Research And Design On The Plant Landscape Of The Expressway's Road

With the fast development of social economy in our country and people's spiritual and cultural level to further improve, people is no longer satisfied with the transfer of space for traveling, but wish to feel relaxed and happy on the road in the comfortable environment. Therefore, this study research and design for road plant landscape of expressway, hoping to afford the theory and visual reference and the basis for the development and construction of expressway landscape.On the basis of explaining relevant concepts, this study makes the road of expressway divided into middle departing belt, side slope, laterally green belt three parts to carry out the research and design on the plant landscape, combining with visual science, aesthetics, chromatics, ecology and other theories.It points out the function of road plant landscape of expressway is an integrated function, not only the function of the traffic safety but also including green landscaping, retaining solid slope and other integrated functions.Therefore, it focuses on the main functions, landscape types and type characteristics of each part's plant landscape. By the research on the functions and types of each part's plant landscape, and basis on principles and requirements of expressway landscape design, the plant landscape function of each part is separated systemic designed. The mains of each function design are summarized. First is the function design of departing belt's plant landscape. It is mainly design for preventing giddy of the spacing planting and the height of the plant, it puts forward own assumption and analysis for plant design preventing giddy of wider middle departing belt, also expressed own views on sight guiding, and also summed up the conditions of plant choices, it presented a brief analysis of the example. Second is the function design of slope's plant landscape. Except retaining solid slope and landscape design, it mainly analyses the new biotechnology applications for rock slope. Third is the function design of laterally green belt's plant landscape, it mainly design sight guiding and beautiful landscape, and the design for sight guiding is inaugurated. Also it presented a brief analysis of the example.
