[1] In this paper we summarize recent research in geocryological studies carried out on the Qinghai-Tibet Plateau that show responses of permafrost to climate change and their environmental implications. Long-term temperature measurements indicate that the lower altitudinal limit of permafrost has moved up by 25 m in the north during the last 30 years and between 50 and 80 m in the south over the last 20 years. Furthermore, the thickness of the active layer has increased by 0.15 to 0.50 m and…

Changing climate and the permafrost environment on the Qinghai–Tibet (Xizang) plateau
Permafrost on the Qinghai–Tibet Plateau (QTP) has undergone degradation as a result of recent climate change. This may alter the thermo‐hydrological processes and unlock soil organic carbon, and
Permafrost dynamic change on the Tibetan Plateau under climatic warming since 1950s
The Tibetan Plateau is situated in one of Earth’s extreme continental climate settings and is influenced by numerous climatic regimes such as the East Asian and Indian monsoons and westerlies. It is
Effects of Permafrost Degradation on Soil Hydrological Processes in Alpine Steppe on the Qinghai-Tibet Plateau
Abstract Permafrost degradation is prevalent on the Qinghai-Tibet Plateau. This may lead to changes in water and heat transition in soils and thus affect the structure and function of ecosystems. In
Response of the soil hydrothermal process to difference underlying conditions in the Beiluhe permafrost region
The changes in hydrothermal dynamics under different underlying conditions are the important aspect of hydrological and ecological processes, and engineering stability in permafrost regions. This
Thermal state of permafrost and active layer in Central Asia during the international polar year
Permafrost in Central Asian is present in the Qinghai–Tibet Plateau in China, the Tien Shan Mountain regions in China, Kazakhstan and Kyrgyzstan, the Pamirs in Tajikistan, and in Mongolia. Monitoring
Recent ground surface warming and its effects on permafrost on the central Qinghai‐Tibet Plateau
In this study, the ground surface temperature (GST) records from 16 meteorological stations, which are located in or adjacent to permafrost regions on the central Qinghai‐Tibet Plateau (QTP), are
Changes in active layer thickness over the Qinghai‐Tibetan Plateau from 1995 to 2007
[1] The active layer over permafrost plays a significant role in surface energy balance, hydrologic cycle, carbon fluxes, ecosystem, and landscape processes and on the human infrastructure in cold


With climatic warming, significant changes are occurring in the permafrost regions in China. On the QinghaiXizang Plateau, the southern limit of permafrost has been degrading at a rate of hundreds of
Accelerated thawing of subarctic peatland permafrost over the last 50 years
In this study we provide a quantification of the main patterns of change of a subarctic peatland caused by permafrost decay monitored between 1957 and 2003. Up‐thrusting of the peatland surface due
Prediction of permafrost distribution on the Qinghai-Tibet Plateau in the next 50 and 100 years
Intergovernmental Panel on Climate Change (IPCC) in 2001 reported that the Earth air temperature would rise by 1.4–5.8°C and 2.5°C on average by the year 2100. China regional climate model results
Permafrost and Changing Climate: The Russian Perspective
Results from mathematical modeling indicate that by the mid-21st century, near-surface permafrost in the Northern Hemisphere may shrink by 15%–30%, leading to complete thawing of the frozen ground in the upper few meters, while elsewhere the depth of seasonal thawed ground may increase on average by 15%"–25%, and by 50% or more in the northernmost locations.

Over 550 km roadbed of the Qinghai-Tibetan Railway is constructed in permafrost Regions. Analyzing the data of main observatories on permafrost regions in the Tibetan Plateau, it is found that the
Thermal regimes and degradation modes of permafrost along the Qinghai-Tibet Highway
Permafrost on the Qinghai-Tibet Plateau (QTP) is widespread, thin, and thermally unstable. Under a warming climate during the past few decades, it has been degrading extensively with generally rising
Impact of the anomalous thawing in the Tibetan Plateau on summer precipitation in China and its mechanism
The impact of the anomalous thawing of frozen soil in the late spring on the summer precipitation in China and its possible mechanism are analyzed in the context of the frozen soil thawing date data
Interaction between Permafrost and Desertification on the Qinghai-Tibet Plateau
The observed data of ground temperature and ground surface heat balance were used to analyze the interaction between permafrost and desertification on the Qinghai-Tibet plateau. The results showed
Historical Overview of Permafrost Studies in China
Although soil freeze/thaw phenomena were reported centuries ago in the historical Chinese literature, systematic study of permafrost in China started in the 1950s. Permafrost research in China has
