摘　　要：根据政府间国际经济合作组织（OECD）和政府间气候变化专业委员会（IPCC）提供的计算方法，结合中国反刍动物的能量供应特点，对自1980年以来的广西反刍动物的甲烷排放量进行了估算．结果表明：反刍动物摄入总能的6．99％～7．17％通过甲烷排放损失掉，广西反刍动物的甲烷排放总量已经从1980年排放210．00g上升至2004年的534．10g．每年上升3．97％，速度较快，占全国反刍动物甲烷排放总量的5．90％左右。对估算结果作了分析，并结合广西反刍动物生产的发展趋势提出了建议。This paper presented a detail estimation of methane emission from ruminant animals in Guangxi of China according to the calculation method by Organization for Economic Co-operation and Development （OECD） and Intergovernmental Panel on Climate Change （IPCC）. The results showed that about 6.99 to 7.17 percent of gross energy taken by ruminant animals was lost through methane emission. The total methane emission from ruminants in Guangxi increased from 210. Gg in 1980 to 534.1 Gg in 2004, which increase 3.97% per year was about 5.90 percent of the total methane emission from ruminants in China. There are some uncertainties in estimations due to lack of experimental data, great efforts are needed to improve the accuracy of estimations. This paper analyzed the reliability of the results of estimation, and some relative adviees were suggested.
