Synergistically maintain or enhance the numerous beneficial contributions of nature to the quality of human life is an important but challenging question for achieving Sustainable Development Goals. However, the spatiotemporal distributions of global nature's contributions to people (NCPs) and their interactions remain unclear. We built a rapid assessment indicator framework and produced the first spatially explicit assessment of all 18 NCPs at a global scale. The 18 global NCPs in 1992 and 2018 were globally assessed in 15,204 subbasins based on two spatial indicator dimensions, including nature's potential contribution and the actual contribution to people. The results show that most of the high NCP values are highly localized. From 1992 to 2018, 6 regulating NCPs, 3 material NCPs, and 2 nonmaterial NCPs declined; 29 regulating-material NCP combinations (54 in total) dominated 76% of the terrestrial area, and the area with few NCPs accounted for 22%; and synergistic relationships were more common than tradeoff relationships, while the relationships among regulating and material NCPs generally traded-off with each other. Transitional climate areas contained few NCPs and have strong tradeoff relationships. However, the high synergistic relationship among NCPs in low latitudes could be threatened by future climate change. These findings provide a general spatiotemporal understanding of global NCP distributions and can be used to interpret the biogeographic information in a functional way to support regional coordination and achieve landscape multifunctionality for the enhancement of human well-being.
协同维护或增强大自然对人类生活质量的诸多有益贡献，是实现可持续发展目标的一个重要但具有挑战性的问题。然而，全球自然对人类的贡献（NCP）的时空分布及其相互作用仍不清楚。我们构建了一个快速评估指标框架，并在全球范围内首次对所有 18 项 NCP 进行了空间显式评估。基于两个空间指标维度，包括自然的潜在贡献和对人类的实际贡献，对 1992 年和 2018 年全球 15204 个亚流域的 18 项全球 NCP 进行了评估。结果表明，大多数高 NCP 值高度本地化。1992 年至 2018 年，有 6 项调节 NCP、3 项物质 NCP 和 2 项非物质 NCP 下降；29 项调节-物质 NCP 组合（共 54 项）占陆地面积的 76%，NCP 较少的面积占 22%；协同关系比权衡关系更为常见，而调节和物质 NCP 之间的关系通常相互权衡。过渡气候区 NCP 较少，且具有强烈的权衡关系。然而，低纬度地区 NCP 之间的高协同关系可能会受到未来气候变化的威胁。这些发现提供了对全球 NCP 分布的一般时空理解，可以用来以功能方式解释生物地理信息，以支持区域协调，实现景观多功能性，从而提高人类福祉。
