中晚唐七律向齐梁宫体诗的功能扩张

Functional expansion of the seven-character regulated verses in the middle and late periods of the Tang dynasty to the aulic-styled verses of the Qi-Liang dynasties

七律与五律在形式、来源、起源时代等方面各不相同,早期七律在功能上与以齐梁宫体诗为代表的早期五律也有很大差异,但在元和以后,七律已承担起了早期五律的主要功能,包括赋题、咏物、体写女色等。中晚唐七律兴起的艳情诗风可视为七律的功能向宫体诗方向扩张的结果。与此同时,这些功能在五律中却呈现出萎缩的倾向。这种现象表明,在不同源的文体之间,后起文体可以承担起固有文体的功能。

Seven-character regulated verses differ from five-character regulated verses in their forms,sources,and historical periods. In terms of function,the early seven-character regulated verses were quite different from the early five-character regulated verses represented by the aulic-styled verses of the Qi – Liang dynasties. However,after the popularity of Yuanhe poetry,seven-character regulated verses had the functions of the early five-character regulated verses like theme-based writing,description or praise of things and beauty. The erotic style of the seven-character regulated verses in the middle and late periods of the Tang dynasty was a result of its functional expansion to the aulic-styled verses of the Qi – Liang dynasties. At the same time,these functions showed atrophy in the contemporary five-character regulated verses. This phenomenon reveals that a new style can functionally inherit the old one,although their origins are different.
