摘要
种植业是主要的碳排放源,也是重要的碳固定汇。辽宁省作为我国重要粮食主产区,也是农业碳排放重点关注区域。为积极推动辽宁省种植业绿色低碳发展,该文估算了辽宁省种植业碳排放量,明确了不同来源碳排放的贡献程度,即农田 N;O 排放对辽宁省种植业碳排放的贡献最大,其次为稻田 CH;排放,并分析了当前辽宁省碳排放减排所面临的问题与挑战,提出了辽宁省种植业实现双碳目标的核心思路和具体的实施技术途径,以期为辽宁省早日实现双碳目标提供支撑参考。
The planting sector is one of the main sources of carbon emission and also the important pool of carbon sequestration. Liaoning province,as the major grain producing region in China,is also a key area of agricultural carbon emission. In order to promote the green and low-carbon development of planting in Liaoning province,this paper estimated the carbon emissions and determined the contribution from different sources,showing that N;O emissions from farmland accounted for the most followed by CH;emissions from paddy fields.Additionally,the problems and challenges of carbon emissions were analyzed and core ideas and specific approaches were put forward,providing support for achieving the double-carbon target in the planting industry of Liaoning province.
