摘要
水稻产后造成的数量损失,意味着水稻在损失前产生的碳排放失去经济效益,成为无效碳排放。文章立足于水稻产后损失和无效碳排放的测算,通过梳理水稻产后损失与碳排放的关联关系,构建系统动力学模型,探究水稻产后减损的碳减排效应。研究发现:水稻在从田头到餐桌的流通过程中,水稻损失的数量累积性增加,无效碳排放总量不断增加。其中,稻米加工环节的数量损失最多,是水稻产后减损和无效碳排放减排的关键环节。通过增加同等碳排放规模下顺利进入消费端的稻米数量是有效的碳减排措施。
Post-harvest losses in rice production result in a significant decrease in quantity,which means that the carbon emission generated during rice production before the losses is economically inefficient,thus becoming ineffective carbon emissions.This article focuses on estimating the extent of post-harvest losses and ineffective carbon emission in rice production.By analyzing the relationship between post-harvest losses and carbon emission,a comprehensive systemic dynamics model is developed to explore the carbon emission reduction effects of reducing post-harvest losses in rice production.The research findings reveal that the losses in rice production accumulate throughout the entire supply chain,from field to table,leading to a continuous increase in ineffective carbon emissions.Specifically,the processing stage of rice accounts for the largest proportion of loss and is crucial in reducing post-harvest losses and ineffective carbon emissions.One effective measure to reduce carbon emissions is to increase the quantity of rice reaching the consumer market while maintaining the same carbon emission level.
