Abstract：Crustal movement analysis based on GNSS velocity field has become a powerful means to re-search geosciences problems,among which,determining the regional reference for tectonic environment a-nalysis of China continent and its surrounding areas is very necessary.This paper defines the regional ref-erence by using the least square method with the comprehensive power that satisfies the Tisserand condi-tion.With reference stations and basic stations of the"Crustal movement observation network of China"(1999-2004) and 7 IGS stations around China mainland,we analyze velocity field and initially establish the tectonic environment image of China mainland and its surrounding areas.
