李商隱為中、晚唐的代表詩人，其作品中繁複的物象書寫，則能拓展出與宇宙、自然與環境秩序兼及美學的多重對話。本研究以「雪」這個氣候型態，探討李商隱詩的物象書寫與自然感應。首先，就唐代文獻中有關「雪」的敘事，進行主題性考察。在探索史料與詩文後，可以發現雪的災異與美學形象，實為一種對於世界秩序化的訴求；氣候失序影響文明發展的規律，人類則透過對於自然的想像與詮釋，企圖重建秩序的規律以達到和諧的理想境界。參照唐代李商隱與其同時代詩人有關雪的物象書寫，係於此詮釋框架中，所進行的美學再現。本文也將從李商隱詠物詩學中的「春物」與「物華」兩種面向，探究其詩歌中「雪」的存有意涵。

As a representative poet of the mid-to late Tang Dynasty, Lee Shang-yin is renowned for his poetry with complex imageries that bring into dialogue the origin of the universe, natural orders and aesthetics. This research focuses on imageries of snow to analyze Lee's poetic sensitivity to natural phenomena. It begins by reviewing imageries of snow in Tang literature and it induces that the disaster-abnormality of snow and its aestheticized imageries are appeals for order. Since climatic disorder influences the development of civilization, human beings attempt to reconstruct ideal order and harmony by their imaginations and reinterpretations. By cross-referencing poetic works by Lee and by other poets of the era, the research argues that the imageries of snow were represented within this aesthetic framework. The research also discusses the significance of being for snow in Lee's "yon wu" poems, poems on the description of objects, from the aspects of "chun-wu" and "wu-hua."
