Intentionally allowing or promoting invasion by non-native trees into areas characterized by treeless vegetation could contribute to climate-change mitigation by increasing carbon (C) sequestration. In some areas of the world, incentives exist to retain invasive non-native trees in natural systems as a mechanism for increasing ecosystem C storage and reducing atmospheric carbon dioxide levels. Although this novel opportunity for C sequestration holds appeal, such an approach is problematic for several reasons: (1) invasive trees do not always increase net C sequestration due to greater occurrence of fire or reduced soil C; (2) lower albedo in invaded areas can increase absorption of solar radiation, thereby offsetting potential C sequestration; and (3) tree invasions often also have negative effects on biodiversity, economic opportunities, and water yield. Such drawbacks are sufficient to raise doubts about the widespread use of non-native tree invasions in treeless areas as a tool to ameliorate climate change.

是否应该在无树木的生态系统中使用树木入侵来缓解气候变化？

故意允许或促进非本地树木入侵以无树木植被为特征的地区，可以通过增加碳 (C) 固存来缓解气候变化。在世界的某些地区，存在鼓励在自然系统中保留侵入性非本地树木作为增加生态系统碳储存和降低大气二氧化碳水平的机制。尽管这种固碳的新机会很有吸引力，但由于以下几个原因，这种方法存在问题：(1) 由于火灾发生较多或土壤碳减少，入侵树木并不总是增加净固碳；(2) 入侵区域较低的反照率可以增加对太阳辐射的吸收，从而抵消潜在的碳封存；(3) 树木入侵通常也对生物多样性、经济机会、和产水量。这些缺点足以引起人们对在无树木地区广泛使用非本地树木入侵作为改善气候变化的工具的怀疑。
