Greening Design And Engineering Of Tourism Highway On The North Slope Of Qinling Mountains

With the rapid development of social economy and the implement of the scientific development view, peopleliving standard continuously raise, and the tourism is booming, people have more high-level demands for the cultural life and living environment. Good highway landscape would pleasure pedestrian psychosomatic, improve traffic fluency, and also promoted the benign development of local economy. It is still a new subject of road builders that how to show the scenery along the way and improve the traffic environment, and realize the harmony of human and nature based on the greatly original ecological environment protection..The tourism highway in the northern slope of Qinling Mountains was taken as the research object in this paper. Based on the principal of landscape ecology and with the guidance of highway landscape theory, ecology, aesthetics etc, the comprehensive analysis of highway landscape was selected, and the related concepts and theories of mountains tourism highway landscape design was introduced. Main results are as follows:(1) both sides of highway should be widen, and Coronilla?varia and Trifolium?repens ware planted as subgrade buffer; the green belts in the two side of the highway will be replace with the forest of Koelreuteria paniculata, Populus tomentosa, Ligustrum compactum and Prunus cerasifera f. atropurpurea;(2) Ligustrum quihoui whit 40 cm high was designed as the main tree species of hedge, and Prunus ? cistena and Ligustrum ? vicaryi whit 60 cm high ware planted at?a?distance?of 50 meter;(3) eight nodes park ware constructed in transportation hub. Design scheme was used to guide the construction, in order to promote the development of highway landscape design theory, the safety of traffic, the quality of travel environment, the rapid development of local tourism economy, and the harmonious development of man and nature.
