主　　题：Biochar Methane mitigation Methanogens Methanotrophs 

摘      要：Biochar has been reported to mitigate short-term methane(CH4)emissions from paddy ***,CH4 mitigation by biochar has primarily focused on the abundance and variations of methanogens and methanotrophs,and changes in their activities during methane production and ***,long-term effects of biochar on methane mitigation from paddy soil remain *** review overviewed the existing mechanisms for CH4 mitigation as a result of biochar *** addition,the two existing opinions on the long-term CH4 mitigation effect upon biochar application were *** the already explored mechanisms of fresh biochar on CH4 mitigation from paddy soil and a novel discovery,the potential mechanisms of biochar on long-term methane emission response were *** review also revealed the uncertain responses of biochar on long-term CH4 ***,to achieve carbon neutral goal,it is important to further explore the mechanisms of long-term CH4 mitigation under biochar application.
