species-specific root biomass per plot per layer in 2012 and 2014

Root biomass was sampled to a depth of 40 cm and separated into five depth layers in the Trait-based biodiversity experiment in Jena, Germany, in 2012 and 2014. This file contains root biomass per species per layer per plot per year. A description of each variable is included on a separate sheet called ‘metadata’ in each file.

2012年及2014年，在德国耶拿开展的基于功能性状的生物多样性实验（Trait-based biodiversity experiment）中，科研人员对深度达40厘米的根系生物量进行了取样，并将其划分为5个深度层。本数据集包含各年份、各样地、各深度层下各物种的根系生物量数据。每个文件中名为"metadata"的独立工作表均收录了各变量的详细说明。
