目的植被样地记录提供关于在同一群落中共存的植物的存在和覆盖或丰度的信息。植被图数据分散在研究小组、环境机构和生物多样性研究中心，因此很少能在大陆或全球范围内获得。在这里，我们提出的sPlot数据库，整理全球植被图，允许在植物群落水平的分类，功能和系统发育多样性的全球模式的探索。sPlot 2.1版包含来自1，121，244个植被样地的记录，其中包括1885年至2015年期间在全球范围内收集的23，586，216个植物物种及其相对覆盖或丰度的记录。我们通过检索气候和土壤条件以及地理环境（例如，生物群）从外部来源，并通过计算社区加权平均数和方差的性状使用的缺口填补数据从全球植物性状数据库TRY。此外，我们为图中确定的54，519个物种中的50，167个创建了系统发育树。我们提出了第一张社区丰富度和社区加权关键性状的全球模式图。结论sPlot中植被样地数据的可用性为全球范围内的植被分析提供了新的途径。
Aims Vegetation-plot records provide information on the presence and cover or abundance of plants co-occurring in the same community. Vegetation-plot data are spread across research groups, environmental agencies and biodiversity research centers and, thus, are rarely accessible at continental or global scales. Here we present the sPlot database, which collates vegetation plots worldwide to allow for the exploration of global patterns in taxonomic, functional and phylogenetic diversity at the plant community level. Results sPlot version 2.1 contains records from 1,121,244 vegetation plots, which comprise 23,586,216 records of plant species and their relative cover or abundance in plots collected worldwide between 1885 and 2015. We complemented the information for each plot by retrieving climate and soil conditions and the biogeographic context (e.g., biomes) from external sources, and by calculating community-weighted means and variances of traits using gap-filled data from the global plant trait database TRY. Moreover, we created a phylogenetic tree for 50,167 out of the 54,519 species identified in the plots. We present the first maps of global patterns of community richness and community-weighted means of key traits. Conclusions The availability of vegetation plot data in sPlot offers new avenues for vegetation analysis at the global scale.
