魏晋南北朝是军旅诗创作的转折期,也是诗歌理论的总结期,《昭明文选》(以下简称《文选》)诗列出“军戎”类即其显著标志。军旅诗虽跻身众多诗歌门类之列,但从所选军旅诗人与诗作的数量来看,军旅诗并未获得主流诗歌类别的地位。《文选》中与《文选》以外不乏军旅题材的诗作,其未能入选大致有以下的原因:一是《文选》贯穿始终的辨体意识;二是当时对军旅诗的理解较狭隘,相应地缩小了它的外延;三是整个时代诗歌潮流的影响。此外,对诗题的标志性、题材的纯粹性、手法的纪实性等方面的追求亦为“军戎”类诗入选的隐形条件。 The Wei, Jin and the Southern and Northern Dynasties are the turning point of military poetry writing and the concluding period of the theory of poetry. The poems of “Zhao Ming Anthology” (hereinafter referred to as “Wenxuan”) list the “military” category. Although military poetry among the many categories of poetry, but the number of military poets and poems selected from the point of view, military poem did not get the mainstream poetry category status. There are many poetic writings about military subjects outside the “Wenxuan” and “Wenxuan”. The reason for their failure to be enrolled is as follows: First, “anthology” runs through the consistent awareness of discrimination; secondly, the understanding of military poetry at the time is rather narrow. Accordingly, Narrowed its extension; Third, the trend of poetry throughout the era of influence. In addition, the pursuit of poetry’s landmark, pure subject matter, documentary technique and other aspects is also the invisible condition for the selection of “military”.
