描述了土壤碳和土地利用数据库的汇编，从中可以运行整个英国(UK)的土壤二氧化碳排放模型。该数据库给出了0-30厘米和30-100厘米深度的土壤有机碳、沙子、粉土和粘土含量以及按参考层加权的体积密度。这些数据是根据英国1公里网格上的土壤类型和土地利用信息插入的，用于估计土壤碳储量。1990年，也就是《京都议定书》关于碳排放的基准年，估计英国土壤表层1米的有机碳总量为4562Tg，平均密度为18 kg m(-2)。数据可以按层(如表土54%)和国家(如苏格兰的48%)以及土壤和土地类型报告。
The compilation of a database of soil carbon and land use is described, from which models of soil carbon dioxide emissions across the United Kingdom (UK) can be run. The database gives soil organic carbon, sand, silt and clay contents and bulk densities weighted to reference layers from 0 to 30 cm and from 30 to 100 cm depths. The data are interpolated from information on soil types and land use on a 1 km grid across the UK and are used to estimate soil carbon stocks. For 1990, the baseline year for the Kyoto Protocol on carbon emissions, the estimate is 4562 Tg soil organic carbon in the top 1 m of soil across the UK, with an average density of 18 kg m(-2). The data can be reported by layer (e.g. 54% in topsoils) and country (e.g. 48% in Scotland) as well as by soil and land type.
