Research Of Highway Landscape Design

With the rapid development of expressways in China, Highway has gradually become the connection between city traffic artery, and Play an increasingly important role in national economic construction.In recent years, along with the people ecology environmental consciousness’ s enhancement and esthetic ability’s enhancement, as well as walked the sustainable development path’s request, the harmony between expressway and landscape along the route brought to people’s attention gradually. How to enable the expressway construction both meet people’s journey needs, and can harmonize with the environment, this is the new problem which expressway construction faced. In developed countries have a specially designed mature mechanism, however, the expressway landscape design in China is still in the stage of exploration and development.This study regard this as the starting point,by referring to a great dealof literature knowledge,design philosophy,design method and expertise, profound essentials and methods of highway landscape,we have put forward some rather views and have formed a comprehensive theoretical system. On the basis of the research, impression shaping and emotional expression of achieved way. Finally, through the Guangxi-jingna Highway landscape design in practice theory, hoping for Highway entrance landscape design provides a theoretical basis, came to the following conclusion:1. Highway landscape design with plant landscaping design as the main line,to meet functional requirements(such as glare, inducing sight) at the same time, to create a beautiful landscape along the route, and strive to build "green ecological corridor security, fast, comfortable, harmonious".2 Highway greening structure system is a dynamic three-dimensional space landscape, with linear green(rope) and green(node) in two forms, namely, the typical "knot" landscape. The highway landscape design mainly includes the main greening(rope) and tunnel import and export, interchange and service area green(node) two parts.3. Highway landscape design to ensure the smooth and safe running of the road foundation and premise, linear green design is focused on "potential", that is, to highway slope, green belt, smooth and continuous natural visual effect is good, be consistent coordination and environment landscape elements; and the green design is focused on "shape" in the selection of plants for greening, and the other, the main scenic spots of the architectural style, the identification of place, but the memory of that elements of landscape design methods of treatment.4. Design of linear structure, along the highway, should as far as possible to avoid mistake cut the ecological environment of space or visual landscape space, should be coordinated with the local customs and practices, local history and culture, showing the charm of local culture and. At the same time must be designed to maintain long-term natural economic benefits, try to avoid the destruction of the natural environment and the original landscape, protection of animals and plants and places of historic interest and scenic beauty.5. In the direction of the theory, the completion of the Guangxi Jingxi to Napo expressway greening design. In the design to achieve "suit one’s measures to local conditions, suitable tree"; landscape coordination, focusing characteristics, to highlight the cultural characteristics of the local ethnic minorities, which has obvious geographical characteristics and landscape identification.
