Aboveground and belowground species interactions drive ecosystem properties at the local scale, but it is unclear how these relationships scale-up to regional and global scales. Here, we discuss our current knowledge of aboveground and belowground diversity links from a global to a local scale. Global diversity peaks towards the Equator for large, aboveground organisms, but not for small (mainly belowground) organisms, suggesting that there are size-related biodiversity gradients in global aboveground-belowground linkages. The generalization of aboveground-belowground diversity relationships, and their role in ecosystem functioning, requires surveys at scales that are relevant to the organisms and ecosystem properties. Habitat sizes and diversity gradients can differ significantly between aboveground and belowground organisms and between ecosystems. These gradients in biodiversity and plant community trait perception need to be acknowledged when studying aboveground-belowground biodiversity linkages.
地上和地下物种相互作用在局部尺度上驱动着生态系统属性，但尚不清楚这些关系如何扩展到区域和全球尺度。在此，我们讨论从全球到局部尺度上关于地上和地下多样性联系的现有知识。对于大型地上生物而言，全球多样性在赤道附近达到峰值，但小型（主要是地下）生物并非如此，这表明在全球地上 - 地下联系中存在与体型相关的生物多样性梯度。地上 - 地下多样性关系的概括及其在生态系统功能中的作用，需要在与生物和生态系统属性相关的尺度上进行调查。地上和地下生物之间以及生态系统之间，栖息地大小和多样性梯度可能存在显著差异。在研究地上 - 地下生物多样性联系时，需要认识到生物多样性和植物群落特征认知方面的这些梯度。
