唐代士大夫、僧人所寫的與佛教寺院相關詩作，數量龐大，占《全唐詩》所收詩作的十分之一強，而且唐代的文士也存在游寺、宿寺的習尚，深入剖析這些游居寺院的作品，除了有助於瞭解唐代長安的社會生活及文化特性之外，更可以從另一個側面，觀察唐代詩歌風格的演變。嚴耕望曾提及唐代存在著長安文化區的特性，本文針對長安寺院相關詩作，包含長安附近的終南山區，一併觀察，提出唐代長安佛寺詩歌寫作風格有著對於寫景由實質走向空明、對於佛理由名相走向禪悟、對於語言從精緻走向口語的三個特質，希冀從另一個側面，觀察唐代詩歌風格的演變。

The number of poems about or related to Buddhist monastery by Tang literati or monks is amazingly large, occupying more than one-tenth of the whole corpus of Tang Poetry. In addition, it was common custom that the Tang literati was frequently visiting or living in Buddhist temples. The analysis of the poetry written on or about Buddhist temples therefore can not only help us to understand the social life and cultural atmosphere of the time, but also help us to further observe the development of different writing styles of Tang poetry. As eminent scholar Yen Keng-wang once remarked that there existed a so-called Changan cultural area, this article attempts to look into the poetry related to Buddhist monastery surrounding Changan neighborhood, including Mountain Chungnan, and posits the idea that the monastery poetry of Changan has three characteristics: from realistic to philosophical in scenery description; from appearance to ecstasy in realization of the Buddhist style; from deliberate to easy and oral in language. The author hopes, in the final analysis, to offer an observation of the transformation of styles in Tang poetry through the study of the monastery poems of Changan.
