俗曲自明代宣德、正統年間興起後，就盛行不輟，直迄清末民初才走入衰微，也留傳下大量的曲詞文獻。檢視這些文獻，可以發現其中存有許多類同及翻轉的曲詞，可見仿擬及翻案應為俗曲重要的運用手法。本文即在探查仿擬與翻案手法在俗曲中的運用，除分析這些手法的類型及運用內容外，並探討其形成原因，也藉此瞭解了仿擬及翻案手法的運用，能讓曲詞不斷大量繁衍，實為俗曲長久盛行不輟的重要功臣。

Su Qu have been wildly prevailing since their beginning in Ming Dynasty, and they were not until the late Ching Dynasty and the early Republic of China that they began to decline. While examining the abundant references of Su Qu, it can be found that there seems to have many similarities and correlations between the lyrics and songs. Thus, it can be asserted that imitation and variation are crucial techniques of Su Qu. This research aims to probe into the ways of imitation and variation by analyzing the different types they used with and songs they used in. Furthermore, by discussing the reasons behind these approaches, one can begin to understand the multiplied lyrics and songs of Su Qu and the profound impact on the progress and development of Su Qu.
