身爲宋代的文壇巨擘, 陸遊不僅擅長寫詩作文, 且喜塡詞, 對詞學也有精彩論述。根據他留下的序跋、題記等材料, 可見他較爲豊富的詞學思想。他繼承幷發展了自蘇軾以來詩詞合一的觀點, 對詞的源起、創作、評析以及詞與詩的關係等方面, 均有自己的認識和主張。他的詞學思想是他整體文學思想的一部分, 其中有的看似矛盾之處, 其實幷非眞正的違逆, 相互之間亦有理脈可尋。對詞的認識也深刻影響了他的詞體創作, 他在推尊詞體的同時, 對詞的創作也提出了新的看法和要求。他以作詩的方法塡詞, 從理論和實踐兩方面共同推進了詞的發展。
As Chinese famous writer in Song Dynasty, Lu You was good at writing poems, essays and ci. His thought of ci is also wonderful. According to his text materials, we can find his abundant thoughts of ci. Lu You inherited and developed the view, advocated by Su Shi, that poem and ci was the same in essence. He had his own view of ci`s origin, creation, criticism, as well as the relationship between poem and ci. His idea of ci is a part of his whole literary theory. Sometimes his idea of Ci seemed contradictory, but in fact there is no contradiction, and we can satisfactorily explain this problem now. His recognition of ci deeply affected his ci creation. He not only admired ci but also put forward new opinions and requirements on ci creation. He used a method of poem to write ci. From two aspects of theory and practice, he effectively promoted the development of ci.
