摘要
农作物秸秆综合利用在温室气体减排中发挥着重要作用.我国推进秸秆资源化利用的主要突破点是主粮作物(如水稻、玉米和小麦).基于2019年国家统计年鉴数据,根据我国主要农作物产量核算秸秆量,通过综述文献,确定了各种农作物秸秆利用和处理方法的温室气体排放量,通过情景模拟预测了作物秸秆利用与处理过程中温室气体排放的变化趋势.结果表明,5种情景条件下秸秆综合利用的碳排放将增加-40％～14％.未来,需做好秸秆还田的有效控制,进一步减少碳排放,实现碳中和目标.
Abstract
The comprehensive utilization of agricultural straw plays an important role in greenhouse gas emission reduction.The main breakthrough point for promoting straw resource utilization in China is the staple crops(rice,corn and wheat).The study is based on the 2019 National Statistical Yearbook data,which accounts for straw production based on China's main crop production.Through reviewing papers,greenhouse gas emissions from various crop straw utilization and treatment methods were determined,and the trends of greenhouse gas emissions during crop straw utilization and treatment were predicted through scenario simulation.The results showed that the carbon emissions from integrated straw utilization increased by-40％-14％under the five scenarios.In the future,it is necessary to effectively control straw returning to the field,further reduce carbon emissions,and achieve carbon neutrality.
