In recent years, with the growing concern on the antiphony of Tang dynasty, researchs began to pay attention to joint sentences poem. To my point of view, the reason of low achievement of poem-joint sentences is the insufficience of further study and the limitation of reserch range, particularly the joint sentence poem of Tang Dynasty lacks further reserch and integrate reserch system. So I determined to make the joint sentences poem of Tang Dynasty ( the 1st year of Gaozu Wude-the 4th year of Xuandi Tianyou ,year 618–year 907) to be the study subject of my thesis.

近年来随着对唐代唱和诗越来越多的关注，研究者们也开始留意唱和诗中一种特殊的形式——联句诗，但笔者所见之文章多因联句诗总体创作成就不高的原因，或笔墨过于节省，或泛泛而谈、不够深入，或者囿于点的探讨和积累，对联句诗特别是联句诗发展黄金期的唐代尚缺乏进一步详细地整理和系统研究，这一现状使我确定了以唐代(高祖武德元年618年——宣帝天佑四年907年)联句诗为本文的研究对象。
