自注是作者用以为自己作品作说明备注的内容，是作品的副文本，在诗歌这类文体中并不受重视。唐代是诗歌自注开始发展、完善的时期，而有关此时期诗歌自注的研较少，对唐诗自注的探讨，或许能够补充推动唐诗的整体研究。据统计，白居易是中唐时期自注诗歌最多的诗人。其自注内容丰富，保有大量的文献内容，在治史，补遗诗人诗作、时俗文化等方面有很高的价值。而对白居易诗集中自注的研究却仍不够深入。故而本研究会以《白居易诗集校注》中的自注为研究对象，首先，对其中的自注作全面的统计梳理工作，从前人未曾关注的宏观角度观察自注的内容及分布情况。研究将自注内容分作三类：（一）背景注，（二）体式注，（三）音注。从自注的分布情况中发现，白居易对不同诗体、不同诗歌内容及不同诗句位置的注文有其各自的作用。其次，研究基于谢思炜《白居易诗集校注》，参照朱金城《白居易诗集》，对照金泽本及那波本，对白居易诗歌现有自注进行辨疑，补充前人研究之不足。在金泽本及那波本的自注内容的研究中，两个本子呈现出不一样的内容保存倾向，这对诗歌自注的研究方向有一定拓展。最后，研究发现自注与白居易之创作研究关系密切。并从文学传播与接受、声律观念、创作理念三个方面，深入探究自注在其中的作用。总之，本研究发现白居易诗集中的自注并非白氏一时兴起之作，而是在反复的创作及编集过程中深思熟虑的结果，其中深刻反映出了白氏的创作初衷。

Self-annotations are a type of literary genre that authors use to provide additional explanations and reference to their works. They are a secondary text in literary works, and there are not given much attention in the field of poetry. The Tang Dynasty is a period which self-annotations began to develop and perfect themselves, but there were few studies on the self-annotations of poetry in this period. The discussion on self-annotations on Tang poetry may be able to supplement and promote the overall research on Tang poetry. According to statistics, Bai Ju Yi is the poet who wrote the most self-annotations in the middle Tang Dynasty. His self-annotations are rich in content and contains a large amount of literature content, which is of high value in the study of history, addendums to poet’s poems, and culture of the Times. However, research on Bai’s self-annotations is always on the periphery and there is no in-depth discussion. Therefore, this research took the self-annotations of Bai Ju Yi’s Poems as the research object.Firstly, the study conducted a comprehensive statistical analysis of the self-annotations, and observed the content and distribution of the self-annotations from a macro perspective that has not been paid attention to before. The self-annotations content is divided into three categories: (1) background annotations, (2) style annotations, and (3) phonetic annotations. From the distribution of self-annotations, the study found that Bai has his own effects on different poetic styles, different poetic contents and different positions. Secondly, based on the editions of Bai’s Poetry works by Xie Si Wei, referring to Zhu Jin Cheng’s Bai Ju Yi’s Poetry Collection, and comparing the Kanazawa version and Nabo version, the research identified doubts about the existing self-annotations of Bai’s poetry, and complemented the shortcoming of previous studies. In Kanazawa version’s and Nabo version’s self-annotations studies, these two versions showed different contents preservation tendencies, which expands the research direction of poetry’s self-annotations to a certain extent. Finally, this study discovered that self-annotations were closely related to Bai’s creative process. From three aspects of (1) literary dissemination and acceptance, (2) poetic concept, and (3) creative philosophy, this study deeply explored the role of self-annotations in Bai’s works.Overall, the study found that Bai’s self-annotations are not a random production, but rather a result of careful consideration and writing during the repeated process of creation and complication. They reflect Bal’s original intention in creating the poems.
