英文摘要	Drylands are one of the most sensitive areas to anthropogenic climate change and are projected to experience accelerated expansion throughout the end of this century. However, the responses of drylands degradation to anthropogenic ecosystem changes remain unclear. This study proposes a new perspective of the 'oxygen footprint', defined as the ratio between oxygen consumption and oxygen production, which could be regarded as an indicator in evaluating the effects of anthropogenic climate change on global dryland ecosystems. A global distribution of the trend of oxygen footprint in response to climate change indicators and the transformations for ecosystem functioning is presented. The response of oxygen footprint to human activities and global warming is projected to enhance in the 21st century. Under a high emissions scenario (RCP8.5), linear regression analysis between oxygen footprint and other indicators shows oxygen footprint to increase with the increase of air temperature, precipitation, potential evapotranspiration and dryland areas, respectively. Our study suggests that when oxygen production is unsustainable combined with oxygen consumption, this scenario will accelerate the degradation of dryland ecosystem, with fundamental and negative consequences for the capacity of drylands to supply essential ecosystem services.
