太空歌剧一直以来都较为缺乏研究者的关注。新浪潮时期科幻文学的创作一定程度由关注科技的“硬科幻”向关注社会人文的“软科幻”进行了转变，而太空歌剧的创作也发生了较大的变化，思想厚度与创作水准都得到了极大的提升。《沙丘》作为这一时期太空歌剧的代表作品，蕴含着作者弗兰克·赫伯特丰富的关于政治、社会、生态等多维度的哲思。本文从《沙丘》的文本与情节出发，从宗教思考、反战思想、超自然能力与生态观念四个方面对作者的观念与主张进行剖析。

Space opera has long received less attention from researchers. In the New Wave period, the creation of science fiction literature has changed from "hard science fiction" focusing on science and technology to "soft science fiction" focusing on society and humanity to a certain extent, while the creation of space opera has also undergone great changes, and the ideological thickness and creative level have been greatly improved. Dune, as a representative work of space opera in this period, contains Frank Herbert's rich philosophy on politics, society, ecology and other dimensions. Starting from the text and plot of Dune, this paper analyzes the author's ideas and propositions from four aspects: religious thinking, anti-war thought, supernatural ability and ecological concept.
