摘　　要：地球参考框架是地球坐标系统的实现,本文系统介绍了地球参考框架的确定方法,结合ITRF2005参考框架,详细介绍了地球参考框架联合解算的方法,并对地球参考框架的质量分析方法进行了探讨。One of the foundations of the application and research of earth science is to establish long-term stability and high accuracy of terrestrial reference frame. Terrestrial reference frame is calculated using a variety of space technologies by IERS, to mee the needs of baseline measurement in a period of time. In this paper, the process and characteristics of using a variety of space technologies （GPS, SLR, VLBI） to determine terrestrial, reference frames were respectively introduced. A conventional combination methodology and a new one which is at the observational level were synthetically introduced. Several methods of analyzing the qualities of terrestrial reference frame were summarized.
