中文摘要：
针对全球气候变化日趋剧烈、我国化学氮肥利用率低、农作物秸秆和畜禽粪便大量废弃、环境污染比较严重的现状，本研究提出采用农业生物质循环利用种植模式实现固碳减排，提高氮肥利用率，减少面源污染，发展低碳农业。运用生命周期评价体系，比较秸秆配施有机肥、添加微生物肥料、堆肥复合肥配施化肥等多种有机肥配施种植模式下，综合观测我国典型粮食作物稻-麦轮作生态系统中CO2、CH4和N2O的排放规律；估算化肥、农药、田间操作管理等引起的碳排放；在当季作物时间尺度上根据生态系统呼吸、初级光合生产力、收获物、生物质投入等碳分量，计算农田生态系统碳收支及其固碳潜力。进而综合评估多种农业生物质循环利用种植模式的综合温室效应、综合净温室效应及其与产量指标相结合的温室气体排放强度，填补国内外当季作物化肥、有机肥配施种植模式下稻田综合净温室效应比较研究的空白，为实现我国2020年温室气体减排目标提供新的理论依据和技术支持。
