Abstract: Based on the premise of landscape space structural and deconstructionism, the theory of pattern language was developed with a basic logic thinking way to understand the total landscape space, which integrated with varies space icon at different scales, from small space to large space and from parts to total landscape space under the inner process of coupling horizontally and nested vertically and spatial relations. The landscape space icons are basic units for landscape components and structure, process and function, perception and its images. Landscape space can be recognized, understood, inherited, shaped and created under the spatial reasoning of landscape space forming process, which is a reversible process that landscape space can be deconstructed to learn and structuring to shape. Base on the logical thinking way of landscape, the theory promoted the concept model, the systematical framework and its inner logical relations existing in the system and the mechanism of locality and universality of pattern language. Practice research has proved that landscape pattern language helps to realize the method and theory of local landscape inheritance and innovation, to promote the personalization and characterization of perception in the process of landscape space shaping, it explores a new way to effectively study and design landscape.
