河北沽源站1997-2005年生物监测数据

本数据产品是在《中国生态系统定位观测与研究数据集》丛书的《草地与荒漠生态系统卷系统卷》之河北沽源站1册的基础上进行数字化加工，通过完善元数据并与实体数据相关联，生产了本数据产品。本数据集为河北沽源站生物监测数据，包含放牧对地上生物量和新麦草繁殖特性的影响、放牧对草地植物重要值变化的影响、放牧对植物补偿生长的影响。数据范围自1997年至2005年。本数据产品同时包含沽源观测点介绍及观测指标获取方法与过程的关联文档。

This data product was produced via digitized processing based on Volume 1: Hebei Guyuan Station of the Grassland and Desert Ecosystem Volume from the series *China Ecosystem Fixed Observation and Research Datasets*, by improving the metadata and linking it with physical entity data. This dataset contains biological monitoring data from Hebei Guyuan Station, covering three core research topics: the effects of grazing on aboveground biomass and the reproductive characteristics of Psathyrostachys juncea, the effects of grazing on changes in the importance value of grassland plant communities, and the effects of grazing on plant compensatory growth. The data spans from 1997 to 2005. Additionally, this data product also includes supporting documents that introduce the Guyuan observation station and detail the acquisition methods and processes of the monitoring indicators.
