摘要
随着全球人口的增长,人类活动的加剧,使得大气中温室气体的含量成倍增加,全球变暖已经成为全世界所关注的热点,甲烷作为一种重要的温室气体,对大气增温的作用仅次于二氧化碳。目前全球每年排放的甲烷总量为5.35×108t,其中人类活动产生的甲烷排放量为3.75×108t。作者主要阐述了甲烷对温室效应的影响机理和作用,并论述了减排甲烷的意义及措施。
The content of greenhouse gases has been increased with the double of the world population and human activities. Global warming becomes a more popular topic problem. Greenhouse effect of methane is only inferior to carbon dioxide. At present the total discharge volume of methane to the air is 5.35×10 8 t, about 3.75×10 8 t due to the human activities. In this paper, the authors expounded the mechanism and function of methane to the greenhouse effect and the meaning and measures for reducing methane.
