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.

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.

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.

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

A Study on the Detection of Deformation of Tuotuohe Area on the Qinghai-Tibet Plateau

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
In permafrost regions, the ground surface deformation is closely related to the ice-water phase transition process in active layer and underground ice. It is of great significance to carry out ground surface deformation detection research for understanding the development of permafrost in the Qinghai- Tibet Plateau. The InSAR technology has been proved

Vertical distribution of Pu in forest soil in Qinghai-Tibet Plateau

Journal of Environmental Radioactivity, 2021
The 239+240Pu and 137Cs activities and 240Pu/239Pu atom ratios in surface soil and soil core collected from Qinghai-Tibet Plateau were investigated. The maximum of 239+240Pu and 137Cs activity concentrations in five soil cores were found in upper layers and have a same trend: the maximum followed by exponential decline.

The Electrical Structure of Northeastern Qinghai-Tibet Plateau

Chinese Journal of Geophysics, 2005
The electrical conductivity model of the crust beneath northeastern Qinghai-Tibet is obtained from inverting TE and TM mode responses simultaneously using the non-linear conjugate gradient inversion (NLCG) algorithm. The result shows that there exist high electrical conductivity layers in the middle and lower crust beneath the northeastern Qinghai ...
