摘　　要：定义了综合权并利用最小二乘法建立起满足Tisserand条件的区域参考基准,并对"中国地壳运动观测网络"1999—2004年基准站、基本站和中国大陆周边的7个IGS站速度场进行分析,初步建立了中国大陆及其周边地区的构造环境图像。Crustal movement analysis based on GNSS velocity field has become a powerful means to research geosciences problems,among which,determining the regional reference for tectonic environment analysis of China continent and its surrounding areas is very necessary.This paper defines the regional reference by using the least square method with the comprehensive power that satisfies the Tisserand condition.With reference stations and basic stations of the＂Crustal movement observation network of China＂（1999-2004）and 7IGS stations around China mainland,we analyze velocity field and initially establish the tectonic environment image of China mainland and its surrounding areas.
