To measure and monitor the crustal motion in China, a GPS network has been
established with an average side length of 1 000 km and with more than 20 p
oints on the margins of each major tectonic block and fault zone in China.
Three campaigns were carried out in 1992,1994 and 1996, respectively by thi
s network. Here we present, for the first time, the horizontal displacement
rates of 22 GPS monitoring stations distributed over the whole China and g
lobal IGS stations surrounding China, based on these GPS repeated measureme
nts. From these results by GPS, we have obtained the sketch of crustal moti
on in China.
