科学家揭示森林恢复方法对生物多样性和生态服务的影响

北京大学Fangyuan Hua和英国伦敦国王学院L. Adrian Bruijnzeel团队合作评估了森林恢复方法对生物多样性和生态系统服务的影响。2022年3月17日,国际学术期刊《科学》发表了这一成果。

在全球综合中,研究人员使用来自53个国家/地区264项研究包含的25,950个匹配数据评估了气候、土壤、水和木材生产服务的提供,以及对一系列人工林和原生森林中生物多样性进行了比较。原生森林可以更好地提供碳储存、供水,尤其是土壤侵蚀控制和生物多样性效益,而干旱地区成分更简单、更年轻的种植园则表现很差。然而,种植园在木材生产方面表现出优势。这些结果为政策制定者在履行森林恢复承诺时必须在环境和生产目标之间进行重要权衡提供了依据。

据悉,森林恢复正逐步在全球范围内开展,以提供关键的生态系统服务和生物多样性效益,但目前缺乏对不同恢复方法协同效益进行严格比较的数据。

Abstract: Forest restoration is being scaled-up globally to deliver critical ecosystem services and biodiversity benefits, yet we lack rigorous comparison of co-benefit delivery across different restoration approaches. In a global synthesis, we use 25,950 matched data pairs from 264 studies in 53 countries to assess how delivery of climate, soil, water, and wood production services as well as biodiversity compares across a range of tree plantations and native forests. Carbon storage, water provisioning, and especially soil erosion control and biodiversity benefits are all delivered better by native forests, with compositionally simpler, younger plantations in drier regions performing particularly poorly. However, plantations exhibit an advantage in wood production. These results underscore important trade-offs among environmental and production goals that policymakers must navigate in meeting forest restoration commitments.
