森林对人类社会至关重要，提供多种重要的生态系统服务。人们认为生物多样性会对多种服务产生积极影响，但来自与管理相关的自然系统规模的证据很少。在这里，在 400,000 平方公里的范围内，我们报告说，生产林中的树种丰富度与多种生态系统服务呈正向驼峰形关系。其中包括树木生物量的生产、土壤碳储存、浆果生产和野味生产潜力。例如，五种树种的生物量产量比一种树种高约 50%。此外，我们还发现树种丰富度与其他生物多样性组成部分之间存在正相关关系。重要的是，没有任何单一树种能够促进所有服务，并且某些服务彼此呈负相关。因此，生产林的管理将受益于考虑多种树种，以维持社会从森林中获得的全方位利益。树木多样性被认为有益于森林生态系统，但大规模研究的证据很少。这项针对 40 万平方公里森林面积的研究表明，较高的树种丰富度支持更高水平的多种生态系统服务，因此也支持生产林的更可持续管理。
Forests are of major importance to human society, contributing several crucial ecosystem services. Biodiversity is suggested to positively influence multiple services but evidence from natural systems at scales relevant to management is scarce. Here, across a scale of 400,000 km2, we report that tree species richness in production forests shows positive to positively hump-shaped relationships with multiple ecosystem services. These include production of tree biomass, soil carbon storage, berry production and game production potential. For example, biomass production was approximately 50% greater with five than with one tree species. In addition, we show positive relationships between tree species richness and proxies for other biodiversity components. Importantly, no single tree species was able to promote all services, and some services were negatively correlated to each other. Management of production forests will therefore benefit from considering multiple tree species to sustain the full range of benefits that the society obtains from forests. Tree diversity is thought to benefit forest ecosystems, but evidence from large-scale studies is scarce. This study of a 400,000 km2 forest area shows that higher tree species richness supports higher levels of multiple ecosystem services, and therefore also a more sustainable management of production forests.
