紀行賦在兩漢煟然勃興並卓成一體，不僅呈露在作品數量上，更體現於諸凡主題內容、體裁結構、遣詞用典、精神風貌等諸多文體表徵，這些共同構成了賦在紀行文學中的書寫機制（convention），以致後世賦家推尚模範不輟。本文旨在對起自《詩經》，迄至西漢末劉歆（ca.53B.C.-23A.D.）之〈遂初賦〉的這一段被之千載的紀行賦誕生全景進行全盤回顧，進而爬羅剔抉作為紀行賦生發源頭的《詩經》、《楚辭》及漢初騷賦中涉及行旅的篇章，斠證最早期的述行紀錄對紀行賦雛形初態的塑成影響，最終揭橥〈遂初賦〉在主題、結構、語言、程式上對紀行賦乃至整個紀行文學形成的樹幟意義。

The rise of poetic travelogues in the rhapsody (fu) during the Han dynasty is not only reflected in the quantity, but in the establishment of convention which is comprised of topics, contents, structures, techniques and styles. This convention had been constantly followed and enriched by later generations. My article attempts to comprehensively examine the evolution of poetic travelogues through tracing the major source of convention served as a prelude of Liu Xin (c.50BC-AD23)'s ＂Fu on Fulfilling My Original Resolve＂ back to the earliest Classics, such as the Book of Songs the Songs of Chu and other earlier literary writings on journeys. Light is shed on the interrelationship between these earliest pieces of works and the mature of poetic travelogues in the Han fu. Last but not least, I address the literary features of Liu Xin's works and conclude that it play an inspiration role in the formation of convention of this specific genre of fu.
