Divergent runoff impacts of permafrost and seasonally frozen ground at a large river basin of Tibetan Plateau during 1960–2019

open access: yesEnvironmental Research Letters, 2022
Since the 20th century, due to global warming, permafrost areas have undergone significant changes. The degradation of permafrost has complicated water cycle processes.

Role of permafrost degradation on evapotranspiration on the Qinghai-Tibet Plateau

open access: yesShui kexue jinzhan, 2022
The Qinghai-Tibet Plateau (QTP), known as the "Asian Water Tower", is extremely sensitive to climate change. Studying the impacts of permafrost degradation on evapotranspiration is conducive to improving the understanding of the response of hydrological ...

Observed permafrost thawing and disappearance near the altitudinal limit of permafrost in the Qilian Mountains

open access: yesAdvances in Climate Change Research, 2022
Permafrost degradation has been widely reported on the Tibetan Plateau (TP). However, directly observed evidence of permafrost thawing processes and degradation rates are very limited, although it is expected to be prevalent near the periphery of a ...

Impacts of degrading permafrost on streamflow in the source area of Yellow River on the Qinghai-Tibet Plateau, China

open access: yesAdvances in Climate Change Research, 2019
Many observations in and model simulations for northern basins have confirmed an increased streamflow from degrading permafrost, while the streamflow has declined in the source area of the Yellow River (SAYR, above the Tanag hydrological station) on the ...

Experimental and Numerical Analyses of the Thermal Regime of a Traditional Embankment in Permafrost Regions

open access: yesAdvances in Materials Science and Engineering, 2021
Traditional embankment is widely used in the permafrost regions along the Qinghai-Tibet Railway (QTR) because of its simple construction and lower cost. However, this form of embankment has insufficient ability to resist external thermal disturbance.

Impacts of Permafrost Degradation on Carbon Stocks and Emissions under a Warming Climate: A Review

open access: yesAtmosphere, 2021
A huge amount of carbon (C) is stored in permafrost regions. Climate warming and permafrost degradation induce gradual and abrupt carbon emissions into both the atmosphere and hydrosphere.

Modeling Wildfire-Induced Permafrost Deformation in an Alaskan Boreal Forest Using InSAR Observations

open access: yesRemote Sensing, 2018
The discontinuous permafrost zone is one of the world’s most sensitive areas to climate change. Alaskan boreal forest is underlain by discontinuous permafrost, and wildfires are one of the most influential agents negatively impacting the condition of ...

Soil Enzyme Activities and Their Relationships With Soil C, N, and P in Peatlands From Different Types of Permafrost Regions, Northeast China

open access: yesFrontiers in Environmental Science, 2021
Peatland is a key component of terrestrial ecosystems in permafrost regions and have important effects on climate warming. Soil enzymes are involved in biogeochemical cycle of soil carbon (C), nitrogen (N) and phosphorus (P), which can be used as early ...

Permafrost‒vegetation controls on water availability over the Qinghai‒Tibet Plateau

open access: yesAdvances in Climate Change Research
Permafrost degradation substantially affects water resources within the cryosphere. It is crucial to elucidate the dynamics of water availability influenced by both permafrost degradation and climate change to fully comprehend the water cycle in cold ...
