Abstract: Water is one of the key factors affecting CH₄ emission in wetlands. To investigate effects of soil moisture content and litters on CH₄ emission,an indoor incubation experiment was performed using peat collected from the Zoige Wetlands. The experiment was designed to have three treatments in soil moisture content Treatment 60%（ unsaturated soil moisture,60% of soil water holding capacity）,Treatment 100%（ saturated soil moisture,100% of soil water holding capacity） and Treatment WDA（ wetting-drying alternation） and two treatments in litter（ with or without litters addition）.Results show that the effects of soil moisture and litters on CH₄ emission from the peat were significant. Compared to Treatment 60%,Treatment WDA was significantly higher and Treatment 100% the highest in CH4 emission. Addition of litters promoted CH₄ emission rate and cumulative emission in peat. CH₄ emission from the peat responded the most quickly to litters addition in Treatment 100%,not so quickly in Treatment WDA and the slowest in Treatment 60%.
