Plant communities are composed of species that differ both in functional traits and evolutionary histories. As species' functional traits partly result from their individual evolutionary history, we expect the functional diversity of communities to increase with increasing phylogenetic diversity. This expectation has only been tested at local scales and generally for specific growth forms or specific habitat types, for example, grasslands. Here we compare standardized effect sizes for functional and phylogenetic diversity among 1,781,836 vegetation plots using the global sPlot database. In contrast to expectations, we find functional diversity and phylogenetic diversity to be only weakly and negatively correlated, implying a decoupling between these two facets of diversity. While phylogenetic diversity is higher in forests and reflects recent climatic conditions (1981 to 2010), functional diversity tends to reflect recent and past climatic conditions (21,000 years ago). The independent nature of functional and phylogenetic diversity makes it crucial to consider both aspects of diversity when analysing ecosystem functioning and prioritizing conservation efforts.
植物群落由功能性状和进化历史都不同的物种组成。由于物种的功能性状部分源于其个体进化历史，我们预计群落的功能多样性会随着系统发育多样性的增加而增加。这一预期仅在局部尺度上针对特定生长形式或特定栖息地类型（如草原）进行过测试。在这里，我们使用全球sPlot数据库比较了1781836个植被样地中功能多样性和系统发育多样性的标准化效应大小。与预期相反，我们发现功能多样性和系统发育多样性之间仅存在微弱的负相关，这意味着这两个多样性方面之间存在脱钩。虽然森林中的系统发育多样性更高，反映了近期气候条件（1981年至2010年），但功能多样性倾向于反映近期和过去的气候条件（21000年前）。功能多样性和系统发育多样性的独立性使得在分析生态系统功能和确定保护工作优先级时，同时考虑这两个多样性方面至关重要。
