摘要

摘要:甲烷是一种重要的温室气体。畜牧业生产构成了英国甲烷排放总量的很大一部分。通过比较牲畜产生的甲烷与三种理论汇,评估了平衡甲烷生产与直接消费的可能性。反刍家畜生产占英国甲烷排放量的40%。随着温室气体排放的环境和经济成本的增加,必须探索平衡排放与消费的方法。研究了反刍家畜产生的甲烷的三种假设的汇。在现代农业的背景下,只有一个水槽是可行的。在最佳条件下,在持续提供高浓度甲烷(>1%)的土壤中,高容量甲烷氧化可以明显减少甲烷排放。

Methane production and theoretical consumption in UK livestock production: is a realistic balance possible?

Context abstract: Methane is an important greenhouse gas. Livestock production constitutes a large part of total UK methane emission. By comparing livestock derived methane production with three theoretical sinks, the possibility of balancing methane production with direct consumption is assessed.

Ruminant livestock production contributes up to 40% of methane emission in the UK. With the increasing environmental and economic costs of greenhouse gas release, ways in which emission can be balanced with consumption must be explored. Three hypothetical sinks for ruminant livestock derived methane were examined. Only one sink appeared at all practicable in the context of modern farming. Under optimal conditions, high capacity methane oxidation in soil could conceivably reduce methane emissions where high concentrations of methane (>1%) were consistently supplied.
