Abstract: In the field of landscape architecture, the main difficulty in the basic design teaching is the transformation from concept to form. The development of conceptual design is often directed by topological thinking in an architecture or landscape project. Based on the place theory of the existential space and the architectural space of Christian Norberg-Schulz, this paper puts forward the method of “topological composition”. This method is based on the integration of various spatial scales, with the abstract “point-line-plane” as the basic element, thereby studying the topological relations of the functional elements, in order to produce a spatial composition, then fit it to a specific site and transform it into a landscape form with the real scale.
