英文摘要：

The relevant theory and methods for studying regional crustal deformation with application of GPS technology are reviewed, the modern developments in this field is discussed. The strain analysis with least squares collocation method for displacements and inversion method of negative dislocation model are mainly introduced. The advanced spatial-temporal analysis methods for extraction of crustal deformation signals from space geodetic measurements are prospected.
