Permafrost on the Tibet Plateau, China

Quaternary Science Reviews, 1995
Abstract The Tibet Plateau represents a unique permafrost environment, being a result of high elevation caused by land uplift in the order of 3000 m over the last 2 million years. Under present climatic conditions, the lower altitudinal limit of permafrost in the north is at ≈4200 m a.s.l., which means that if the Plateau were 1000 m lower than ...

Oblique Stepwise Rise and Growth of the Tibet Plateau

Science, 2001
Two end member models of how the high elevations in Tibet formed are (i) continuous thickening and widespread viscous flow of the crust and mantle of the entire plateau and (ii) time-dependent, localized shear between coherent lithospheric blocks. Recent studies of Cenozoic deformation, magmatism, and seismic structure lend support to the latter. Since

Behavioral mechanisms of male sterilization on plateau pika in the Qinghai-Tibet plateau

Behavioural Processes, 2012
Fertility control is an alternative non-lethal method in the management of rodents. Previous modeling suggests that the efficacy of male sterilization depends on mating systems of animals, but behavioral mechanisms of male sterilization have not been investigated. Here we investigated the behavioral mechanism of the sterilant quinestrol in reducing the

Planation surfaces on the Tibet Plateau, China

Journal of Mountain Science, 2008
A planation hypothesis is proposed to explain landform evolution of the Tibet Plateau. A denudation threshold (T), the maximum potential denudation rate for a certain type of rock, is introduced to explain the combined effects of lithology and tectonics on landform evolution.

The effect of desertification on frozen soil on the Qinghai-Tibet plateau

Science of The Total Environment, 2020
Under the influences of climate change and human activities, desertification has become widespread on the Qinghai-Tibet Plateau (QTP). However, the effect of desertification on frozen soil is still debated. Here, soil temperatures are observed through 14 boreholes at Honglianghe River Basin on the QTP to study the relationship between desertification ...

Carbon Balance in an Alpine Steppe in the Qinghai‐Tibet Plateau

Journal of Integrative Plant Biology, 2009
Abstract Carbon fluxes were measured using a static chamber technique in an alpine steppe in the Qinghai‐Tibet Plateau from July 2000 to July 2001. It was shown that carbon emissions decreased in autumn and increased in spring of the next year, with higher values in growth seasons than in winters.

Pastoral farming on the Qinghai-Tibet Plateau

2018
We report on pastoral farming systems in Henan County (altitude 3600 metres) within the Sanjiangyuan (Three-River Headwaters) Region of the Qinghai-Tibet Plateau. Our information comes from in-depth interviews of 16 pastoral farming families, one focus group, plus discussions with key local informants.

The gravity and isostatic Moho undulations in Qinghai–Tibet plateau

Journal of Geodynamics, 2000
Abstract It is our interest to study the Moho depths in the Qinghai–Tibet. An iterative hybrid spectral–classical methodology is applied to invert the gravity data and obtain the 3D variation in Moho depth. The gravity inversion is constrained by results from deep seismic sounding and seismological investigations.

Microplastics in Qinghai-Tibet Plateau and Yunnan-Guizhou Plateau lakes, China

Science of The Total Environment
As an emerging environmental pollutant, microplastics (MPs) have received widespread attention. Recently, studies examining microplastic pollution in plateau lakes have been increasing, but few have examined the distributions, sources, and fates of MPs in different plateau areas. In this work, the abundances and characteristics of MPs in surface waters
