Abstract: Classical gardens, as a kind of medium language for transferring information, can realize the information exchange between people. Taking the concept of linguistics as the theoretical basis, applying Morris’s theory of linguistic semiotics to the classical garden translation system, the classical garden design language was divided into three parts, namely, "pragmatics" "semantics" and "syntax", and the use of classical Chinese garden translation techniques in modern public display areas was analyzed from the perspective of language, and the embedded paths of spatial translation techniques, image translation techniques, formal translation techniques and emotional translation techniques were analyzed in detail from the aspects of spatial layout, garden images and gardening emotions, so as to make clear the design process, and to establish the complete classical garden design language translation system. On this basis, the empirical study of the translation system was carried out in combination with actual cases, obtaining high-quality design results, so as to provide a reference for the landscape design of modern public display areas.
