反刍动物甲烷排放量测定方法的研究进展

Research Advance in Measurement Methods of Methane Emission from Ruminants

全球环境问题日益突显,温室气体严重威胁着气候。甲烷为温室气体的第二大成分,并且其温室效应远大于二氧化碳(温室气体第一大成分),其排放量直接影响大气环境,同时反刍动物如牛羊体内甲烷的产生排放也造成了饲粮能量损耗,甲烷减排成为人们关注的热点问题。确定甲烷减排,其测量方法是首先要明确的,本文将对反刍动物甲烷排放量的测定方法进行综述,以期为研究甲烷减排措施提供参考。

Global environmental issues are increasingly prominent,and greenhouse gases are a serious threat to the climate.Methane is the second largest component of greenhouse gases,and its greenhouse effect is much larger than carbon dioxide(the largest component of greenhouse gases).Its emissions directly affect the atmos⁃pheric environment.At the same time,methane emissions from ruminants such as cattle and sheep also cause diet energy loss and methane emission reduction have become hot issues of global concern.To determine the methane emission reduction,the measurement method must first be clear.This article reviewed the measure⁃ment methods of ruminant methane emission in order to provide a reference for the study of methane emission reduction measures.
