摘要
甲烷被认为是仅次于ＣＯ＿２的具有温室效应的气体．在农业生态系统中，稻田是甲烷的主要来源．讨论稻田甲烷排放量、排放机制，提出减少稻田甲烷排放的控制措施，对控制稻田生态效益提供依据．此外，本文结合稻田生态效益提高途径进行科学认识．
Methane is a radiactively active gas like CO,but it has a further effect. The largest emission of methane in agroecosystems occtlrs from rice paddies.This paper discusses methane emission from rice paddies,emission mechanism and some control measures.These analysis is very significance to improve the ecological impact of rice paddies.
