Synergistic effect of vegetation and air temperature changes on soil water content in alpine frost meadow soil in the permafrost region of Qinghai-Tibet

Seasonal changes over 2 years (2004–2006) in soil moisture content ( v) of frozen alpine frost meadow soils of the QinghaiTibet plateau permafrost region under three different levels of vegetation cover were investigated. Vegetation cover and air temperature changes had significant effects (synergistic effect) on v and its distribution in the soil profile. During periods of soil freezing or tha...

Surface Deformation Monitoring along Qinghai-tibet Railway Using Small Baseline Sar Interferometry, a Case Study of Beiluhe Section, Qinghai, China

The project of Qinghai-Tibet Railway (QTR) confronts the challenge of surface displacements resulted from seasonal freezing bulge, thawing subsidence and compression settlement. Therefore the embankment instability monitoring is essential for policy makers as well as emergency managers for its operational safety. In this study, we implemented SAR interferometry for extracting ground deformation...

Responses of Soil Microbial Communities to Experimental Warming in Alpine Grasslands on the Qinghai-Tibet Plateau

Global surface temperature is predicted to increase by at least 1.5°C by the end of this century. However, the response of soil microbial communities to global warming is still poorly understood, especially in high-elevation grasslands. We therefore conducted an experiment on three types of alpine grasslands on the Qinghai-Tibet Plateau to study the effect of experimental warming on abundance a...

Information System of the Wetlands on the Qinghai-tibet Plateau

This study establishes an information system of the wetlands and lakes on the Qinghai-Tibet Plateau. We sort up on the wetlands and use Visual Basic 6.0 for the management and development of MapObjects, and the ArcSDE pattern to place the spatial and attribute data into the Microsoft SQL Server relational integrated database. We demonstrate how this Wetland Information System, containing all th...
