绿色植物在大气甲烷循环中的作用

甲烷是引起气候变暖的一种重要温室气体,近年来一些研究发现陆地植物具有排放甲烷的能力,打破了植物仅为连通土壤-大气气体交换通道的原始理念,但由于其发生机理尚无法解释,也引起了人们的质疑。对绿色植物在大气甲烷循环中的作用进行了文献综述,对主要研究结果之间的差异进行了比较,同时就未来绿色植物在大气甲烷循环中的作用进行了阐述,拟为进行植物在地球甲烷循环中的功能及潜力的估测提供理论依据。

Effect of plant in atmosphere methane cycle

Methane is one of the main green house gases which can make the climate warming. The terrestrial plants have the ability in releasing the methane in the recent years, these researches are the challenge to the present theories which the terrestrial plants are the channel connecting the soil and atmosphere in releasing methane. This mechanism of theory is unknown and questioned. The effect of terrestrial plant on the methane cycle in the atmosphere, including comparison in different theories, the contribution in methane cycle in atmosphere by terrestrial plant in the future was discussed in order to provide the theories to evaluate the effect and the potential of terrestrial plant in the methane cycle.
