论文摘要
土壤有机碳（SOC）在改善土壤条件和土壤功能方面起着重要作用。不断增加的土地使用变化导致SOC含量在全球范围内的重要下降。已经提出，增加了农业土壤中的SOC作为减轻气候变化的策略。动物粪便具有丰富SOC的特征，当应用于作物场时，同时，它可能构成农作物的天然肥料。在本文中，使用西班牙加泰罗尼亚地区作为地中海特征性低社会的案例研究进行了模拟，以检查动物粪便在用作有机肥料时是否可以大大改善农业领域的SOC。我们的结果表明，只有使用运输到田地的粪便，只能部分实现4x1000策略的政策目标。这意味着所提出的方法需要与其他策略相结合。
Soil organic carbon (SOC) plays an important role on improving soil conditions and soil functions. Increasing land use changes have induced an important decline of SOC content at global scale. Increasing SOC in agricultural soils has been proposed as a strategy to mitigate climate change. Animal manure has the characteristic of enriching SOC, when applied to crop fields, while, in parallel, it could constitute a natural fertilizer for the crops. In this paper, a simulation is performed using the area of Catalonia, Spain as a case study for the characteristic low SOC in the Mediterranean, to examine whether animal manure can improve substantially the SOC of agricultural fields, when applied as organic fertilizers. Our results show that the policy goals of the 4x1000 strategy can be achieved only partially by using manure transported to the fields. This implies that the proposed approach needs to be combined with other strategies.
