在农业用地上实施土壤有机碳固存（SCS）做法有可能有助于缓解全球一级的气候变化。然而，我们对葡萄栽培土壤对这一全球努力的贡献程度的了解仍然有限。在这项研究中，我们使用了随机森林回归预测土壤有机碳储量的变化在西欧葡萄园在五个SCS的做法：有机添加剂（OA），覆盖种植（CC），有机添加剂和免耕（OA+NT），免耕和覆盖种植（NT+CC），有机添加剂，免耕和覆盖种植（OA+NT+CC）的组合。为西欧的六个国家（西班牙、法国、意大利、葡萄牙、德国和奥地利）建立了每种SCS做法的减排率模型并绘制了地图。总体而言，OA+NT+CC（8.29 Mg CO2-eq.）ha-1 yr-1），而最低的是CC（7.03 Mg CO2-eq.）。ha−1yr−1）。结果表明，区域和国家一级的减排率存在重大差异。尽管存在这些差异，但在这六个国家，采用SCS做法具有很高的减排潜力，应鼓励葡萄种植部门通过土壤碳固存抵消温室气体排放。
The implementation of soil organic carbon sequestration (SCS) practices on agricultural land has the potential to help to mitigate climate change at the global level. However, our understanding of the extent to which viticultural soils can contribute to this global effort remains limited. In this study, we used a random forest regression to predict the change in soil organic carbon stocks in vineyards of Western Europe under five SCS practices: organic amendments (OA), cover cropping (CC), organic amendments and no-tillage (OA+NT), no-tillage and cover cropping (NT+CC), and a combination of organic amendments, no-tillage and cover cropping (OA+NT+CC). The abatement rate of each SCS practice was modelled and mapped for six countries in Western Europe: Spain, France, Italy, Portugal, Germany and Austria. Overall, the highest abatement rate was reached under OA+NT+CC (8.29 Mg CO2-eq. ha−1yr−1), whereas the lowest was observed under CC (7.03 Mg CO2-eq. ha−1yr−1). Results showed major differences in abatement rates at the regional and national level. Despite these differences, the adoption of SCS practices was associated with a high abatement potential in the six countries and should be encouraged in the viticulture sector as a way to offset greenhouse gas emissions via soil carbon sequestration.
