本文定义了英国多年生能源作物的潜在可用土地，作为“2050年英国生物能源空间建模”项目进行的更广泛评估的第一部分。在GIS中结合七个主要约束条件的数据，将可用面积减少到900多万公顷（占GB的40%）。加上其他基于土地覆盖自然度分数的限制来代表景观考虑，最终面积为8.5 M ha（占GB的37%）。这种分布与2001-2011年英国能源作物计划下种植的芒草和SRC柳的位置进行了比较，发现83%的种植落在规定的可用土地上。这种对应关系使人们相信，分析中所考虑的因素与以前的种植决定大致一致。
This paper defines the potentially available land for perennial energy crops across Great Britain as the first component of a broader appraisal undertaken by the ‘Spatial Modelling of Bioenergy in Great Britain to 2050’ project. Combining data on seven primary constraints in a GIS reduced the available area to just over 9 M ha (40% of GB). Adding other restrictions based on land cover naturalness scores to represent landscape considerations resulted in a final area of 8.5 M ha (37% of GB). This distribution was compared with the locations of Miscanthus and SRC willow established under the English Energy Crop Scheme during 2001–2011 and it was found that 83% of the planting fell within the defined available land. Such a correspondence provides confidence that the factors considered in the analysis were broadly consistent with previous planting decisions.
