Research On The Landscape Assessment System Of Urban Roads

Urban road is the frame of a city. It not only reflects the statue of politic, economic and culture of a city, but also is the core of a city's image and landscape. As the economic development and the change of people's lifestyles and concepts, urban road, besides the functions of various transports, also assumes great responsibility of succeeding traditional culture, contents people's aesthetic demands. But now, urban road in China is still far from being able to meet these requirements of these functions. Therefore, the designs and evaluations of the road landscape have already become a new question, it has significant theoretic and practical valve to research on the landscape assessment system of urban roads.This paper elaborates firstly the concept and characteristics of the road landscape, for example, landscape,city,urban road,urban road landscape,the classification and functions of urban roads and so on. Then, the paper carries out a detailed analysis of exposition of the composition element of urban roads landscape, for the dynamic and static elements. Immediately, after the carefully-depth analysis and summary on the each main constituting factor, clearing and defining the object of the evaluation of the road landscape, I discussed the theories of three aspects of landscape, i.e. environmental, function, esthetics and cultural characteristic. Through this project research, we built urban roads landscape assessment system, including 3 levels of targets and 22 factors. Although has some insufficiencies in this evaluation criteria formulation, my study provides some significant the reference to evaluation criteria. This paper recommends several current evaluation methods, for example road landscape comprehensive evaluation method, fuzzy synthetically evaluation, analytic hierarchy process, public-opinion poll and survey analysis, and describes the evaluation steps in detail.At last, taking into account the landscape's objectivity and subjectivity, the characteristics of multiple targets and multiple attribute, I selected two methods, for analytic hierarchy process, public-opinion poll. The landscape evaluation of Ganjiang road is regarded as an example to realize the combine of theory and practice, will provide one kind of reference for the next appraisal work.
