The GPS study of the crustal movement and deformation at Qinghai-Xizang plateau" is a key project of the state Natural Sciences Fund in the Eighth Five-Year Plan,Its aim is to establish a high precison GPS observation net and cooperate with the geological and geophysical disciplines, develop the study of the crustal movement and deformation of the Qinghai-Xizang plateau and earth dynamics.

The space measurement and control stations are distributed in the different plates all over the world,and the site coordinates must be changed according to crust deformation.

It is shown that Dali area will be one of the most hazard zone of earthquake of Yunnan Province in the future ten years, based on the analyses of tendency variation of precursor factors of geomagnetic, gravity fields, crust deformation and ground water in the area for many years.

According to our research in the southern Tibet, based on the summary and analysis of researching results domestics and overseas, this thesis systematically study the problem of crust deformation of south Tibetan Plateau with geology tectonic, deformation model, GPS data process and forward and inversion of crust deformation.

Characteristics of present-day crustal deformation and seismicity in western China;

Floating velocity calculation in GPS crustal deformation monitoring;

The crustal deformation and the coseismic displacement were measured during the 7.
