青藏高原地上生物量数据集（2021-2023）

青藏高原是我国草地生态系统的重要组成部分，约占全国草地面积的 1/3 ，在气候调节、水源涵养和维系生态平衡中至关重要。青藏高原积累了大量的有机碳，地上生物量是土壤有机碳的重要来源，是反映草原生态系统、放牧系统稳定性的重要指标，其大小可判断草原状况、草地生产潜力和草地载畜能力等。基于此，我们在2021-2023年间对青藏高原进行了地上生物量的调查，收集了青海省和西藏自治区共计49个样点，单位为（g·m-2）。

The Qinghai-Tibet Plateau is a critical component of China's grassland ecosystems, accounting for approximately one-third of the country's total grassland area, and plays a vital role in climate regulation, water conservation and maintaining ecological balance. The Qinghai-Tibet Plateau accumulates substantial amounts of organic carbon. Aboveground biomass, an important source of soil organic carbon, serves as a key indicator reflecting the stability of grassland ecosystems and grazing systems; its magnitude can be used to evaluate grassland conditions, grassland production potential and livestock carrying capacity, among other metrics. Against this background, we conducted a survey of aboveground biomass across the Qinghai-Tibet Plateau between 2021 and 2023, collecting a total of 49 sampling sites from Qinghai Province and the Tibet Autonomous Region, with the unit being g·m⁻².
