Abstract. Climate warming and engineering activities have various impacts on the thermal regime of permafrost in alpine ecosystems Qinghai–Tibet Plateau. Using recent observations regimes along highway railway, changes such beneath embankments constructed meadows steppes are studied. The results show that Plateau can a controlling role among construction effects embankments. As before railway construction, artificial table (APT) is not only affected by climate change but also controlled...
Over the years, numerous geotechnical approaches have been implemented to mitigate adverse effects of climate warming on various infrastructures in permafrost region Qinghai–Tibet Plateau (QTP), such as Highway and Railway, achieved expected engineering outcomes. However, little attention has given whether performance these changed during ongoing process warming. To investigate variation one approaches, which is two-phase closed thermosyphon (TPCT), sustained warming, we conducted a...
Abstract An active layer detachment slide (ALDS) in the interior portion of Qinghai–Tibet Plateau (QTP) was investigated within 2 days its formation on September 21, 2018. The ALDS developed a relatively gentle slope (4.8° to 9°) at an elevation 4,850 m above sea level (asl) and about 145 long 45 wide, with headscarp 2.2–2.5 high. Analyses meteorological data soil temperatures indicated that it probably triggered by record thaw depth which intersected high ice content base top permafrost....
Under global warming, permafrost around the world is experiencing degradation which especially so on Third Pole, Qinghai-Tibet Plateau (QTP), China. Retrogressive thaw slump (RTS) one of thermokarst features caused by rapid ice rich permafrost, transforms landforms and threatens infrastructures, even affects terrestrial carbon cycle. In this work, vegetation communities surrounding a RTS in Fenghuoshan Mountains interior portion have been investigated to examine impact from RTS. This...
Aeolian sand significantly affects permafrost degradation, but the effect of aeolian on Qinghai-Tibet Plateau remains unknown. The layer thickness is critical to its role. However, little quantitative research has been conducted In this study, using CoupModel, we investigated differences in impact cover hydrothermal state with 20 different thicknesses (10 ∼ 200 cm, 10 cm increment) and analyzed mechanisms that explain impacts. results reveal active where most permafrost. accumulates...

Using recent observations regimes along Highway Railway, change such beneath embankments constructed meadows steppes are studied. The results show that Plateau can a controlling role within construction effects embankments. artificial table (APT) is predominantly controlled by ecosystems, but rate APT not closely related with those...
