[Advances in the research on sources and sinks of CH4 and CH4 oxidation (uptake) in soil].
Methane (CH4) is one of the main greenhouse gases contributing greenhouse effect, and its potential greenhouse effect is 21 times of CO2. Therefore, to determine the sources and sinks of atmospheric CH4 and to assess and forecast their amounts become and important focus concerning the researches on global change and greenhouse effect. This paper summarized the researches on the sources and sinks of CH4, and amplified on the influential factors (e.g. land-use, ambient atmospheric CH4 concentration, soil temperature, soil moisture content, soil pH and soil porosity) on atmospheric and interior CH4 oxidation in soil. It is significant that studying CH4 oxidation in vertical zonation soil in forests of Changbai Mountain to evaluate the CH4 consumption in forest soil.
