The project measures plant biomass at the landscape scale and relates it to above- and belowground plant traits for analysing leaf, wood and root economics spectra using the EFForTS trait database. Root competition in the Oil Palm Biodiversity Enrichment Experiment is analysed with a mechanistic approach. In addition, the existing multi-year record of productivity data in the EFForTS plots is extended to a 10-yr time series of NPP and NEP with the aim to analyse inter-annual productivity fluctuation in dependence on climate variation and system diversity and complexity.

该项目在景观尺度上测量植物生物量，并将其与地上和地下植物特征联系起来，以便使用EFForTS特征数据库分析叶、木材和根经济谱。用机理方法分析了油棕生物多样性富集试验中的根系竞争。此外，EFForTS地块生产力数据的现有多年记录扩展到10年的NPP和NEP时间序列，旨在分析年际生产力波动依赖于气候变化和系统多样性和复杂性。
