| description | Abstract The Tibetan Plateau’s unique geography has attracted significant research interest in near-surface atmospheric oxygen concentration. Understanding the impacts of elevation, temperature, and precipitation on oxygen concentration patterns in various bare lands is essential for enhancing resilience against hypoxia and promoting sustainable development in high elevation regions. This paper utilized near-surface oxygen content data and systematic field sampling data from the Tibetan Plateau to examine the spatial distribution of oxygen concentration in dry and ice-snow melting bare lands, along with its relationships with altitude, temperature, and precipitation. The results showed the following: (1) In dry bare land, the annual average oxygen concentration ranged from 19.93 to 20.24%, with values of 19.84–20.10% in January and 20.03–20.40% in July. In ice-snow melting bare land, oxygen levels were lower, with an annual range of 19.71–20.11%, and monthly values of 19.61–20.01% in January and 19.82–20.29% in July. (2) A significant negative correlation existed between elevation and oxygen concentration, every 1000 m increase in elevation reduced the dry and ice-snow melting bare lands by 0.133% and 0.134%, respectively. Conversely, temperature correlated positively with oxygen concentration, within the same area, every 10 °C rise in temperature increased the dry and ice-snow melting bare lands by 0.166% and 0.163%, respectively. Also, precipitation negatively impacted oxygen concentration in dry land but showed no significant effect in ice-snow melting bare land. (3) Elevation and temperature were the primary factors influencing oxygen concentration in both land types, while precipitation had a more limited effect. This research enhanced the understanding of the mechanisms governing near-surface oxygen concentration in the Tibetan Plateau’s bare lands, providing a scientific basis for addressing hypoxic conditions in the region. |
