| 摘 要： | 根据OECD(1991)和IPCC提供的反刍动物甲烷排放量的计算方法，结合中国反刍动物的能量供应特点，初步估算2000年广东省反刍动物的甲烷排放量为215．10Gg，占全国反刍动物甲烷排放总量的4．3％左右，反刍动物摄入总能的6．99／5～7．5％通过甲烷排放损失掉。文中对估算结果做了分析，并结合广东省反刍动物生产的发展趋势提出了建议。

| Abstract: | This paper presents a detailed estimation of methane emission from ruminant animals in Guangdong province according to the calculation method by OECD (1991) and IPCC, analyzes the reliability of the results of estimation, and some relative advices are suggested. The results show that about 6.9 to 7.5 percent of gross energy taken by ruminant animals is lost through methane emission. The total methane emission from ruminants in Guangdong province is 215.10 Gg in 2000, about 4.3 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. |
