Study On Regional Characteristic Landscape Design Of Chengde-Chifeng Expressway

With the development of expressway in our country,the function of expressway is not only satisfied with smooth traffic,the environmental effect and landscape effect are also paid more and more attention in the process of construction.To create a good road landscape needs to combine the landscape resources,the representative geographical elements such as ecological environment and cultural characteristics should be added to landscape design.So the highway landscape not only has the regional characteristics but also has a higher visual experience,it provides a good driving environment for drivers.In this paper,I adopt these design patterns of prophase planning,overall layout and detailed planning and these methods of questionnaire investigation,data analysis and data summary to get the importance ranking of regional cultural elements.The region of Chengde-Chifeng expressway is divided into four landscape segments according to geographical features and cultural characteristics.So,Highway landscape built on each landscape section can reflect the landscape features of the section.According to landscape design theory,I design the landscape of side slope,service area,toll gate,viewing platform and tunnel portal based on architectural style of Qing Dynasty,the culture of Manchu and Mongolian and Ecological characteristics and so on.This design method for highway landscape design has played a good role model.This paper uses the method of AHP and fuzzy comprehensive evaluation to evaluate the tunnel entrance landscape.The evaluation result is good,so the tunnel portal landscape to create a good effect.
