摘要栖息地的破坏导致了当前的生物多样性灭绝危机，它损害了人类从正常运作的生态系统中获得的基本利益或生态系统服务。保护物种和生态系统服务可以通过共同的解决方案来实现。然而，目前还不清楚这两个主要的保护目标是否在全世界范围内广泛一致，以使这两个目标的全球战略能够获得协同作用。在本文中，我们评估了这两个目标之间的一致性，探讨了不同地区的一致性如何变化，并研究了同时保护生物多样性和生态系统服务的全球潜力。我们发现，已公布的全球生物多样性保护优先地图港口估计陆地生态系统服务价值（ESV）的不成比例的份额。生物多样性优先事项和环境价值重叠的情况因区域而异，在生物多样性优先事项高但环境价值低的地区，需要采取专门的养护办法。然而，总的来说，我们的研究结果表明，保护生物多样性和生态系统服务的机会。敏感性分析表明，结果是强大的可用ESV数据的已知限制。要利用这些机会，就需要在细微的尺度上确定协同作用，并开发经济和政策工具来利用这些机会。
ABSTRACT Habitat destruction has driven much of the current biodiversity extinction crisis, and it compromises the essential benefits, or ecosystem services, that humans derive from functioning ecosystems. Securing both species and ecosystem services might be accomplished with common solutions. Yet it is unknown whether these two major conservation objectives coincide broadly enough worldwide to enable global strategies for both goals to gain synergy. In this article, we assess the concordance between these two objectives, explore how the concordance varies across different regions, and examine the global potential for safeguarding biodiversity and ecosystem services simultaneously. We find that published global priority maps for biodiversity conservation harbor a disproportionate share of estimated terrestrial ecosystem service value (ESV). Overlap of biodiversity priorities and ESV varies among regions, and in areas that have high biodiversity priority but low ESV, specialized conservation approaches are necessary. Overall, however, our findings suggest opportunities for safeguarding both biodiversity and ecosystem services. Sensitivity analyses indicate that results are robust to known limitations of available ESV data. Capitalizing on these opportunities will require the identification of synergies at fine scales, and the development of economic and policy tools to exploit them.
