背景：生物质已被确定为一种重要的可再生能源。然而，对专用能源作物日益增长的需求可能导致与粮食生产和生态系统服务的冲突。本研究采用嵌入地理信息系统的建模方法，在考虑社会、经济和环境约束的情况下，评估短轮作林地的空间供应。结果：结果表明，750万吨生物质（来自短轮伐灌木林）在英国是现实可用的。这种生产将需要80万公顷，而且几乎可以完全在质量差的边缘土地上种植。结论：因此，我们得出结论，短期轮作的森林能源作物在不影响环境可持续性或粮食生产的情况下，在满足英国可再生能源目标方面发挥重要作用。
Background: Biomass has been identified as an important source of renewable energy. However, growing demand for dedicated energy crops could lead to conflicts with food production and ecosystem services. This study uses a geographic information systems-embedded modeling approach to assess the spatial supply of short-rotation coppice, taking into account social, economic and environmental constraints. Results: Results suggest that 7.5 million tons of biomass (from short-rotation coppice) is realistically available in England. Such production would require 0.8 million ha and could be grown almost entirely on poor quality marginal lands. Conclusion: We therefore conclude that short-rotation coppice energy crops have the potential to play an important role in meeting UK renewable energy targets without compromising environmental sustainability or food production.
