摘　　要：青藏高原是全球气候变化的热点区域和敏感区域,高寒灌丛和高寒矮生嵩草(Kobresia humilis)草甸是高寒草甸主要类型,对青藏高原乃至全球的高寒草甸生态系统的可持续发展有着重要的作用。生物量作为反映草地生态系统生产功能的直接指标,是研究其生态系统功能及其他因素之间关系的有效途径。高寒灌丛与高寒矮生嵩草草甸生物量的准确测定和评估是科学认知青藏高原高寒草甸生态功能的关键之一。位于青海省海北州的高寒草地生态系统国家野外科学观测研究站(简称海北站),自2003年和2002年分别开展高寒金露梅(Potentilla fruticosa)灌丛与高寒矮生嵩草生态系统生物量的科学监测,已分别连续积累了17年、18年的原始数据。为准确掌握青藏高原乃至全球高寒灌丛和高寒矮生嵩草草甸生态系统的碳汇潜力及准确预测其生态系统对气候变化的长期响应等相关研究,现公开发表海北通量监测站区2003–2020年高寒灌丛、2002–2020年高寒矮生嵩草草甸相关生物量数据。本数据集包含金露梅灌丛草甸、高寒矮生嵩草草甸地上生物量和地下生物量,可为高寒草甸生态系统生物量时空动态的科学认知、遥感反演、模型验证提供地面观测数据,有助于高寒草甸健康可持续发展。The Qinghai-Tibet Plateau(QTP)is a hotspot and sensitive region affected by global climate change.The alpine shrub and alpine Kobresia humilis meadow are the primary types of alpine meadow found in this area,which play an important role in the sustainable development of the QTP and even the global alpine meadow ecosystem.Biomass,as a direct index reflecting the production function of grassland ecosystem,can be used to effectively study the relationship between grassland ecosystem function and other influencing factors.The precise measurement and assessment of the biomass of the alpine shrub and alpine Kobresia humilis meadow are crucial elements for gaining a scientific understanding of the ecological functions of the alpine meadow on the QTP.The National Field Scientific Observation and Research Station of Alpine Grassland Ecosystem located in Haibei Prefecture,Qinghai Province(Haibei Station)has been conducting scientific monitoring of the biomass of alpine Potentilla fruticosa shrub and alpine Kobresia humilis meadow respectively since 2002 and 2003.Haibei Station has continuously accumulated the original data of these two ecosystems for 17 and 18 years respectively.In order to precisely evaluate the carbon sink potential of the alpine shrub and alpine Kobresia humilis meadow ecosystems in the QTP and even the global,and accurately predict the long-term response of the ecosystem to climate change,we published the biomass data of the alpine shrub(2003-2020)and alpine Kobresia humilis meadow(2002-2020)in the Haibei Flux Monitoring Station.This dataset includes aboveground biomass and underground biomass of the alpine shrub and alpine Kobresia humilis meadow.It can provide ground observation data support for scientific cognition,remote sensing inversion and model verification of the spatial and temporal dynamics of ecosystem biomass in alpine meadows,and contribute to the healthy and sustainable development of alpine meadows.
