Protection of visual resource should be the premise of the rational utilization of scenic spots. In Taihu scenic area, a section of expressway goes across the lake and three ventilation towers should be set up. The landscape coordination between the towers and the surrounding environment is the main research topic of this paper. It was evaluated by landscape sensitivity analysis and landscape visibility analysis. More specifically, the landscape sensitivity is determined by the distance between

... towers and viewpoints, angle relative to the observers' sight line and the probability to be noticed within the main field of vision. In addition, landscape visibility analysis consists of terrain inter-visibility analysis and field-of-view analysis. Finally, after all of these factors have been superimposed, both the directly impacted and the background areas of these towers are used to verify the reliability of this project.
