Abstract: In landscape planning and design, visual relationship has always been an important content of analytical research. In a mountainous or hilly environment with complex terrains, tools such as GIS can help planners make better decisions. At present, GIS, a geographic analyzing tool, has been widely applied to the visibility analysis of various industries. However, in the field of landscape architecture planning, especially linear spatial planning, GIS view analysis methods and considerations are still relatively single. This paper takes G247, a tourist highway in the city of Zigong as an example, introducing various evaluation parameters such as cumulative field of view and visual amplitude. Based on the ArcGIS and ENVI platforms, coupled with GIS tools, python programming and remote sensing image supervised classification and interpretation, this research adopts three levels including surface type, visibility of terrain and spatial characteristics are used to study the road landscape evaluation and control methods in typical mountainous and hilly areas in Southwest China. It provides methods for expanding and improving the application of the GIS technology in linear visual relationship evaluation planning.
