本文通过对亚热带丘岗区稻田甲烷排放的实地测量和实验研究，描述了稻田甲烷的排放过程、排放量和排放特征；辩析了环境温度、施肥、水管理等因子对稻田甲烷排放的相关影响。提出了减少稻田甲烷排放的施肥方案和水管理措施。
Based on field measurements and experimental studies on methane emission from paddy fields in the subtropical hilly area, the process of methane emission, emissions and emission characteristics in paddy fields are described. Relevant impacts of environmental temperature, fertilization and water management on methane emission from paddy fields are analyzed . Proposed to reduce methane emissions from rice paddy and water management programs.
