大规模生物质种植园（BP）通常被认为是一种可行且安全的气候工程方案，用于从大气中提取碳，从而降低全球平均温度。然而，这种陆地二氧化碳清除战略的能力及其对地球系统的更大影响仍有待全面研究，在碳排放量增加和气候变化不断加剧的情况下更是如此。在这里，我们使用一个空间上明确的过程为基础的生物圈模型，系统地量化的潜力和权衡的范围内的BP情景专用于tCDR，代表不同的假设哪些领域是可转换的。基于一个温和的CO2浓度路径，到本世纪末，全球平均变暖将比工业化前水平高2.5 ° C--类似于代表性浓度路径（RCP）4.5 --我们假设tCDR将在2038年变暖1.5 ° C时实施。我们的研究结果表明，只有在排放量同时减少的情况下，BP才能充分减缓大气中累积碳的增加，就像RCP4.5轨迹一样。tCDR平衡额外的、不减的排放量的潜力，
Large-scale biomass plantations ( BPs ) are often considered a feasible and safe climate engineering proposal for extracting carbon from the atmosphere and, thereby, reducing global mean temperatures. However, the capacity of such terrestrial carbon dioxide removal ( tCDR ) strategies and their larger Earth system impacts remain to be comprehensively studied — even more so under higher carbon emissions and progressing climate change. Here, we use a spatially explicit process-based biosphere model to systematically quantify the potentials and trade-offs of a range of BP scenarios dedicated to tCDR, representing different assumptions about which areas are convertible. Based on a moderate CO 2 concentration pathway resulting in a global mean warming of 2.5 ° C above preindustrial level by the end of this century — similar to the Representative Concentration Pathway ( RCP ) 4.5 — we assume tCDR to be implemented when a warming of 1.5 ° C is reached in year 2038. Our results show that BPs can slow down the progression of increasing cumulative carbon in the atmosphere only suf fi ciently if emissions are reduced simultaneously like in the underlying RCP4.5 trajectory. The potential of tCDR to balance additional, unabated emissions leading towards a
