藏北样带植被生物量数据（2017年）

植被调查数据是研究生态系统结构与功能必不可少的数据。藏北地区蕴含广袤的草地生态系统，主要包括高寒草甸、高寒草地、以及高寒荒漠化的草地。由于独特的地理位置以及高海拔缺氧的环境条件，在藏北高原的群落调查数据较为稀少。本课题组基于前期工作的积累，在2017年生长季对整个藏北高原15个县域开展了较为全面的植被调查。本数据集包括藏北样带上从那曲到日土县23个采样点的围栏内外的生物量数据。本数据集可用于生产力的空间分析与模型的校准工作。

Vegetation survey data are essential for researching the structure and function of ecosystems. The Northern Tibetan Plateau hosts vast grassland ecosystems, primarily consisting of alpine meadows, alpine grasslands, and alpine desertified grasslands. Owing to its unique geographical location and high-altitude hypoxic environmental conditions, vegetation community survey data from this region are relatively scarce. Based on accumulated prior research, our team conducted comprehensive vegetation surveys across 15 counties of the entire Northern Tibetan Plateau during the 2017 growing season. This dataset includes biomass data from 23 sampling sites along the Northern Tibet transect, extending from Nagqu to Ritu County, covering both inside and outside fenced plots. This dataset can be applied to spatial analysis of productivity and model calibration.
