动物废弃物源甲烷排放量的初步估算与减缓技术选择

Methane emitted from livestock manure and mitigation technologies.

根据ＩＰＣＣ的国家温室气体排放清单编制指南，初步计算了中国动物废弃物源的甲烷排放量。２０年间，中国动物废弃物源的甲烷排放量增加了７５％，１９９０年的甲烷排放量为１．１９８Ｔｇ，占全球的１０％左右。并提出发展沼气池、贮留池不仅能减少甲烷排放，而且能产生其它的环境效益和经济效益。

Based on the greenhouse gas Inventory reference manual,this paper calculated the methane emitted from Chima’s livestock manure.The emission was 1.198 Tg in 1990 and in-creased 75 % from 1970 to 1990 Covered lagoons and biogas generators were proposed to mitigate the methane emissions of livestock manure. Using of these two technologies can not only reduce methane emission, but also get environmental and economoc benefits.
