Abstract In the present work, the total amounts of CH4, SO2, NOx, NH3, EC, OC, NMVOC, CO, CO2, TSP, PM10, PM2.5discharged from biomass burning in Chinese continent region were calculated with biomass consumption combined with emission factors. Spatial distribution of the pollutants and mass contribution of each type of biomass combustion were given. In general , in the year 2007 , the total emissions of CH4, SO2, NOx, NH3, EC, OC, NMVOC, CO, CO2, TSP, PM10, PM2.5was 3332.7, 335.3, 951.3, 7754.9, 783.7, 267.7, 6049.6, 76579.6, 743743.7, 7677.8, 6668.9, 4043.7kt, respectively. Sichuan, Anhui, Guangxi, Shandong, Henan and Jiangsu held high emission amounts while in Beijing, Tianjin, Hainan, Ningxia, Qinghai and Tibet, the pollutants amount was low. Straw and firewood burning were main emission sources, which share 93.8%~98.7% of the total emission. The main substances emitting pollutants differed in different regions as well as the emission intensity per unit area and per capita.
