青藏高原地表大气含氧量（1980-2019）

基于1980-2019年青藏高原及附近105个气象站点的气象数据（数据源于中国气象局数据国家气象科学数据中心）计算含氧量，发现含氧量和海拔显著线性相关，y=-0.0263x+283.8,R2=0.9819。因此基于DEM数据栅格计算得到含氧量分布图。由于青藏高原地区自然环境的限制，相关定点观察机构较少，本数据可在一定程度上反应青藏高原地区含氧量的分布情况，对青藏高原人类生存环境等相关研究有一定的借鉴意义。

Oxygen content was calculated based on meteorological data from 105 meteorological stations on and around the Qinghai-Tibet Plateau during 1980–2019, which were sourced from the National Meteorological Science Data Center, China Meteorological Administration. A significant linear correlation was found between oxygen content and altitude, with the regression equation y = -0.0263x + 283.8 and R² = 0.9819. Thus, the oxygen content distribution map was generated by raster calculation based on DEM data. Due to the limitation of the natural environment in the Qinghai-Tibet Plateau, there are few relevant fixed-point observation institutions. This dataset can reflect the distribution of oxygen content in the Qinghai-Tibet Plateau to a certain extent, and provides certain reference significance for relevant studies such as those on the human living environment of the Qinghai-Tibet Plateau.
