摘要
甲烷作为仅次于二氧化碳的全球第二大温室气体,其排放带来的温室效应相当于CO_(2)的25倍,故畜禽排放甲烷浓度增加导致温室效应已越来越受到全球的重视。农业领域畜牧养殖过程中,饲养牛排放甲烷量居多,而牛舍甲烷排放主要来源于牛后肠道排气、打嗝或粪便等有机物无氧分解过程中产生。因甲烷减排是降低全球温室效应的有效途径之一,故对牛舍甲烷监测的准确性是实现甲烷减排的基础。因此,为提高畜牧养殖经济和环境的双重效益,针对国内外牛舍甲烷浓度监测技术的研究情况进行综述。
In recent years,the annual increase of global greenhouse gas emissions has led to the increase of global temperature.As the second largest greenhouse gas in the world after carbon dioxide,methane emissions have brought about a greenhouse effect equivalent to 25 times of CO_(2).The greenhouse effect caused by the increase of methane concentration from livestock and poultry emissions has attracted more and more global attention.In the process of animal husbandry in the agricultural field,the amount of methane released from beef steaks is mostly,while the methane emission from cowshed mainly comes from the anaerobic decomposition of organic substances such as intestinal fermentation,burping and farting,or feces.Methane emission reduction is one of the effective ways to reduce the global greenhouse effect,and the accuracy of methane monitoring in cowshed is the basis for methane emission reduction.Therefore,in order to improve the dual benefits of animal husbandry economy and environment,the research situation of methane concentration monitoring technology in cowshed at home and abroad is briefly reviewed.
