2015-2020年若尔盖高寒草甸碳水热通量观测数据集

A dataset of carbon,water and heat fluxes of Zoige alpine meadow from 2015 to 2020

高寒草甸由于其巨大的碳储量和广泛的分布,是青藏高原最重要的生态系统之一。了解高寒草甸生态系统中的碳通量对于理解和预测高寒地区碳储存的动态至关重要。本数据集为若尔盖(红原)高寒草甸生态系统2015–2020年通量观测数据,数据采集地位于青藏高原东缘的红原县高寒草甸生态系统野外科学观测研究站,基于开路式涡度相关系统,同时观测了二氧化碳通量、甲烷通量以及水热通量。本站数据通过中国通量观测研究网络(ChinaFLUX)数据处理体系形成了一套长期连续标准化的生态系统碳水通量和关键气象要素数据集。本数据集对准确评价青藏高原高寒草甸生态系统碳水通量在区域和全球碳水循环中的地位和作用具有重要意义。

With abundant and widespread carbon,Alpine meadow boasts one of the most important ecosystems on Qinghai-Tibet Platea.It is essential to observe the carbon,water and heat fluxes in alpine meadow ecosystem for understanding and predicting the dynamics of carbon storage in alpine regions.This dataset includes the observation data of carbon,water and heat fluxes in Zoige alpine meadow from 2015 to 2020.The data collection work was carried out at the Field Scientific Observation and Research Station of Hongyuan alpine meadow ecosystem on the eastern edge of the Qinghai-Tibet Plateau.Based on the open-circuit vorticity correlation system,the observation work also covers the carbon dioxide flux,methane flux,water and heat flux.The data of this station has been sorted out a set of long-term,continuous and standardized datasets of ecosystem carbon and water fluxes and key meteorological elements through the data processing system of China Flux Observation and Research Network(ChinaFLUX).This dataset is of great significance for accurately evaluating the position and role of carbon and water fluxes in the regional and global carbon and water cycles of the alpine meadow ecosystem in the Qinghai-Tibet Plateau.
