中文摘要：

反刍家畜瘤胃甲烷气体的排放是一种能量损失，同时对大气环境具有较强的增温效应。对放牧家畜甲烷气体排放的研究可以为确定天然草原温室气体的源与汇和制订减缓策略提供重要的理论依据。就有关放牧家畜甲烷气体的测定方法研究作了综述。

英文摘要：

CH4 emissions from ruminants result in not only a loss of metabolic energy, it is also a greenhouse gas and as such significantly contributes to atmospheric warming. As such, it is important to research the sources and sinks of greenhouse gases in natural grassland ecosystems in order to highlight options which can be empioyed to mitigate the problem. This article reviews the methods used to measure methane emissions from graz ing animals.
