摘要: 甲烷是主要的温室气体之一,对温室效应的贡献仅次于CO2,而每分子甲烷温室增温潜力是CO2的21倍.因此确定全球大气甲烷的源与汇,并对其进行估算、预测已成为目前全球环境变化及温室效应研究的一个热点.本文概述了国内外大气甲烷源与汇研究的进展情况,详述了土壤氧化(吸收)大气与内源甲烷机理及其影响因子(如土地利用情况、环境甲烷浓度、土壤温度、湿度、pH值、孔隙状况等).最后指出,通过在长白山森林垂直分布带开展地带性土壤甲烷氧化(吸收)研究,对估算我国温带至寒带、高山苔原带土壤吸收甲烷总量,乃至全球甲烷汇具有重要意义.

Abstract: 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 importand focus concerning the researches on global change and greenhouse effect. This paper summarized the researches on the cources and sinks of CH4,and amplified on the influential factors (e.g.land use,ambient atmospheric CH4 concentration,soil temperature,soil moisture content,soil pHand 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.
