Studies On Xi’an Freeway Interchange Landscape Construction

At present, with the rapid development of domestic highway construction, the national economic development is promoted vigorously,at the same time, people’s daily travel efficiency is improved. However, the highway as a large man-made structures,which has brought adverse effects on the natural ecosystems along the highway.For this reason, more and more people are concerned about it’s greening landscape construction work, in order to create a green landscape to mitigate the adverse impact of highway construction on the natural environment. In view of this,the article selects the important node of motorway- interchange as a starting point, at the same time,the article is based on the landscape aesthetic theory, in order to search the problems of domestic greening landscape construction work after comparing with the United States, Japan and Germany in the aspects of the landscape construction situation,in order to fully draw on the successful foreign experience,then,the article takes the actual case of Xie’wang Interchange and Chang’an Interchange for example,so as to obtain the design principles,landscape design goals and specific methods that should be mastered, in order to provide highly valuable comments and suggestions for the practical landscape design work of domestic highway interchange their landscape,so as to enhance the quality of highway Landscape design. The researchresults are as follows:(1) at the beginning of the future of China’s highway construction, landscape planning work should be carried out in advance, combined with the natural ecological environment area of the highway, landscape planning and design to make a detailed plan to make eco freeway green areas and roads which Environmental mutual harmony.(2) In the highway interchange landscape design should adhere to the principles of integrity, aesthetic principle, the principle of regional security principles in order to create and interchange surrounding the overall ecological environment in harmony with Interchange where the area’s unique geographical and cultural characteristics, and to ensure the safe passage of vehicles, and bring beauty interchange landscape experience for passengers.(3) When the highway interchange landscape construction, landscape and should ensure that transport interchange capabilities to adapt, combined with the natural elements of good, traffic space increasingly clear and convenience, with better visual continuity as a design goal.(4) According to the freeway interchange location, can be divided into freeway overpass in a natural area, located within the city and highway interchange located in the city entrances or transport interchanges highway interchange three categories, and each Interchange species should be taken in harmony with the surrounding environment to create a method of green landscape.(5) In view of highway interchange landscape quality is not high status, before future interchange construction project began, landscape designers and other staff should be involved in the interchanges along the construction process, in order to enhance national highway interchange Landscape Construction level.
