Constructing the Qinghai-Tibet Railroad: new challenges to Chinese permafrost scientists
نویسندگان
چکیده
The new Qinghai-Tibet railroad will run across the world’s highest permafrost region for 632 km, of which about half is high-temperature and ice-rich permafrost. Therefore, an important and challenging engineering problem is the possible instability and sensitivity of permafrost. Chinese permafrost scientists are now making efforts to solve the problem by carrying out numerous field and laboratory experiments. A GIS-based modeling platform is also being developed. In the paper, we first present the permafrost related problems in the Qinghai-Tibet railroad project, and then introduce some countermeasures for protecting the permafrost.

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....
