客家籍現代詩文知名作家葉日松先生，其詩歌創作歷程超過五十年，不僅數量甚夥，關懷層面亦廣。他所創作的三行詩，相對其他詩作，在形式與風格上有不小的差異性。三行詩或可稱為短詩，其篇幅相對短小，在載體有限的狀態下，如何清楚表達情感或主題意象，對創作者而言是極大的考驗，也具有相當大的挑戰性。回溯現代詩歌的發展，五四時期是小詩創作的黃金年代，諸如俞平伯、朱自清、冰心等人都寫出許多獨創性極強的小詩，內容簡單，卻非常精彩。本論文探究葉日松先生三行詩對傳統的繼承狀況外，亦關心藉由不同詩體開拓自己書寫的深度與廣度，透過探討其短詩的美學意涵，進而觀察作家詩歌藝術層面的多元風貌與積極創新的創作能量

Mr. Yeh, Jih-Sung, a well-known writer of modern Hakka poetry, has been devoted to the writing of poetry for more than fifty years. So far, he has created a numerous number of poems, which covers lots of aspects. The three-line poem he created has a distinct difference in form and style when compared with other poems.

By exploring the aesthetics meaning of his short poems, we can observe the diverse artistic style of the writers and creative energy of innovation
