Permafrost in Northeast China is highly sensitive to climate warming. degradation significantly affects forest and vegetation ecosystems, as well the safety of engineering projects other man-made infrastructures. However, permafrost change region still unclear. This study uses metrological data from 258 weather stations, alongside reanalysis data, environmental investigate its related impacts 1950s 2010s. Results show that total area decreased 4.8 × 105 3.1 km2 The southern limit moved...
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...
Abstract Understanding the long‐term role of cooling underlying permafrost crushed rock structure embankment (CRSE) along Qinghai–Xizang Railway (QXR) is crucial for railway's safe operation. The thermal regime under CRSE analyzed here using monitoring data soil temperature from 2005 to 2015. results show that plays an important in present climate change conditions; however, different types CRSEs have effects. A U‐shaped and a berm with debris revetment can maintain future warming 1.0°C....
ABSTRACT The seasonal freezing layer is an important indicator of frozen ground's responses to climatic warming and environmental changes. In Northeast China, the permafrost taliks interweave with major spatial discontinuity variability. spatiotemporal variability contribution factors these changes are not fully understood. Based on 51 ground temperature monitoring sites in China from 2005 2020, maximum depth (MDSF) was calculated, environment climate‐driven MDSF were analysed by...
Most previous studies of the Qinghai-Tibet engineering corridor (QTEC) have focused on impacts climate change thaw-induced slope failures, whereas few considered freeze-induced failures. Terrestrial laser scanning was used in combination with global navigation satellite systems to monitor three-dimensional surface changes between 2014 and 2015 permafrost QTEC, which experienced two thawing periods a freezing period. Soil temperature moisture sensors were also deployed at 11 depths reveal...
Permafrost is one of the largest elements terrestrial cryosphere and extremely sensitive to climate change. Based on mean annual ground temperature (MAGT) data from 189 boreholes Qinghai–Tibet Plateau (QTP), terrain factors, China Meteorological Forcing Dataset, we propose a new air (MAGAT) statistical model between meteorological parameters with subsurface temperatures simulate permafrost distribution variation MAGT QTP over past three decades (1981–2010). Validation 13 maps indicated that...
Water and heat interact in the process of freezing for saturated soil. And salinized soil, water, heat, salt process, because soil has soluble salt. In this paper, a one‐dimensional mathematical coupled model hydraulic‐thermal‐salt is established. model, Darcy’s law, law conservation energy, mass are applied to derive equations. Consider that column subjected condition moisture migration transport. Both experiment numerical simulation under same developed column. Then content between...
