| In 2016,with the formulation of the guidelines for Greenway Planning and design by the Ministry of housing,the construction process of ecological infrastructure and greenway was speeded up nationwide.Relying on its own natural resources,the advantages of the cultural landscape and the strong support of the capital,Beijing has already laid the green road of nearly 800 kilometers in recent years,and most of the green road has been put into use.Nowadays,greenway is increasingly becoming an important place for people to touch the natural environment,and its design rationality has become particularly important.How to better promote the improvement of the built green road through the user’s post use evaluation and to provide reference experience for the future construction of green road has become an important problem to be solved in the green road construction.In view of this,this paper takes the green road in the downtown area of Beijing as the research object,constructs a comprehensive evaluation model of the green road in the central city of Beijing,analyzes the main factors that affect the green road comprehensive environmental assessment and puts forward the optimization strategy,in order to provide some reference for the design and modification of the green road in the central city of Beijing.The paper is divided into three parts and five chapters.The first part is basic research,including first,second chapters.This paper expounds the background of the research,and collate the history,types and methods of the development of correlation theory.At the same time,the research object and content of the study are clarified,and the research framework of the thesis is combed out.The second part is the case study,including third,fourth chapters.The author made a field survey on the green road in Beijing central city,and finally selected the greenway of the five mountains,the greenway of the ring second ring and the greenway in Chaoyang Park as an example,and carried out the qualitative and quantitative research respectively.First of all,we use behavior map,questionnaire,interview and other methods to carry out qualitative analysis,to observe and describe the basic use of green road users,and to provide the basis for the establishment of the post evaluation system.Then the literature analysis method and the analytic hierarchy process are used to analyze the selected literature samples,and the index set of the evaluation system is preliminarily constructed.By analyzing the data of 266 questionnaires,the comprehensive rating of each greenway was obtained by analytic hierarchy process,fuzzy comprehensive evaluation and SPSS19.0 software,and the degree of satisfaction and difference were analyzed.The third part corresponds to the fifth chapter,that is,the study of optimization and upgrading strategy.By reviewing the research results and collecting data,this paper analyzes the main factors that affect the comprehensive environmental assessment of Beijing central city,and puts forward the existing problems in the connectivity,function and service facilities of the greenway,and aims at the problems,from the design and management of the two aspects of the optimization strategy.The final purpose of the evaluation study of the green road is to provide a healthy,comfortable and ecological landscape for people,so that people can get a sense of happiness and belonging from the natural landscape.This paper is the first time to evaluate the green road built in the central city of Beijing.It provides a reference for improving and improving the construction of the greenway.It has the novelty and innovation.The research has practical guiding significance and broad application prospects for further improving and improving the construction level of Beijing Green Road and giving full play to the ecological function and leisure function of the greenway. |
