This paper introduces some results in measuring crustal deformation of some key parts where crustal movement is violent and strong earthquake happened in China by using D-InSAR technology, and analyses the pregnant procedure of crustal deformation resulted by strong earthquake, and study the relationship between crustal deformation of strong earthquake and active tectonic, and imitate the stress background, and research the distribution law of China crustal movement and strong pregnant environment. By above research, some good process methods of D-InSAR are defined, especially, some area deformation quantity is less can be measured by D- InSAR.
