Desertification and its relationship with permafrost degradation in Qinghai-Xizang (Tibet) plateau
Desertification in Qinghai-Xizang (Tibet) Plateau is part of Chinese desertification. In the past decades, due to the climate warming, the climate condition in Qinghai-Xizang (Tibet) Plateau has been relatively dry. This has resulted in permafrost degradation and other environmental problems. In addition, the vegetation and the soil layer were also destroyed by unreasonable economic activities....
متن کاملInformation 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...
متن کاملEco-environmental effects of the Qinghai-Tibet Plateau uplift during the Quaternary in China
L. Fengquan 7 B. Jianmin College of Environment and Construction Engineering Changchun University of Science and Technology, Changchun City. 130026. P.R. China Abstract The Qinghai–Tibet Plateau uplifted 13000 m in the Quaternary period. The average rate of uplift was 1–1.1 mm/year. The uplifting has remolded the geomorphology of China. The landform in China was changed from west-low and east-h...
متن کاملResponses of Permafrost on the Qinghai-Tibet Plateau, China, to Climate Change and Engineering Construction
Monitoring of permafrost along the Qinghai-Tibet (Xizang) Highway shows that there is a large difference in the response of permafrost to climate change and to engineering construction. The change in cold (,21.5uC) permafrost is greater than that in warm ($21.5uC) permafrost under the effect of climate change, while the cold permafrost is less sensitive to the disturbances from engineering acti...
متن کاملGroup size effect on vigilance: evidence from Tibetan gazelle in Upper Buha River, Qinghai-Tibet Plateau.
Tibetan gazelle Procapra picticaudata is a threatened and endemic species to the Qinghai-Tibet Plateau. With the method of group scan sampling, we observed the behaviours of males and females of the gazelle in the two summers of 2005 and 2006, in order to test the group size effect on group vigilance. We found that male gazelles were significantly more vigilant than the females at both group sc...
