生态系统支持生物多样性，也提供对人类有益的商品和服务。在设计保护和土地管理战略时，对生态系统服务最有价值的地点与支持生物多样性最多的地点的重合程度至关重要。然而，很少有研究可以作为关于生态系统服务与生物多样性之间可能的关联空间模式的结论的基础。此外，我们对结论对可用数据质量或用于分析的区域的选择和大小的敏感性知之甚少。在这里，我们首先以英国作为案例研究，提出对生态系统服务和生物多样性（受保护物种的丰富度）重要的区域的空间协方差的国家尺度估计。然后，我们探讨这些关联如何对可用数据的空间分辨率、我们研究区域的空间范围以及整个研究区域的区域变化敏感。我们的分析揭示了负关联和正关联的混合体。特别是，区域化分析表明，通过在不同地区，甚至在一个中等小岛屿内研究同一问题，可以得出关于生态系统服务与生物多样性之间关系的截然相反的结论。综合与应用。在政策背景下，生态系统服务与生物多样性之间关系的特定地点性质强调了多尺度环境决策的重要性，以反映当地条件和更广泛的优先事项。结果还表明，与更多的区域方法相比，建立生态系统服务和生物多样性一致性的一般模式的努力可能提供的建设性较小。
P> Ecosystems support biodiversity and also provide goods and services that are beneficial to humans. The extent to which the locations that are most valuable for ecosystem services coincide with those that support the most biodiversity is of critical importance when designing conservation and land management strategies. There are, however, few studies on which to base any kind of conclusion about possible spatial patterns of association between ecosystem services and biodiversity. Moreover, little is known about the sensitivity of the conclusions to the quality of the data available, or to the choice and size of the region used for analysis.Here, we first present national-scale estimates of the spatial covariance in areas important for ecosystem services and biodiversity (richness of species of conservation concern), using Britain as a case study. We then explore how these associations are sensitive to the spatial resolution of the available data, the spatial extent of our study region and to regional variation across the study area.Our analyses reveal a mixture of negative and positive associations. In particular, the regionalization analysis shows that one can arrive at diametrically opposing conclusions about relationships between ecosystem services and biodiversity by studying the same question within different areas, even within a moderately small island.Synthesis and applications. In a policy context, the location-specific nature of relationships between ecosystem services and biodiversity underscores the importance of multi-scale environmental decision-making, so as to reflect both local conditions and broader-scale priorities. The results also suggest that efforts to establish general patterns of congruence in ecosystem services and biodiversity may offer a less constructive way forward than do more regional approaches.
