Study On Landscape Elements And Continuity Of Living Street In Shenyang Central Urban Area Based On Street View Image

After nearly 50 years of rapid development,China’s urban construction has gradually returned from speed-based to high-quality development,and gradually returned to the original intention of "people-oriented",especially affected by the new crown epidemic,the healthy development of urban space for urban residents has aroused the thinking of scholars from all walks of life.Living streets are the most close to people’s lives of important urban space,but also to meet people’s needs for a better life environment,how to create a beautiful living public space,need to be in-depth research and analysis.This study based on the data of Baidu street view images,in Shenyang city center 11 life street as sample,using the image recognition technology to the streets in the sky,architecture,greening,pavement,motor vehicles and non-motor vehicles each landscape elements such as investigation,sexual life in Shenyang downtown streets landscape elements and its continuity analysis,Urban residents’ visual perception evaluation of street view images was obtained through network questionnaire,and the correlation analysis was conducted by combining the objective material elements and subjective visual satisfaction evaluation results of street view to obtain the impact of landscape elements and element continuity on the visual perception of street view,and the reasonable proportion of landscape elements was discussed.Finally,the elements of sexual life in the streets,on the basis of evaluation and research,the street landscape design of high quality life in-depth thinking,from the aspects of sexual life in Shenyang street each landscape elements of further optimization measures are put forward,to enhance the streets landscape of the whole quality,and construct the evaluation index of the landscape elements to do the further discussion.The research conclusions are as follows:(1)The proportion of living street landscape elements in the downtown area of Shenyang is consistent,with plants,buildings and sky accounting for the largest proportion,with a total of more than 80%,and other pavement and auxiliary elements images accounting for a relatively small proportion.Among the landscape components,the greening level of Shenyang’s living streets is uneven,and the proportion of plant elements in different seasons is relatively large,while in the 11 living street samples selected in the same period,only three streets have a green visual rate of 25%.(2)The average proportion of 11 living street landscape elements is 38%,24%,23%,4%,5%,2%,1%(building,sky,plants,ground,motor vehicles,non-motorized vehicles,facilities),which represents the average proportion of living street landscape elements in the downtown area of Shenyang;the top four streets with landscape visual perception scores are combined and counted,and the proportion of landscape elements is 26%,24%,34%,4%,6%,2%,1%(architecture,sky,plants,Ground,motor vehicles,non-motorized vehicles,facilities),this ratio represents the more reasonable proportion of living street landscape elements in the downtown area of Shenyang.(3)Among the elements of the living street landscape,the three elements of architecture,plants and facilities are significantly related to the subjective evaluation,and the elements such as sky,road surface and motor vehicles are not significantly related to the visual evaluation of the landscape.In the same size of living street space,the openness in the landscape evaluation standard is mainly affected by the building enclosure and building continuity,the higher the proportion of buildings,the greater the continuity,and the worse the openness of the visual experience.The street trees on both sides,as well as the sky,have less impact on street openness.(4)The continuity of buildings in the elements of living street landscape is significantly negatively correlated with the visual perception of streetscape,indicating that the dense buildings in the street will greatly reduce the satisfaction of residents with the landscape;the continuity of greening is positively correlated with the visual perception of streetscape to a certain extent;the proportion of street facilities in the streetscape image and its continuity also have an impact on the visual perception of the landscape;and there is also a significant correlation between the shade of the sky and the visual perception of the landscape in the streetscape image.
