摘　　要：文章阐述了建立天球参考系的传统方法和已作出的贡献,介绍了射电天体测量和空间天体测量的前景及其存在的不足之处,认为继续发展高精度的地面基本天体测量仍然是必要的。In this paper, the transitional methods to construct a celestial reference system are discussed, and the advantages and the disadvantages of radio astrometry and space astrometry are also described. Based on the above discussions, we come to the conclusion that the ground-based astrometry is still and will be necessary.
