Problem statement: Modern semiotics has opened new avenues for research in various fields of science, and it has expanded the process of analysis in different branches by providing models. It seems that semiotics can provide a framework for landscape architects.
Research objective: This research seeks to discover the relationship between semiotics and landscape architecture to develop a framework for the analysis and design of landscape architecture based on semiotics.
Research method: This article employs the comparative method to analogize a landscape to a text and semiotics to a text analysis tool. Using a descriptive-analytical method, it examines and analyzes the basic concepts, opinions, and divisions of experts in the field of semiotics and proposes combined models for analysis and design.
Conclusion: Preparing a mixed three-dimensional model, which studies thephysical, semantic and audience-based dimensions of the landscape in relation to each other for landscape studies, based on the Peirce and Hjelmslev models, is one of the findings of the study. It has also applied Wang’s extended model of Hjelmslev in studies of physical and Meaning dimensions. It is a three-step pattern for finding the meaning of a landscape or giving it meaning.
