5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,生物质燃烧捧放的颗粒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;各种生物质燃烧对颗粒物的排放量的贡献差异很大,其中秸秆和薪材是最主要来源;单位面积生物质燃烧排放颗粒物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.更多还原

【Abstract】 Based on biomass consumption data in 2000 and emission factors, the total amounts of TSP, PM10, PM2.5 emissions from biomass burning in China and emission inventories by provinces were calculated, then the inventories were assigned to county level. In general, significant unevenness emissions by regions was found, larger amounts of PM coming from the provinces in east-China and middle-south-China. The contribution to PM emissions from individual biomass type shows large difference, crop residue and biomass fuel are the main sources; The regions with higher emission amounts per unit area concentrated in a belt shape across the agricultural heartland of China from north-east-China to middle-south China.更多还原
