The Present Status of the Emission Methane in China
中国甲烷排放现状

The emission of methane in China in 1990 and 1994 is estimated Firstly, the emission of methane in 1990 is collected and improved, especially the emission of methane from landfill is calculated Secondly, the emission of methane in 1994 is calculated according to the updated data Results show that the emission of methane in 1990 and 1994 are 30 92 Tg, and 32 91 Tg respectively The emission of methane from coal mining, oil and gas, animal manure and biomass domestic livestock increases while the emission of methane from biomass fuel and flooded rice fields decreases in 1994 compared with that in 1991 There is no great change of methane emission from the compost
