Ecological Landscape Evaluation Of Nanyou Expressway In Guangxi

Highway is a big project,human nature is attached to the large banded structures on the surface of the earth,the traditional highway only to meet the traffic demand of human beings,ignore the ecological,cultural and aesthetic connotation,however,as people increasingly pressing need for a better life,past monotonous roads need to transportation,ecology,culture and tourism as one of the scenic byway.As an extremely important route connecting ASEAN countries,Nanyou Expressway has been open to traffic for 13 years.It has far-reaching practical significance to explore and study its ecological landscape.In this paper,on the basis of learning from previous research results,combined with the actual situation of the highway to analyze and compare a variety of landscape evaluation methods,determine the use of POE as the basic research basis;In addition,the AHP-fuzzy mathematical method was used to comprehensively evaluate the ecological landscape of Nanyou expressway,and the entropy weight model of the evaluation system was constructed based on the principle of entropy,so as to improve its scientificity and objectivity.The main research contents and results are as follows:1.This paper discusses the related research trends and progress,and summarizes the trend of gradually digitizing,publicizing and perceiving the expressway landscape research.The use of post-evaluation belongs to the category of landscape evaluation of psychophysical school.Through the discussion,comparison and reasoning of various landscape evaluation methods,it can be seen that the use of post-evaluation method in highway landscape evaluation is scientific,reasonable,practical and feasible.2.It is proposed that the three elements of highway landscape perception are:sense of landscape,sense of environment and sense of security.The three criteria of the evaluation system from the user’s perspective are landscape effect,ecological environment quality and safety design.Based on the characteristics of zonal,dynamic,multi-dimensional and multi-dimensional characteristics of highway landscape,15 selected highway landscape perception index factors are analyzed in detail.3.Using entropy method,the entropy weight model of ecological landscape evaluation of Nanyou expressway is constructed,and the entropy weight of the criterion layer in the evaluation system is 0.243 for landscape effect evaluation,0.277 for ecological environment quality evaluation,and 0.480 for safety design evaluation respectively.After handing out questionnaires to highway users and collecting and calculating,it is concluded that the comprehensive evaluation score of ecological landscape of Nanyou expressway is 3.95,and the overall evaluation grade is good.4.Combined with field research status summary to potential highway landscape characteristics and the regional background analysis of the various factors of the highway landscape evaluation of different population diversity and needs,targeted optimization Suggestions,such as light green,strengthen the natural show,appropriate to add winter flower plants,the use of additional leisure facilities,strengthening the borrow scene technique,improving cultural display,integrated into the landscape,new ideas and build distinct themes such as"music"of the highway.In this paper,from the Angle of the social public Nanyou highway ecological landscape analysis and study of system science,build the Nanyou scenic byway of compound function for the future lay the foundation,and is the"big data"and"artificial intelligence"the new stage of the highway landscape construction needs,hope for the future to build a new concept of highway landscape to provide reference for the construction of the scientific basis and research.
