摘要:

科学合理地评估茶叶产品碳足迹有助于促进环境保护,推动茶业可持续发展。本研究旨在通过建立茶树生物量估算模型,计算茶树在种植经营阶段的碳汇量,并结合茶叶在生产加工和分销运输过程中的碳排放量,评估茶叶从“摇篮到大门”的生命周期碳足迹,以估算丽水市2015—2023年茶叶产品的碳排放量。结果表明:茶树地上生物量、地下生物量和总生物量模型决定系数(R2)均高于0.80;茶树年均碳储量效益平均为10.57 kg·kg-1(以CO2排放当量计,CO2-eq);茶叶产品平均碳足迹为0.49 kg·kg-1(以CO2-eq计);2015—2023年丽水市茶叶产品生产的平均碳排放量为2 133 t(以CO2-eq计),平均碳排放强度分别为0.41 t·hm-2。茶树年均碳储量效应高于茶园经营阶段碳排放量,茶树碳储量效应在茶叶产品碳足迹评估中有着重要的作用;2015—2023年丽水市茶叶产品碳排放量呈逐年上升趋势,松阳、遂昌碳排放强度最高。本研究结果可为相关研究提供思路,为茶叶低碳生产提供理论依据。

Abstract:

Scientifically and reasonably assessing the carbon footprint of tea products helps to promote environmental protection and drive the sustainable development of the tea industry. This study aimed to evaluate the life cycle carbon footprint of tea products from “cradle to gate” in Lishui City by establishing a tea plant biomass estimation model to calculate carbon sequestration during the cultivation stage, combined with carbon emissions from processing and distribution. The results showed that: The R2 values for above-ground, below-ground, and total biomass models all exceed 0.80; The average annual carbon storage benefit of tea plants was 10.57 kg·kg-1(CO2-eq); The average carbon footprint of tea products was 0.49 kg·kg-1(CO2-eq); From 2015 to 2023, the average annual carbon emissions from tea production in Lishui reached 2 133 t (CO2-eq), with an average emission intensity of 0.41 t·hm-2. The study revealed that the annual carbon storage effect of tea plants exceeds cultivation-stage emissions, playing a significant role in tea product carbon footprint assessment. Moreover, tea product carbon emissions in Lishui showed an increasing trend from 2015 to 2023, with Songyang and Suichang counties exhibiting the highest emission intensity. This research provided methodological insights for related studies and theoretical support for low-carbon tea production.
