| 摘 要： | 明确小麦-夏直播花生(W-P)种植体系的主要碳排放环节,可为采取有效措施实现该体系高产与低碳排放的协同效益提供参考.本文依据全生命周期方法,构建碳足迹模型,并核算了山东省W-P种植体系生命周期碳排放.结果表明:山东省W-P种植体系的净收益较小麦-玉米(W-M)种植体系高71.2%~88.3%;W-P种植体系的单位面积碳排放达6977.9~8018.5 kg·hm-2,较W-M种植体系高6.2%,但单位净产值的碳排放为每元0.23~0.28kg CO_2-eq,较W-M种植体系低37.4%~44.1%.综合2种种植体系的净收益和单位净产值碳排放发现,W-P种植体系可以实现高产出与低碳排放的协同效益,符合优化供给、提质增效、农民增收的农业供给侧结构性改革目标.

| Abstract: | Clarifying the carbon emissions in wheat-summer direct-seeding peanut planting (W-P) system could help realize the synergistic effects of high yield and low carbon emissions. Based on whole life cycle method, we constructed a carbon footprint model to calculate the carbon emissions of W-P system. We found that the net income of W-P system was 71.2%-88.3% higher than that of wheat-maize rotation (W-M) system. The carbon emissions per unit area under W-P system was 6977.9-8018.5 kg·hm-2, being 6.2% higher than that of W-M system. The carbon emission of per net income under W-P system was 0.23-0.28 kg CO2-eq·yuan-1, which was 37.4%-44.1% lower than that of W-M system. Combining the net income and carbon emissions of per net income, W-P system could achieve synergistic effects of high yield and low carbon emissions, which would fulfill the targets of agricultural supply-side structural reform with optimizing supply, enhancing quality and efficiency, and increasing income of peasants. |
