Study On The Freeway Landscape Planning And Design Technology

With the constant development of the society, the changing concept of freeway construction and the request of sustainable development, people not only attach increasingly importance on the freeway landscape problem but also ask for more and more spiritual needs on driving environment. On one hand, freeway landscape is still groping in the early stage lacking of systematic methodological guidance,. On the other hand, facing such large scale and dynamic freeway landscape traditional landscape design theory appear in large limitations. Based on the background, this thesis studies carried out.Using the system analytic method to define the system analytic method, describe the landscape composition and characteristics of freeway, propose the landscape function and the target system, the conformity landscape ecology, the restored ecology, the environmental psychology, the visual theory, the chromatics theory, the landscape esthetics and so on to involve the freeway landscape the theoretical knowledge, summarize the related research theory and the research technique, have determined the corresponding rationale, proposed the landscape plan design overall frame.Landscape planning and design for Freeway basis of the preliminary work is weak, the landscape environment cognition is insufficient, to expand the ponder content, promotes the ponder depth, enhances the plan objective accuracy, has conducted the freeway landscape environment appraisal research. Define the content of the assessment, the value of standards, defined the scope of the assessment, survey methods and content, evaluation index system was constructed to explain the quantitative evaluation index method, applied research combines qualitative analysis and quantitative methods, is proposed based on set on the theory of assessment methods and grading standards, the introduction of the visual landscape and environmental quality and landscape environmental carrying capacity of two indicators were graded landscape environment, a clear view at different levels under the basic strategy of freeway landscape projects and proposed freeway Landscape by paragraph analysis, study area and the division method.In view of the freeway landscape integrant part’s visual sensitive difference, through the vision sensitivity test, has established the landscape district standard and the content. Through the landscape characteristic experiment, has been clear about the freeway landscape plan practice main point, proposed the plan concrete method, the dimension, elaborated the organization procedure which in the plan should use.Combination of landscape design practice and related research results, summarized the freeway landscape planning and design elements commonly used in the basic principles, methods, and points.Application of qualitative analysis and quantitative research methods combined to construct a general impression of the landscape by road, freeway landscape elements, road and surrounding environment, visual quality of the environment for the study of freeway landscape evaluation system, based on set pair analysis theory, the corresponding evaluation methods and evaluation criteria. Project examples show that the method of the system is easy to grasp, easy to operate, has some promotional value.Totally speaking, this paper established a comparatively complete freeway landscape evaluation, planning, designing and evaluation theory for future research and also laid a theoretical foundation for freeway landscape engineering practice providing methods for reference. It has important guiding meaning as well as realistic significance.
