Research on the Construction Method of Landscape Information Model Based on GIS

With the development of information technology, computer digital technology is widely used in the process of landscape design. GIS technology provides powerful help in landscape planning and design, and expands the creative generation way through qualitative and quantitative integrated environment. In this paper, the construction method of landscape information model is studied from the perspective of landscape design, and the process and functional characteristics of landscape information model construction are proposed. The basic framework of landscape information model is constructed through sustainable theory, graphic theory and decision theory, GIS technology is adopted, and visual interaction platform is used to improve the landscape information model, and multiple sensory elements are combined to carry out landscape experience. Finally, the landscape information model can reproduce the environment, simulate and predict the process, and provide more scientific and reliable guidance for landscape design.
