湿地甲烷释放研究进展

Advance in the Research on Methane Emissions from Wetlands

甲烷是一种重要的温室气体，近年来大气甲烷浓度显著增加，湿地甲烷释放量约占全球总释放量的２１％，因而是大气甲烷的主要来源之一。本文综述了湿地甲烷产生、释放和氧化过程以及影响因素，以便为国内湿地甲烷排放研究提供借鉴。

Methane(CH 4) is an important greenhouse gas.Its concentration in the atmosphere has increased greatly in recent years.Accounting for about 21% of global methane emission,wetland methane emission is one of the main sources of atmospheric methane.In order to provide reference for domestic study of wetland methane emission,this paper reviewed the processes involved in wetland methane production,emission and oxidation and factors affecting them.
