摘要
研究目的:构建粮食生产全周期碳收支体系,基于“动—静”结合视角测算黄河中下游粮食生产碳平衡水平,针对不同碳平衡水平分区提出差异化调控策略,可为全面反映粮食生产碳平衡水平、协同推进粮食绿色生产提供支持与参考。研究方法:生命周期评价法,碳转化系数法,经验公式法,静态平衡指数,动态平衡指数,信息熵模型。研究结果:(1)黄河中下游粮食生产碳排放和碳吸收均为增长趋势,空间上均呈“西北低,东南高”态势。(2)黄河中下游粮食生产碳收支静态平衡指数呈“西北低,东南高”分布,地区均值波动下降,各地市存在直升型、直降型、U型和倒U型4种演变趋势,粮食生产碳收支动态平衡指数具有显著时空异质性。(3)黄河中下游粮食生产碳平衡水平分区呈“西北失衡,东南平衡”分布,格局结构有序性历经“较有序—较无序—有序—无序”波动。研究结论:贡献度视角下黄河中下游部分地市粮食生产碳收支仍存在失衡情况,需进一步施行针对性和差异性的粮食绿色生产策略。
The purposes of this study are to construct a carbon budget system for the full cycle of food production,to measure the carbon balance level of food production in the middle and lower reaches of the Yellow River from the dynamic and static perspective,and to put forward differentiated control strategies through the zoning of the carbon balance level,to provide support and reference for comprehensively reflecting the carbon balance level of food production and synergistically promoting green food production.The research methods of life cycle assessment,carbon conversion coefficient method,empirical formula,static balance index,dynamic balance index and information entropy model are used.The results show that:1)carbon emissions and carbon sinks of food production in the middle and lower reaches of the Yellow River increase with a spatial trend of“low in the northwest and high in the southeast”.2)The static balance index of the carbon balance of food production in the middle and lower reaches of the Yellow River shows a distribution of“low in the northwest and high in the southeast”,with fluctuating and decreasing regional averages,and four types of evolutionary trends,including helicoidal,straight-down,U-shape and inverted U-shape,exist in each city.The dynamic balance index of the carbon balance of food production exhibits significant spatiotemporal variations.3)Carbon balance zoning of food production in the middle and lower reaches of the Yellow River are distributed as“imbalance in the northwest and balance in the southeast”,and the structural orderliness of the pattern fluctuates through“more ordered-less ordered-ordered-disordered”.In conclusion,there is still an imbalance in the carbon balance of food production in some cities in the middle and lower reaches of the Yellow River from the perspective of contribution,which requires further implementation of targeted and differentiated green food production strategies.
