摘要：《步天歌》属初唐作品，主要记载两汉时期以后的星象。由于其主要靠抄本流传，且行文过简，枝节缺失较多，讹误差错不少。但《步天歌》是对隋唐之际传统的三家星官混一的歌诀式总结，流传甚广。朝鲜、日本、越南及邻近我国东南沿海国家都有其流传。因此，《步天歌》无疑是一部具有较大影响的古代天文星象诗歌著作。%Bu Tian Ge (The Heaven- footing Song) is a book mainly describing the appearances and changes of the stars during the two Han Dynasties. It has been handed down in the form of hand - written copies and now few of them can be found. It is too briefly written, with many missing words and quite a few pen errors. In spite of all these, it is qualified enough to be called a poem - type summary about the traditional constellation descriptions between the Tang and Sui Dynasty,and has been spread as far as to korea,Japen,Vietnam and some other nearby eontries. Bu Tian Ge is no doubt a greatly influential poem style ancient academic work about consellation and astronomy.
