摘　　要：使用APSIM作物模型,模拟1981−2014年华北平原夏玉米、冬小麦−夏玉米、冬小麦−夏玉米−早播玉米1(提前10d)、冬小麦−夏玉米−早播玉米2(提前20d)四种种植模式下土壤有机碳(SOC)变化、土壤氧化亚氮(N_(2)O)排放、土壤温室气体排放和产量的变化。结果表明:四种种植模式中,1981−2014年华北平原夏玉米种植模式下土壤N_(2)O排放量最小(514.81kg·hm^(−2))、土壤主要温室气体平均排放量最少(0.30MgCO_(2-eq)·hm^(−2));冬小麦−夏玉米−早播玉米1(提前10d)种植模式下土壤有机碳平均变化量最少,为120.78kg·hm^(−2);冬小麦−夏玉米−早播玉米2(提前20d)种植模式的土壤主要温室气体平均排放量次之,为0.76MgCO_(2-eq)·hm^(−2);四种种植模式中,冬小麦−夏玉米种植模式的平均产量最高,为23405.47kg·hm^(−2);夏玉米种植模式下土壤主要温室气体排放效应最好(GHG=0.02 MgCO_(2-eq)·hm^(−2)),冬小麦−夏玉米−早播玉米2(提前20d)种植模式次之(GHG=0.04 MgCO_(2-eq)·hm^(−2));在保证产量的前提下,考虑粮食安全、资源节约和环境友好各方面,冬小麦−夏玉米−早播玉米2(提前20d)两年三熟种植模式是华北平原较为理想的种植制度。The APSIM crop model was used to simulate the changes of soil organic carbon(SOC),soil nitrous oxide(N_(2)O)emissions,soil greenhouse gas emissions and yield in the North China Plain from 1981 to 2014 under summer maize,winter wheat-summer maize,winter wheat-summer maize-early maize 1(10 days in advance),winter wheat-summer maize-early maize 2(20 days in advance)four cropping patterns.The results showed that among the four cropping patterns,the soil N_(2)O emission in summer maize planting mode was the lowest,which was 514.81kg·ha^(−1),the average greenhouse gas emission of soil was 0.30MgCO_(2-eq)·ha^(−1).The average change of soil organic carbon in winter wheat-summer maize-early maize1(10 days in advance)cropping pattern was the least,which was 120.78kg·ha^(−1).The average greenhouse gas emission of winter wheat-summer maize-early maize(20 days in advance)was 0.76MgCO_(2-eq)·ha^(−1).Among the four planting patterns,the average yield of winter wheat-summer maize was the highest,which was 23405.47kg·ha^(−1),the summer maize planting pattern had the best effect on soil greenhouse gas emissions(GHG=0.02 MgCO_(2-eq)·ha^(−1)),followed by the winter wheat-summer maize-early maize 2(20 days advance)planting pattern(GHG=0.04 MgCO_(2-eq)·ha^(−1)).On the premise of ensuring the yield,considering the aspects of food security,resource conservation and environmental friendliness,the planting pattern of winter wheat-summer maize-early maize 2(20 days in advance)will be an ideal planting system in the North China Plain.
