Study On The Application Of Landscape Planning Of Tourism Highway In Qiannan Mountainous Area

With the development of economy and the improvement of people’s living standards,the role of transportation in tourism is becoming more and more obvious,and transportation+tourism is also getting more and more attention from the industry.At present,there is no industry standard system related to tourism highway landscape technology in China.In this paper,on the basis of in-depth study of tourism highway landscape theory,based on the accessibility of tourism resources,optimize the layout of highway network,study the landscape planning technology of tourism highway in Qiannan mountain area,provide reference for the construction of tourism highway.Firstly,this paper analyzes the theoretical system of tourism highway landscape,and studies the main points of tourism highway landscape design,the theory of optimal traffic flow dynamic scale design,the theory of driving speed dynamic scale design,the theory of landscape visual sense dynamic scale design,and the theory of tourism highway landscape coordination evaluation are analyzed,it provides the scientific and theoretical basis for the research of the key technologies of the project landscape.Secondly,Using the optimization model of tourism resources accessibility road network,investigating the regional traffic data,forecasting the tourism traffic volume,optimizing the grade of Qiannan tourism highway,scientifically determining the optimized layout and construction standard scale of Qiannan astronomical tourism highway road network,and making the greatest efforts to activate the regional tourism resources.Secondly,The paper studies the overall planning and design scheme of tourism highway landscape in the mountainous area of South Guizhou Province,and puts forward the overall idea,design theme and design structure of tourism road landscape design.This paper makes an in-depth study on the route design of tourist highway,puts forward the key points of route selection and the technical requirements of horizontal and vertical alignment indexes,studies the subgrade and pavement technology of tourist highway,and puts forward the subgrade cross-section layout style and pavement structure material technical indexes.The key points of ecological protection technology for subgrade slope are studied.The planning of slow greenway,the optimization scheme of Greenway pavement section and the experience of Greenway culture are studied.Finally,This paper focuses on the landscape planning and design of ancillary facilities of tourism highway,studies the layout requirements of tourism service facilities,and puts forward the planning points of highway tourism service center,highway viewing platform and rural characteristic experience.This paper studies the construction requirements of tourism safety protection facilities,and puts forward the key technologies of planning and design,such as the key points of speed limit design,the style of safety guardrail,and the technical specifications of greening and environmental protection.Through the study of this paper,we can get the following conclusions:first,the landscape design of tourism highway highlights the characteristics,the theme is bright,and pays attention to experience and road landscape integration.Second,the design of tourism highway is based on the accessibility of resources,scientifically optimize the road network layout,and dynamically design the grade standard.Third,the tourism highway landscape design should carry out targeted dynamic design from the aspects of route design,subgrade and pavement,fast forward roaming system,tourism service facilities,safety and environmental protection,so as to create landscape exciting points.The research results and project practice of this paper can provide some reference for the construction of tourism highway in other parts of the country,and have positive significance for promoting the development of tourism in Qiannan Prefecture and promoting the integration of "transportation+tourism".
