2019年青藏高原植被调查数据

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。青藏高原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。本数据集包括2019年藏北样带上47个采样点的的地上生物量和盖度数据，采样时间为7-8月。样方大小为50cm×50cm，烘干后称取植物干重。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 indispensable for studying the structure and function of ecosystems. The Qinghai-Tibet Plateau hosts vast grassland ecosystems, mainly including alpine meadows, alpine grasslands, and alpine desertified grasslands. Due to its unique geographical location and hypoxic environmental conditions at high altitudes, community survey data for the Northern Tibetan Plateau are relatively scarce. This dataset contains aboveground biomass and coverage data from 47 sampling sites along the transect in the Northern Tibetan Plateau in 2019, with the sampling period being July to August. The quadrat size was 50 cm × 50 cm, and plant dry weight was measured after drying. This dataset can be used for spatial analysis of productivity and model calibration.
