“贞观体”最早由晚清台湾诗评家吴德功提出,但吴氏没有阐明“贞观体”的内涵,因而这个概念一直未引起学界重视。本文考察发现,贞观诗歌以应制诗、咏物诗为主要载体,形式精美、风格典雅,具有大体一致的外在风貌。它采用相对稳定的“三部式”结构,还有着目的性极强的现实功用。更重要的是,贞观末期诗歌的各种要素逐渐同质化,形成了比较一致的体貌、体式和体格。因此,本文认为,“贞观体”的概念是成立的。 “Zhen Guan body ” was first proposed by Wu Dekong, a poet in Taiwan in the late Qing Dynasty, but Wu did not clarify the connotation of “Zhen Guan body ”. Therefore, this concept has not drawn academic attention all along. In this study, we find that Zheng Guan’s poems take the composing poems and chanting poems as the main carriers, which are beautiful in form and elegant in style, and have a generally consistent external appearance. It uses a relatively stable “three ” structure, there is a very purposeful practical function. More importantly, the various elements of the late Zhenguan period poetry gradually homogenized, forming a more consistent physical appearance, body style and physique. Therefore, this article argues that the concept of “Zhen Guan body ” is established.
