High-frequency continuous GPS observation can effectively monitor the kinematics of crustal deformation. The Qilian Mountains region is an important constraint boundary of the northeastern margin of the Qinghai-Tibet Plateau. The study of this region can provide important implications for the dynamic process of the growth and uplift of the Tibetan Plateau and the internal deformation of the Tibetan Plateau. At the local level, it can be discussed whether there is creepage in the Haiyuan fault and the movement mode of the northeastern margin of the Qinghai-Tibet Plateau. The data comes from 26 fixed stations set up by the research group in the Qilian Mountain area. The site selection requirements are strict, and the high-frequency continuous GPS receiver is Provided by trimble, the data quality is good, the data can be applied not only to geodynamic research, but also to related earth science research such as meteorological precipitation.
Under the background of global warming, over the past few decades the qinghai-tibet plateau lakes shows obvious extension. At present on the qinghai-tibet plateau lakes area increase sharply , such as water level changes reported by a number of studies, especially in Tibet's largest lakes such as Siling Co, Nam Co, and so on. We take the Nam Co lake as an example, discussed recent decades the non-structural loading force caused by the Nam Co water level rising result in the surrounding lithosphere deformation and the stress variation on the Yadong-Gulu fault zone (normal fault) and analysis of the seismic hazard. In this fragile ecological environment area, the relationship between the land surface processes and the lithosphere can give us some clues, the result of the data including the surface displacement field changes and the stress on the fault.
