Research On Fragmentation Degree Of Urban Scenery Based On Landscape Vision

In the context of the cultural shock caused by globalization and the acceleration of China’s urban modernization process,the development and protection of Chinese urban landscape is facing unprecedented challenges,and it is facing a crisis of lack of characteristics and cultural rupture.The acceleration of urban construction has plunged the urban landscape into a dilemma of gradual convergence.Some cities "demolition and build" during the renewal process have left permanent trauma to the urban landscape,while the newly shaped urban landscape is the same.In response to this kind of problem,this article attempts to explore and study the shaping and stitching of urban styles with the new concept of "fragmentation of styles" as the starting point.First of all,this article elaborates on the background of the issue of urban style,explores the element indicators that affect style through literature review,studies the definition of urban style,similar concepts of urban style,and urban style components,and analyzes quantifiable elements combined with visual calculations..At the same time,on the basis of the study of urban style and features,the concept of "fragmentation of landscape" is proposed based on the "fragmentation of landscape" in landscape ecology,so as to carry out new researches on the issues of style and appearance in urban construction.Secondly,combined with the landscape vision research,the psychophysical quantitative comprehensive calculation of the evaluation index of the landscape fragmentation is carried out,and the objective calculation result is obtained;the subjective evaluation data is obtained through the public evaluation of a small sample of street view photos.Perform correlation analysis and significance test on subjective and objective data,and establish a calculation model.Use a large sample of public evaluations to test and interpret the model.Finally,based on the evaluation of the fragmentation of the landscape,the current situation of the North City of Hefei City is stitched and planned and the landscape quality is improved.Try to use the concept of "fragmentation of style" to provide new ideas for urban style-related research,hoping to find another way to solve the problem of urban style from a multi-dimensional perspective.
