Plant biodiversity is often correlated with ecosystem functioning in terrestrial ecosystems. However, we know little about the relative and combined effects of above- and belowground biodiversity on multiple ecosystem functions (for example, ecosystem multifunctionality, EMF) or how climate might mediate those relationships. Here we tease apart the effects of biotic and abiotic factors, both above- and belowground, on EMF on the Tibetan Plateau, China. We found that a suite of biotic and abiotic variables account for up to 86% of the variation in EMF, with the combined effects of above- and belowground biodiversity accounting for 45% of the variation in EMF. Our results have two important implications: first, including belowground biodiversity in models can improve the ability to explain and predict EMF. Second, regional-scale variation in climate, and perhaps climate change, can determine, or at least modify, the effects of biodiversity on EMF in natural ecosystems.
植物生物多样性通常与陆地生态系统中的生态系统功能相关。然而，我们对地上和地下生物多样性对多种生态系统功能（例如，生态系统多功能性，EMF）的相对和综合影响，或者气候如何调节这些关系知之甚少。在这里，我们梳理了中国青藏高原地上和地下生物和非生物因素对EMF的影响。我们发现，一系列生物和非生物变量占EMF变化的比例高达86%，地上和地下生物多样性的综合影响占EMF变化的45%。我们的研究结果有两个重要意义：第一，在模型中纳入地下生物多样性可以提高解释和预测EMF的能力。第二，气候的区域尺度变化，以及可能的气候变化，可以决定，或至少改变生物多样性对自然生态系统中EMF的影响。
