許慎的《說文解字》是中國語言學史上的經典之作，然而是書經歷代傳抄摹寫面目已非漢代之舊。因此，自“二徐”以來多有校讎。清代“小學”昌盛，恢復許書原貌即是《說文》學家們的第一要務。從20世紀初到新中國成立前，有關《說文》校訂的成果較少。新中國成立以後，随着的學術繁榮，相關成果日漸趨多，成就顯著。不過，以往的成果在資料運用的廣度和考訂的廣度方面都存有提升的空間。 本文即在前人研究的基礎上，搜集更多的《說文》校勘資料，進行綜合考訂，以期在一定程度上恢復《說文》的本來面目。目前，本研究的考訂部分已經完成，這裏呈現的約占全部內容的八分之一。 第一章爲緒論，簡要介紹了選題的緣起、已有研究綜述、研究的意義與價值、研究的方案、研究進展與研究報告框架。第二章爲《說文》正文校訂，主要運用歷代《說文》異文校訂大徐本《說文》，這裏只選取了大徐本有明顯訛誤的492例。第三章以《慧琳音義》徵引《說文》爲例，揭示了古籍徵引《說文》的方式及其用字情況。第四章以《慧琳音義》徵引《說文》爲例，闡述了運用徵引異文從事《說文》校訂應該注意的問題。結語部分簡要歸納了大徐本《說文》存在的文獻錯誤，申述了掌握古籍徵引《說文》的方式與用字情況對於《說文》校勘的意義以及應該注意的問題。

Xu Shen's Shuowen Jiezi is a classic work in the history of Chinese linguistics. However, it is not its original look in Han Dynasty that the book has been copied and copied from generation to generation. Therefore, since ErXu there have been many collations. The linguistics and philology of the Qing Dynasty was flourishing and the restoration of its original appearance were the first priorities scholars of Shuowen.

At present, the textual research part of this study has been completed, which represents about one eighth of the total content. The first chapter is the introduction, which briefly introduces the origin of the topic, the research summary, the significance and value of the research, the research program, the research progress and the Research Report framework. Chapter two is the textual research of Shuowen, which mainly uses yiwen of Shuowen from previous dynasties to revise Daxu's Shuowen, which only selected 492 cases of obvious errors in Daxu's Shuowen. Chapter three takes Shuowen cited in Huilin Yinyi as an example to reveal the way in which Shuowen was cited in ancient books and the use of its characters.
