[目的
]
了解江苏省农田生态系统近年来碳源碳汇的基本演变趋势,识别江苏省农业发展过程中的重要碳排放源,指导江苏农业低碳化发展。[方法
]
利用模型对农田碳排放量、碳吸收量及碳足迹进行测算,并对其动态变化进行分析。[结果
]
①江苏省农田生态系统碳排放总量总体趋向于增加,2001年江苏省碳排放量为4.44×10
6
t,2016年碳排放量为4.60×10
6
t,增幅为3.4%,化肥为碳排放的主要贡献因子。碳排放强度总体表现为下降趋势,各阶段碳排放强度均低于1 t/hm
2
。②碳吸收量总体呈现增加趋势,2001—2016年农作物总碳吸收量增加了3.57×10
7
t,年均复合增长率约为2.2%,单位面积碳吸收量呈整体增加趋势。园艺作物的碳吸收量明显高于粮食作物和经济作物。③农田生态系统碳足迹总体呈现降低趋势,存在较大的生态盈余。[结论
]
①2001—2016年江苏省农田生态系统的碳吸收量明显高于碳排放量,具有良好的固碳能力,农田生态系统呈现碳汇; ②农业投入物品对碳排放的影响程度不同,化肥是影响农业碳排放的最关键因子。
[Objective] To understand the basic evolutionary trend of carbon sources/sinks of farmland ecosystem of Jiangsu Provinc in recent years and identify the important sources of carbon emission in the process of agricultural development
in order to guide the development of low carbon agriculture.[Methods] The carbon estimation model was used to estimate the quantities of carbon emission
carbon uptake and carbon footprint
respectively. And the dynamic changes of the carbon footprint were analyzed.[Results] ① The total carbon emissions of farmland ecosystem tended to increase. The carbon emissions in 2016 (4.60×106 t) were increased by 3.4% compared to 2001 (4.44×106 t)
and fertilizer was the main contributor to carbon emission. The intensity of the carbon emission showed a decline trend
and it was lower than 1 t/hm2 at all stages. ② The carbon uptake showed an increasing trend. From 2001 to 2016
it increased by 3.57×107 t
the annual compound growth rate was about 2.2%
and the carbon uptake per unit area showed an overall increase trend. The carbon uptake of horticultural crops was significantly higher than that of food crops and cash crops. ③ The carbon footprint of farmland ecosystems showed a declining trend
and there was a large ecological surplus.[Conclusion] ① The quantities of carbon absorption of farmland ecosystem was significantly higher than carbon emission from 2001 to 2016
which showed that the farmland ecosystem had good carbon sequestration capacity and could be used as the carbon sink. ② The impact of agricultural inputs on carbon emission was different
and the fertilizer was the most critical factor affecting agricultural carbon emissions.
