Methane research has attracted much attention of the scientific community, not only in that its contribution to global warming is second only to carbon dioxide, but also because the value-added potential of single molecule methane is 15-30 times that of carbon dioxide. As a unique ecosystem, wetland is the “source” of methane (CH 4 ), which is an important greenhouse gas in the atmosphere. Methane emission from wetlands is the result of the combined effects of methane production, transport and oxidation processes, in which methane production is the prerequisite for methane emission. This paper studied the effects of different factors on methane production in wetlands, including methanogens and methanotrophs, substrate, temperature, soil water, pH, and vegetation, in order to find out the main factors that affect methane emission from wetlands and their influence degree so that could provide some reference for the estimation and prediction of global greenhouse effect.
