Net primary production (NPP) is a fundamental measure of biomass production in ecosystems. In terrestrial biomes, NPP lacks standard measuring protocols and is difficult to measure. Thus, despite decades of research efforts, NPP data are limited and heterogenous. Moreover, there continues to be a lack of global NPP databases containing harmonized estimates for all major ecosystem types and which account for both above- and belowground production. We present a global database containing records for both above- and belowground production for forests, grasslands, arid shrublands, northern peatlands and tundra at 456 sites. The records are reported as annual production (g myr). The NPP data are complemented with detailed site and methodological information, including a method specific estimate for the measurement uncertainty, as well as ancillary data on climatic conditions, soil fertility and management status. This database provides a basis for comparative studies on local, regional and global scales, and may serve as an important benchmarking dataset for the development of DGVMs.
净初级生产力（NPP）是生态系统中生物量生产的一项基本衡量指标。在陆地生物群落中，NPP缺乏标准的测量方案且难以测量。因此，尽管经过了数十年的研究努力，NPP数据仍然有限且参差不齐。此外，仍然缺乏一个全球NPP数据库，该数据库包含所有主要生态系统类型的统一估算值，并且涵盖地上和地下生产。我们展示了一个全球数据库，其中包含456个站点的森林、草原、干旱灌木丛、北方泥炭地和苔原的地上和地下生产记录。这些记录以年生产量（克/平方米·年）报告。NPP数据辅以详细的站点和方法信息，包括针对测量不确定性的特定方法估算值，以及有关气候条件、土壤肥力和管理状况的辅助数据。该数据库为地方、区域和全球尺度的比较研究提供了基础，并可作为动态全球植被模型（DGVMs）开发的重要基准数据集。
