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.

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.

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

Effects of grassland degradation on ecological stoichiometry of soil ecosystems on the Qinghai-Tibet Plateau.

Science of the Total Environment, 2020
Grasslands across the world are being degraded due to the impacts of overgrazing and climate change. However, the influences of grassland degradation on carbon (C), nitrogen (N), and phosphorus (P) dynamics and stoichiometry in soil ecosystems are not ...

Active layer thickness calculation over the Qinghai–Tibet Plateau

Cold Regions Science and Technology, 2009
Abstract The rising air temperature and increased human activities have caused permafrost degradation over the Qinghai–Tibet Plateau, including thickening of the active layer. The active layer plays an important role in cold regions. Active layer thickness (hereafter ALT) variation may have profound socio-economic and eco-environmental consequences ...

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.

Xanthone glycosides in Gentianceae of Qinghai-Tibet plateau

1999
Abstract Most species of Gentianaceae in Qinghai-Tibet Plateau are traditional Tibetan medicines which were used for stabilizing liver functions and improving the gallbladder. They were used for curing hepatitis, cholecystitis and other diseases.
