「海洋」近來受到許多重視，提醒我們以「陸地」之外的觀看視角，重新審視所處的地方。有關宜蘭觀海視域方面的研究極少，本文以傳統詩為研究範圍，鎖定特定文類，進行聚焦討論，凸顯該文類呈現的地方觀看特色，補入臺灣的觀海視域不能缺少蘭陽平原的觀看角度。全文分為「生命之海、生活之海、實境之海、時代之海、抽象之海」五個主題，從文化與歷史的多向詮釋，闡釋蘭陽平原觀看海洋的視域，提供瞭解此地觀海視域的基礎，期待有助於與臺灣其他地區進行後續的比較研究。

＂Ocean＂ has recently received much attention. Treminds us of revisiting the place where we live from another perspective other than ＂Land.＂ As people from diverse cultures, allured by the ocean for whatever reasons, gradually mold their own ocean cultures, there is little poetry research from Ilan's ocean horizon. This paper, focuses on the Ilan's traditional poetry to include Taiwan's poetry research from ocean horizon. This paper is about maritime literature of the Ilan which can be divided into five categories: ＂The Life of Ocean,＂ ＂The Living of Ocean,＂ ＂The Reality of Ocean,＂ ＂An Epoch of Ocean,＂ and ＂The Abstract of Ocean.＂ This paper interports Ilan's traditional poetry from historical and cultural dimensions to provide a better understanding by using an ocean horizon. In addition, this paper could be taken as a base for assisting further comparative studies from other regions of Taiwan.
