本文对水田甲烷排放通量的研究进展及有关的土壤和环境因素作了综述。
The advances in the research of methane emission from rice paddies and related soil properties and environmental factors are reviewed.
结果表明：在水稻生医季节甲烷排放通量变化很大，在分蘖期和成熟期一般会出现峰值。
The results show a great variation in methane emission during the rice growing season, and the peak values appear during tillering period and fruiting period.
早稻甲烷排放峰值出现在水稻幼穗分化期，晚稻种稻期间甲烷排放通量在水稻分蘖盛期最大。
The methane emission peak of early rice appeared in young panicle differentiation stage of rice.
