生物多样性丧失和气候变化的全球影响相互关联，但它们之间的反馈很少得到评估。树木多样性更大的地区往往更有生产力，提供更大的碳汇，生物多样性的丧失可能会减少这些天然碳汇。在这里，我们量化树木和灌木物种丰富度如何影响生物群落，国家和区域尺度上的生物量生产。我们发现，温室气体减排可以帮助保持树木的多样性，从而避免9-39%的减少，在不同的生物群落，否则可能会发生在未来50年的陆地初级生产力。将因气候变化而遭受最大经济损失的国家将从保护树木多样性和初级生产力中获益最多，这有助于减缓气候变化。我们的研究结果强调了气候，生物多样性和社会三赢的机会，并强调这些共同利益应该是重新造林计划的重点。
The global impacts of biodiversity loss and climate change are interlinked, but the feedbacks between them are rarely assessed. Areas with greater tree diversity tend to be more productive, providing a greater carbon sink, and biodiversity loss could reduce these natural carbon sinks. Here, we quantify how tree and shrub species richness could affect biomass production on biome, national and regional scales. We find that GHG mitigation could help maintain tree diversity and thereby avoid a 9–39% reduction in terrestrial primary productivity across different biomes, which could otherwise occur over the next 50 years. Countries that will incur the greatest economic damages from climate change stand to benefit the most from conservation of tree diversity and primary productivity, which contribute to climate change mitigation. Our results emphasize an opportunity for a triple win for climate, biodiversity and society, and highlight that these co-benefits should be the focus of reforestation programmes.
